BEST HEADACHE AND MIGRAINE PREVENTION MEDICATIONS AND TREATMENTS, WHEN YOU SHOULD START ONE, AND WHEN YOU SHOULD STOP IT.

@Neuralgroover

BACKGROUND

Migraine is a very disruptive disorder to have to deal with. It interferes with patients’ family, work, and social lives. When the burden of migraine becomes excessive on one or more of these life aspects, preventive migraine therapy should be used. In general, if someone is averaging more than 4 migraines per month, preventive treatment should be offered and discussed, although this number is not an absolute. For example, if someone has 1 migraine per month, but it wipes them out for 1 week and they are missing work, there are certainly variations on when preventive medications should be considered, such as this scenario. If the decision to use a preventive migraine medication has been made, there are several important factors to keep in mind in order to optimize treatment success, as discussed below.

So this blog will focus on migraine preventive meds and treatments, which are a continuous treatment such as a daily pill or a monthly/quarterly treatment such as CGRP mAbs, all of which are detailed below. The goal of migraine preventive treatment is to lessen the frequency and/or severity of migraine attacks. This is in contrast to migraine abortive/acute (as needed) options such as triptans, gepants and ditans. The goal of migraine abortive treatments is to stop individual migraine attacks at onset so the migraine does not reach full severity, ends quickly, and your function is restored and maintained rather than having to go lay down and miss the whole day in bed.  If you have migraine, you want to have both a good abortive and preventive treatment plan to lessen migraine’s nasty habit of interfering and disrupting life and function.

 

TIME

Any preventive medication needs an adequate “therapeutic trial”. In short, you need to be patient and give it enough time to work, as well as get to the correct dose. I see patients all the time that tell me their doctor put them on a medication (usually at too low of a dose), and they stopped it after 3 weeks because it “wasn’t doing anything”. Well, it’s not going to do anything that soon, and that is too early to expect any significant improvement. In general, any preventive medication needs 4-6 weeks to begin working, and 2-3 months until full effect is seen (assuming a good dose has been reached). A good rule of thumb is evaluation of response a minimum of 8 weeks after reaching a target therapeutic dose. If there is a partial response at that time, it’s possible that cumulative benefit can continue to occur over 6-12 months. So the decision on whether to continue really depends on how much benefit has been received, and how well the the patient is tolerating the medication. Unfortunately, there is no way to expedite this process. That doesn’t mean the treatment can’t work sooner. However, that is the standard duration of treatment for a medication to have had a fair trial. Finding a migraine preventive is often a trial and error process. If a treatment is not starting to help by at least 8 weeks at a good dose, changing to a different therapy is suggested. However, once an effective treatment is found, the wait is well worth the decline of migraine frequency and severity!

 

DOSE

In addition to an adequate trial duration, an adequate trial dose is also necessary. For example, a common first line medication used for migraine prevention is Topiramate (which is also FDA approved for migraine prevention). I often see patients who come in on 25 mg or 50 mg and have been on that dose for a year or more without much benefit. I discuss with them that the goal dose is at least 100 mg total daily dose, so the dose is too low. For example, in the migraine preventive trials, once patients reached 100 mg and had been at that dose specifically for at least 4 weeks, that is when improvement of statistical significance began. So, I typically start 25 mg at bedtime for 1 week. Then each week increase by 25 mg at bedtime until 100 mg is reached, and then I give a 100 mg pill to begin. I tell them if there is no improvement starting after at least 4 weeks from reaching the 100 mg dose specifically, let me know. I usually dose it all at bedtime which can help limit side effect potential (since you’ll be sleeping). However, it is generally meant to be taken as a twice daily medicine (such as 50 mg twice daily), and most patients tolerate that fine too.

 

With that said, patients can certainly respond to low doses of medications. However, if improvement has been minimal after a month of a lower dose, it is always a good idea to begin titration up to a better dose. The American Headache Society and American Academy of Neurology published guidelines of migraine preventive medications which includes common goal dose targets for some of these preventive medications here.

 

TREATMENT SELECTION

There are many preventive treatments used, although most of them are considered “off-label” for migraine prevention. This means they are not actually FDA approved for migraine prevention, but there is enough evidence based on research trials or clinical experience to warrant them as a valid option to try. As far as true FDA approved oral (pills by mouth) preventive medications, there are 4 available that have this distinction; Topiramate, Divalproex, Propranolol, and Timolol. There are also a number of natural migraine treatments with supplements which have evidence for migraine prevention, and those are detailed and discussed here.

 

So, let’s discuss migraine prevention medicine.  The categories of oral preventive migraine medications all sound bizarre. They consist of anti-seizure (anti-convulsant), anti-depressant/anti-anxiety, and anti-hypertension (blood pressure) medications. It is important for patients to know that the medicine is being used specifically for migraine. I often see patients who say they didn’t start the medicine their doctor prescribed because they got home, Googled it, and they tell me, “I’m not depressed”. I explain the reasoning for the medication and that it is not for depression, but for migraine prevention since there are overlapping electrical pathways between many of these types of disorders. Furthermore, there are select medications within each of these categories that have evidence from trials and clinical experience for migraine prevention, as listed here and here. For patients that have chronic migraine (15 or more headache days per month with 8 or more days having migrainous features), Botox is another highly effective option to consider.

 

It is also important to know that the medications in each of these medication classes are not a “one size fits all” for every medicine within that category. For example, there is no good evidence for migraine prevention in the SSRI (selective serotonin reuptake inhibitors) anti-depressant/anti-anxiety medication category (Fluoxetine, Sertraline, Escitalopram, Citalopram, etc.). However, there is evidence for benefit in some of the SNRIs (serotonin and norepinephrine reuptake inhibitors) such as Venlafaxine XR, Duloxetine, as well as some of the TCAs (tricyclic antidepressants), primarily Amitriptyline and Nortriptyline. Similarly, there are select medications within the anti-seizure/anti-convulsant category which have the best evidence (Topiramate, Divalproex), as well as the anti-hypertension category (Propranolol, Metoprolol, Atenolol, Nadolol, Verapamil).

 

There are now 4 monoclonal antibody CGRP receptor antagonists which have this FDA approval for migraine prevention also. Three of them are once monthly auto/self-injections (Aimovig, Ajovy, Emgality), and one is a once quarterly (every 3 months) 30 minute IV (intravenous) infusion (Vyepti). In general, these are an option for those with 4 or more migraines per month on average.  The great thing about these treatment options as opposed to standard pill options is that they do not require a gradual dose escalation, they tend to have a much more rapid onset of improvement, and they have very low side effect risk. These medications are all discussed in much greater detail and comparison here.

 

Neuromodulatory devices that are FDA cleared for migraine prevention are also available and include sTMS (SAVI, SpringTMS, sTMS mini),  eTNS (CEFALY), and nVNS (GAMMACORE), all of which are discussed in much greater detail here. There are also nutraceuticals and supplements which have good evidence for migraine prevention. Yoga, relaxation and wellness therapies are also helpful in migraine prevention.

 

An exciting development is that there are 2 migraine preventive medications in the new gepant classification which are currently in clinical trials, and showing good evidence of effectiveness. They are both oral pills and include Atogepant and Rimegepant (currently FDA approved for abortive migraine treatment under the name Nurtec ODT 75 mg). So these will open up another new class of preventive migraine medications engineered purely for migraine treatment! Notably, Biohaven submitted a request to the FDA in October 2020 to approve Rimegepant as a preventive migraine treatment, in addition to its current migraine abortive FDA approved indication. This decision is pending. This move followed clinical trials showing that patients taking 75 mg of Rimegepant every other day experienced a 4.3 day reduction from baseline in monthly migraine days.

 

When choosing a preventive treatment, I like to fine-tune the treatment to “hit as many birds with one stone”. In other words, pick something that will not only help with migraine prevention, but may also help with other medical conditions at the same time. Doing this can allow you to help minimize the number of medications used overall, by using something with benefit for several disorders in addition to the migraine. For example, if someone has depression or anxiety, targeting their migraine preventive medication with an anti-depressant/anti-anxiety category would make sense. If the patient has other chronic musculoskeletal pain issues, fibromyalgia, occipital neuralgia, etc., the SNRIs and the TCAs are good considerations. If the patient has insomnia, Amitriptyline or Nortriptyline are great options. If they have seizures, an anti-seizure medication such as Topiramate or Divalproex would make sense. If they are overweight, Topiramate also causes weight loss. Divalproex is another anti-seizure medicine which is also FDA approved for migraine prevention. However, this should be avoided when possible in young women of child-bearing age given the high risk of congenital birth defects while taking it (and most pregnancies are unplanned).

Here are some treatment considerations to take into account for migraine preventive therapy in addition to the following medical conditions the patient may also have:

-Obese/Overweight: Topiramate (Topamax), Topiramate ER/XR (extended release, Trokendi or Qudexy XR), Zonisamide  (Zonegran): All can cause weight loss, which can be helpful in overweight patients. However, use with caution if patient is extremely thin to limit further weight loss. If they improve with Topamax, but have Topamax side effects (numbness and tingling, word-finding difficulty, speech disturbances, memory and cognitive disturbances, mood changes), changing to Topiramate ER/XR (extended release) or Zonisamide tend to have similar benefit with less side effects. Women who are on oral contraceptive pills are often warned prematurely by their pharmacist that Topiramate will effect their oral contraceptive. This is partly true. Topiramate at a daily dose of 200 mg or less does not interact with oral contraceptives according to this study, but it can at higher doses which could potentially decrease effectiveness. However, the goal dose for effective migraine prevention is typically 100 mg per day, well below that 200 mg dose that could impact effectiveness of the oral contraceptive. I would avoid Amitriptyline, Nortriptyline since there is a risk of weight gain for some.

-Underweight/Excessively thin: Side effects of Nortriptyline and Amitriptyline can occasionally be weight gain (but not necessarily), but this may be beneficial in some patients.

-Depression and/or anxiety: Venlafaxine ER, Duloxetine, Amitriptyline, Nortriptyline, Desvenlafaxine

-Mood disorder such as bipolar or psychosis: Divalproex, Topiramate, Carbamazepine

-Anxiety without depression: Venlafaxine ER, Amitriptyline, Duloxetine, Nortriptyline, Desvenlafaxine, Propranolol

-Insomnia: Amitriptyline, Nortriptyline

-Fatigue/Low energy: Venlafaxine ER, Duloxetine (these can be energizing for many, so are best taken in morning)

-Hypertension: Propranolol, Metoprolol, Nadolol, Atenolol, Lisinopril, Candesartan, Verapamil

-Palpitations: Propranolol, Metoprolol, Nadolol, Atenolol

-Chronic musculoskeletal pains, fibromyalgia, neuropathy/nerve pains: Amitriptyline, Duloxetine, Nortriptyline, Gabapentin

-Pregnancy: This one is tricky since the goal during pregnancy is to minimize the use of as many medications as possible. Mindfulness treatments such as yoga and meditation are always good recommendations. With that said, the first line option we typically begin with is magnesium supplementation of 400-800 mg daily. If a prescription medication is needed, cyproheptadine 4 mg at bedtime has been a long time medicine used in this scenario, and it can be titrated to 4 mg three times daily if needed. The good thing with pregnancy is that migraines improve in about 2/3rd of women (especially 2nd and 3rd trimester), and it is not uncommon to hear that migraines resolved during pregnancy. So many times a preventive treatment may not even be needed. For menstrually related migraine outside of pregnancy, further discussions and treatment considerations can be read here.

-Epilepsy: Topiramate, Topiramate ER/XR (extended release), Divalproex, Carbamazepine, and Zonisamide are the anticonvulsant medications we see most useful for migraine prevention. In fact, Topiramate and Divalproex are also FDA approved for migraine prevention. If patients improve with Topiramate but have side effects, changing to Topiramate ER/XR (extended release) or Zonisamide tend to have similar benefit with less side effects. Women who are on oral contraceptive pills are often warned prematurely by their pharmacist that Topiramate will effect their oral contraceptive. This is partly true. Topiramate at a daily dose of 200 mg or less does not interact with oral contraceptives according to this study, but it can at higher doses which could potentially decrease effectiveness. However, the goal dose for effective migraine prevention is typically 100 mg per day, well below that 200 mg dose that could impact effectiveness of the oral contraceptive.

-Non-oral route needed or preferred: Once monthly self/auto injections of monoclonal antibody CGRP receptor antagonists (Aimovig, Ajovy, Emgality) or once quarterly 30 minute IV infusion (Yvepti), which are all detailed here. Botox is another non-pill option for those averaging 15 or more headache days per month with at least 8 of those days having any migrainous features (throbbing, nausea, sensitivity to light (photophobia) or sound (phonophobia)) for 3 or more consecutive months (chronic migraine). Neuromodulatory devices that are FDA cleared for migraine prevention are also available and include sTMS (SAVI, SpringTMS, sTMS mini),  eTNS (CEFALY), and nVNS (GAMMACORE), all of which are discussed in much greater detail here.

-Averaging 15 or more headache days per month with at least 8 of those days having any migrainous features (throbbing, nausea, sensitivity to light (photophobia) or sound (phonophobia)) for 3 or more consecutive months (chronic migraine): Botox (Onabotulinumtoxin-A) injections every 3 months according to the PREEMPT chronic migraine treatment protocol. This is the only truly FDA approved medication for prevention of chronic migraine as of 2010. Any of the above listed medications are also options to consider, and most insurances will require failure of at least 2 classes of preventative oral medications before Botox is approved anyway, but this varies by insurance.

 

EXPECTATIONS

Expectations in migraine management are important. If your expectation is that your migraines will stop completely when you use preventive medications, you will be sorely disappointed. Of course it can certainly happen, but that is rare and should never be the expectation or goal. The goal of preventive therapy is a decrease in migraine frequency and/or severity of attacks (optimally both) to some extent to make them more tolerable and less intrusive into life. A general goal is 50% improvement in frequency and/or severity. Some patients can get much more than that, while others get much less (which would signal trials of a different medication class). With that said, success with migraine preventive benefit can also be considered in significant decreases is migraine attack duration or severity, reduction in migraine associated disability, improving the patient’s functioning in various areas of life, improvements in quality of life, and improvement in acute treatment responses. In general, studies estimate that about 45% of patients on conventional preventive therapy (such as oral medications) receive 50% reduction in monthly migraine days. Thus, 55% will receive less improvement than this. The CGRP mAbs tend to have a higher rate of improvement then conventional treatments as detailed here.

 

WHEN TO STOP

There is no absolute answer of when to stop preventive therapy. It depends on how well one is doing, how long they have been doing well, and how much they want to get rid of treatments. Some people want off as soon as they can, others prefer to stay on for years since they are doing very well with few migraines, and don’t want to “rock the boat”. In general, the goal is to continue preventive therapy until the patient is doing significantly better for at least 3 months, but preferably closer to 6 months or so. I always make sure to tell patients that preventive medicines or treatments are not necessarily meant to be a life-long commitment. Rather, we use these treatments to “reboot” and “reset” the brain’s electrical system to have less frequent and/or severe migraines, and then try to sneak away off the medications once they are consistently doing better.

NATURAL MIGRAINE TREATMENT FOR PREVENTION WITH VITAMINS AND SUPPLEMENTS. WHICH ARE BEST?

@Neuralgroover

Worldwide, migraine affects more than 10-12% of the population, with approximately 1 billion migraineurs estimated worldwide.1 It is estimated that there are 39 million migraineurs in the US, accounting for 12% of the US population. Migraine affects 18% of women and 6% of men2,3. Nearly 25% of U.S. households include someone with migraine.

 

In 2016, migraine was determined to be the 2nd leading cause of all global disability, and the 2nd leading cause of all neurological disease burden4. Migraine accounts for 50% of all neurologic disability. Furthermore, chronic pain in general is the largest contributor to years lived with disability globally5, and is associated with tremendous negative impacts on social, economic, and personal function.

 

In addition to the attack-related disability, many sufferers live in fear because their migraines disrupt their ability to work, go to school, partake in social activities, or care for their families, and this significantly limits their overall quality of life. More than 90% of migraine sufferers are unable to work or function normally during their attacks. American employers lose more than $20 billion each year as a result of 113 million lost workdays due to migraine.6

 

Migraine treatment is divided into acute (as needed) and preventive (prophylactic) therapy. Most existing preventive therapies are adopted from anti-epileptic, antidepressant, and antihypertensive medications. However, many of these medications are not well tolerated, resulting in poor compliance. Adherence to oral migraine preventative medication is around 26% at 6 months and declines to 17% at one year.7 This is often due to intolerable side effects. Many patients, due to lack of efficacy of preventative treatments, often resort to overuse of acute medications. This results in additional decline in quality of life and economic burden.8 Onabotulinumtoxin-A (Botox) is currently the only FDA-approved treatment available for chronic migraine. However, most patients must fail at least three preventative treatments prior to receiving Onabotulinumtoxin-A. As such, Onabotulinumtoxin-A is typically a fourth line option for the prevention of chronic migraine. In addition, it is not approved for patients who have episodic migraine. There are 4 calcitonin gene related peptide (CGRP) monoclonal antibody antagonists that have been approved for the prevention of migraine.  There also exists a limited number of neuromodulatory devices. Lack of insurance coverage of these devices precludes their routine use in clinical practice.  This confers a large unmet need for additional preventive migraine treatments and additional therapeutic targets.

 

Migraine prevention is a key aspect to maintaining a good quality of life.  Abnormal neuronal membrane ion channels, low ionized magnesium levels, increased excitatory glutamatergic activity, and mitochondrial dysfunction with abnormal energy metabolism are associated with migraine. The goal of nutraceuticals is to target these factors in order to improve energy metabolism and reduce neuronal hyperexcitability in the brain. Patients often seek natural migraine treatment with complementary and alternative medicine (CAM) after finding standard prescription treatments intolerable due to side effects, or just ineffective. Many patients feel that “natural” substances are less toxic than prescription medications. Thus, the nutraceutical and herbal supplement industry is a multibillion-dollar industry. CAMs include, but are not limited to, nutraceuticals (vitamins and supplements such as magnesium, coenzyme Q10 (CoQ10), vitamin B2 (riboflavin), alpha lipoic acid, vitamin D, 5-HTP, fish oil, melatonin), and herbal preparations (butterbur, feverfew, ginger, and cannabidiol). Other natural treatments such as yoga and meditation for migraine treatment can also be very helpful.

 

The use of CAMs has been significantly rising in the US and Europe9–12, and is becoming more evident especially in patients with migraine and other headache disorders. In a recent questionnaire-based survey in Germany and Austria, 81.7% of patients seen in tertiary outpatient headache clinics reported use of CAM13.  There are a multitude of different migraine related supplements on the market with variable combinations or sold separately as the individual components. Below, we discuss the most commonly used and studied supplements for migraine prevention.

 

VITAMINS and SUPPLEMENTS FOR MIGRAINE PREVENTION:

  1. Magnesium

Magnesium has a Level B (2nd highest) evidence recommendation for migraine prevention by the American Academy of Neurology and American Headache Society.14 It is also rated highly and recommended by the Canadian Headache Society.15 This is a higher evidence recommendation than many of the prescription medications we use for migraine prevention. More than 325 enzymes are magnesium dependent, many of which are brain enzymes. Magnesium is involved in all reactions that involve the formation and utilization of adenosine-5′-triphosphate (ATP) in energy metabolism16–19. Proper magnesium levels are known to help normalize blood pressure, have anticoagulant, anti-platelet aggregating effects, regulate cell proliferation, protein synthesis, cellular energy and cell membrane stability, as well as blood sugar levels19–21. Studies have shown low levels of brain magnesium22,23 may be a contributor to migraine pathophysiology. Magnesium influences multiple steps in the current understanding of migraine pathophysiology including cortical spreading depression, serotonin receptor activity, neurotransmitter release, interference with inflammatory mediators, nitric oxide production, platelet aggregation, vascular tone, NMDA receptor interaction, CGRP release, production and release of substance P which activates pain fibers24–31. Magnesium is a mineral that functions as a coenzyme for various neurologic functions and other physiologic mechanisms.    According to two double-blind studies, high-dose oral magnesium supplementation appears to be effective in migraine prophylaxis. Trials have shown that magnesium supplementation is very effective in migraine treatment, with migraine attack reductions of up to 42%.32–37 Other studies have also shown benefit in migraine prevention when combined with coenzyme Q10 and feverfew as well.38 Magnesium (250 mg twice a day or 500 mg at bed) has a relaxant effect on smooth muscles such as blood vessels. We often give intravenous magnesium to patients who come into the emergency department for migraine because it helps to break the migraine. Three trials found 40-90% average headache reduction when used as a preventative. Magnesium also demonstrated the benefit in menstrually related migraine. Magnesium is part of the messenger system in the serotonin cascade and it is a good muscle relaxant. Some forms can be useful for constipation which can be a side effect of other medications used to treat migraine. Good sources include nuts, whole grains, and tomatoes.

 

There are different forms of magnesium, and we’ll discuss the most common types. Magnesium types can be tailored to patient characteristics as follows.39 Magnesium glycinate is a good choice for those with a sensitive stomach who have gastrointestinal side effects such as diarrhea with other forms of magnesium. It is anecdotally also helpful with anxiety and sleep. Magnesium threonate also has low risk of gastrointestinal side effects and anecdotally helpful with cognitive function and brain fog symptoms. Magnesium malate has low gastrointestinal side effects and is reportedly more energizing and anecdotally often helpful in fibromyalgia and chronic fatigue syndrome. Magnesium citrate is one of the most studied, popular, and well-absorbed forms of magnesium. It can also be mixed easily with liquids if you can’t take pills. However, it comes with a higher risk of diarrhea and gastrointestinal side effects, although this could be helpful for those with constipation. Magnesium oxide is also well studied, cheap, and often used for heartburn and indigestion. However, it is not well absorbed and can have some laxative side effects as well, so can also be helpful for constipation.

 

Dosing should generally be somewhere between 400-800 mg daily. It should preferably contain 24 mmol (600 mg) of elemental magnesium daily as magnesium citrate​ based on trials that showed benefit with this specific one more than others, and this is the recommendation of the Canadian Headache Society.15 If this type is not tolerated, other forms of magnesium as discussed above are certainly acceptable.

 

  1. Vitamin D3 (Cholecalciferol)

Vitamin D deficiency is a worldwide problem. Vitamin D is not actually a vitamin, but a hormone that the body makes from a type of cholesterol in the skin when it is exposed to UVB radiation from the sun. Small amounts also come from diet. It has anti-inflammatory activities, analgesic effects, may reduce nitric oxide and assists in magnesium and calcium absorption. Deficiency is suspected to play a role in mechanisms responsible for migraine and other pain syndromes, and vitamin D levels have been shown to be low in chronic migraineurs40. The best form is vitamin D3 (cholecalciferol) anywhere from 1,000 to 4,000 IU daily.

 

  1. 5-HTP (5-Hydroxytryptophan)

This is an amino acid that is made by the body from tryptophan (amino acid you get from your diet), and is involved in mood, sleep, and pain regulation. 5-HTP is typically produced from the seeds of the Griffonia simplicifolia plant. 5-HTP is converted into serotonin (5-hydroxytryptamine), an important brain neurotransmitter involved in migraine pathways and other neurologic pathways. 5-HTP is also converted into melatonin which aids in sleep, as well as dopamine, another important neurotransmitter. The effects of 5-HTP are felt to be similar to the antidepressants that are thought to increase the amount of serotonin available to the brain, and thus a mood enhancing chemical. Some studies have suggested that 5-HTP was as effective as some prescription migraine medications such as propranolol and methysergide (75% improvement in methysergide vs. 71% improvement in 5-HTP) in reducing the frequency and severity of migraines41–45. Side effects can include nausea, diarrhea, and stomach pain, and it should be used cautiously with medications which increase serotonin levels (such as most antidepressants) due to potential risk of serotonin syndrome. Typical doses are around 100–200 mg, 2–3 times per day with meals.

 

  1. Fish oil (Eicosapentaenoic acid (EPA) + Docosahexaenoic acid (DHA))

Fish oils are found in the tissues of fish. They contain a certain type of fat called omega-3. Potential mechanisms for anti-inflammatory effects of fish oil include inhibition of inflammatory mediators (eicosanoids and cytokines), and synthesis of lipid suppressors of inflammation (resolvins)46. Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) give rise to these resolvins which are anti-inflammatory and inflammation resolving47. These compounds may relieve joint pain and stiffness in a similar way as non-steroidal anti-inflammatory drugs (NSAIDs)46,48. One study reported dramatic decreases in headache frequency (15 per month down to 2 per month) and decreases in headache severity (reduction from 5 to 3 on a 7-point scale)49. Fish oils have also been studied and found to be useful in other inflammatory conditions such as rheumatoid arthritis46,48,50–53. Large trials have showed a significant beneficial effect on pain, morning stiffness, number of painful and/or tender joints and NSAID consumption50. Recommended dosing consists of 30% EPA and DHA with a ratio of EPA to DHA of 1.5. Research suggests the minimum dose needed to reduce the joint inflammation associated with arthritis is 2.7 grams of omega-3 (EPA + DHA) daily, which could also be divided such as 900 mg EPA and 450 mg DHA twice daily.

 

  1. Melatonin:

Increasing evidence shows correlation between melatonin secretion and headache conditions. Melatonin supplementation has shown decreased headache intensity and duration. It is widely used as a sleep aid. Sleep is nature’s way of dealing with migraine. A dose of 3 mg is recommended to start for headaches including cluster headache. Higher doses up to 15 mg has been reviewed for use in cluster headache and have been used, if not making too groggy in the morning. The rationale behind using melatonin for cluster is that many theories regarding the cause of cluster headache center around the disruption of the normal circadian rhythm in the brain. This helps restore the normal circadian rhythm. It should be taken at least 2 hours before bedtime.

 

MITOCHONDRIAL SUPPLEMENTS FOR MIGRAINE PREVENTION:

Mitochondria are the powerhouses within all cells of the body. These crucial metabolic organelles use oxygen to produce ATP, which is the primary energy source for the cell, and thus, for your body. Mitochondrial dysfunction leads to impaired oxygen metabolism and is suspected to play a role in migraine pathophysiology. Some migraineurs have been shown to have reduced mitochondrial activity which may lead to altered neuronal processing, and therefore a lower threshold for migraine attacks54–58. Riboflavin (vitamin B2), CoQ10 (ubiquinone; CoQ10), and alpha lipoic acid (thioctic acid) all play key roles in mitochondrial activity, and therefore have been implicated in migraine treatment by optimizing mitochondrial functioning.

 

  1. Riboflavin (Vitamin B2)

Riboflavin assists nerve cells in the production of ATP, a principal energy storing molecule. Riboflavin is an essential precursor to coenzymes involved in electron transport in oxidation reduction reactions within the Krebs cycle. This metabolic cycle is critical in production of ATP and generation of energy in the mitochondria, oxidative metabolism, maintaining membrane stability, and for all energy-related cellular functions59,60. It is necessary for many chemical reactions in the body. Brain riboflavin metabolism is suspected to affect migraine pathophysiology via several mechanisms, providing migraine preventive benefit.36,37

 

Riboflavin has a Level B (2nd highest) evidence recommendation for migraine prevention by the American Academy of Neurology and American Headache Society.14 This is a higher evidence recommendation than many of the prescription medications we use for migraine prevention. The Canadian Headache Society Guidelines strongly recommend B2 for migraine prevention as well.15 There have been at least 3 clinical trials of riboflavin using 400 mg per day all of which suggested that migraine frequency can be decreased. All 3 trials showed significant improvement in over half of migraine sufferers. Trials of riboflavin have suggested significant improvements in migraine by up to 59%61. Riboflavin (Vitamin B2): 200 mg twice a day (or 400 mg daily). The supplement is found in bread, cereal, milk, meat, and poultry. Most Americans get more riboflavin than the recommended daily allowance, however riboflavin deficiency is not necessary for the supplements to help prevent headache. One side effect to be aware of is that it can turn your urine bright neon yellow, although this is not harmful. Recommended dosing is 200 mg twice daily (or 400 mg once daily).

 

  1. Coenzyme Q10 (Ubiquinone; Ubiquinol; CoQ10)

CoQ10 is present in every membrane of all cells in the body62. Similar to riboflavin, CoQ10 plays a crucial role in electron transport and energy metabolism given its heavy involvement in mitochondrial function. CoQ10 is incorporated into the mitochondria, where it facilitates the transformation of fats and sugars into energy, thus it is often marketed to be an “energy enhancer”. Studies have shown that a nutritional supplement of CoQ10 can reduce the frequency of migraine attacks by improving the energy production of cells as with riboflavin. It also functions as an antioxidant by protecting against toxic oxidative reactions in the body, and CoQ10 tissue levels are known to decrease with age19,63. In one study, CoQ10 was found to be low in about 1/3rd of patients studied, and when replaced, headache frequency improved64. Migraine frequency was shown to improve significantly in more than 61% of patients in one study65, and 50% of patients in another study,66 supporting use for migraine prevention.36 Other studies have also shown benefit in migraine prevention when combined with magnesium and feverfew as well.38 The Canadian Headache Society guidelines strongly recommend use of CoQ10.15 Suggested dosing is around 150 mg-200 mg twice a day.

 

  1. Alpha Lipoic Acid (Thioctic Acid)

Alpha lipoic acid enhances the metabolism of oxygen and energy production by mitochondria67, and has shown reduction of migraine frequency68 when studied. Doses are typically around 300 mg twice daily.

 

HERBAL SUPPLEMENTS FOR MIGRAINE PREVENTION:

  1. Feverfew (Tanacetum parthenium)

Feverfew is a common garden herb native to Europe and popular in Great Britain as a treatment for disorders typically controlled by aspirin. The mechanism of action is unknown but is believed to be related to a chemical called parthenolide which helps the body use serotonin more effectively. Serotonin helps prevent migraine and assists with resolution when it occurs. Parthenolide also inhibits the release of histamine which is linked to pain and inflammation. Consistency of active ingredients in different products can be a problem. Some formulations don’t have the active ingredient (parthenolide) that prevents migraine. A parthenolide content of 0.2% is generally recommended.

 

Feverfew has a Level B (2nd highest) evidence recommendation for migraine prevention by the American Academy of Neurology and American Headache Society.14 This is a higher evidence recommendation than many of the prescription medications we use for migraine prevention. The anti-migraine action36–38,69–75 of Feverfew is felt to be related to the parthenolides within the leaves. Studies have shown that the parthenolides provide anti-inflammatory and analgesic effects through several mechanisms involved in the migraine process that normally lead to pain. These include inhibition of phospholipase A, prostaglandin biosynthesis and platelet aggregation, and actions on serotonin including release of serotonin from platelets and white blood cells, as well as interaction at various serotonin receptor subtypes19,76–89. Study results have been variable based on wide variations in the strength of the parthenolides and differences in the stability of feverfew preparations used. However, a new, more stable feverfew extract (MIG-99) was created and showed a significant improvement in patients with high-frequency migraine90,91. The recommended dosing is generally around 50 mg twice daily (standardized to a high parthenolide content of 0.7% and stability measures of parthenolide), or, preferably MIG-99 6.25 mg three times daily if it can be found.

 

  1. Butterbur Extract (Petasites hybridus)

Butterbur is an extract derived from the petisides hybridus root, which has been used for medicinal purposes since ancient times. Butterbur is a well-researched and proven herbal supplements for migraine prevention36,69,70,92. For many years, it was the only supplement with a Level A (highest) evidence recommendation for migraine prevention by the American Academy of Neurology and American Headache Society,14 with a higher evidence recommendation than many of the prescription medications we use for migraine prevention. However, this recommendation was withdrawn a few years ago given a small handful of cases of liver failure reported in Germany. Although it is classified as an herbal supplement in the US, it is a licensed pharmaceutical medicine in Germany (Petadolex). Its two active compounds, petasin and isopetasin, help reduce cerebral blood vessel spasm and stop the inflammatory cascade which occurs in migraine93–95. Butterbur is thought to act through anti-inflammatory inhibition of leukotriene biosynthesis for its analgesic effects but also has calcium channel regulatory properties, both of which play a role in migraine19.

 

Studies have also shown anti-inflammatory effects mediated through inhibiting the additional inflammatory enzymes cyclooxygenase and prostaglandin production96. Notably, this is also what gives aspirin its anti-inflammatory effect. Trials have shown very positive results with significant decreases in migraine frequency of up to 58-77%, with 91% reporting overall improvement97–100. Side effects can include burping/belching. Raw butterbur root contains toxic chemicals that must be filtered out during the manufacturing process. To be sure you are choosing a safe product, look for a formulation that does not contain pyrrolizidine alkaloids since these are toxic to the liver. Recommended dosing is typically around 75 mg twice daily (free of Pyrrolizidine Alkaloids (PAs), standardized to contain a minimum of 7.5 mg of petasin and isopetasin).

 

  1. Ginger (Zingiber Officinale)

Ginger has anti-histamine and anti-inflammatory properties such as blocking pain-producing prostaglandins101,102, and helps with circulation and potentially headache. It is also widely used to treat nausea and vomiting, which accompany migraine103, and this is what it is primarily useful for. Recommended dosing ranges from 100-200 mg three times per day to 150 mg twice daily (standardized to contain 20% of gingerol and shogaol (dosage).

 

  1. CBD (Cannabidiol)

There have been a multitude of studies documenting the analgesic and anti-inflammatory benefits of medicinal cannabis (marijuana) across many chronic pain syndromes104–106, and it has been a historical treatment for headache and migraine for centuries.105–109 A detailed overview of medical cannabis for the treatment of migraine and chronic pain is discussed here. The vast majority of supporting evidence of cannabis and cannabinoids involves various chronic pain syndromes. These benefits are hypothesized to extend to headache disorders such as migraine given overlapping neurobiological pathways of pain. Some data suggests that cannabinoids appear to work uniquely within the inherent anatomical pathways of migraine (including serotonergic triptan pathways) and pain.104,105,107–139 Unfortunately, the majority of data supporting the use of cannabis and cannabinoids in migraine and headache disorders is based on case series, case reports, surveys and anecdotal evidence.105,107,145–154,108,155–161,134,135,140–144 There has been one retrospective study of cannabis use in the treatment of migraine which reported strong statistically significant findings of benefit.162 There have been only two limited prospective trials of cannabinoids containing a control group in headache disorders. One reported significant benefit in chronic daily headache associated with medication overuse headache,163 and the other reported significant benefit in both the acute and preventive treatment of chronic migraine.164

 

Given the growing evidence of cannabis and cannabinoids in the treatment of chronic pain and other medical conditions, in February 2019 The World Health Organization (WHO) recommended that cannabis be rescheduled and removed from the most restrictive scheduling category. In January 2017, the National Academies of Sciences, Engineering, and Medicine concluded that the use of cannabis for the treatment of pain is supported by well-controlled clinical trials and that there is substantial evidence that cannabis is an effective treatment for chronic pain in adults.165 In 2014, the Canadian Pain Society revised their consensus statement to recommend cannabinoids as a third-level therapy for chronic neuropathic pain based on the abundance of supporting evidence and a NNT (number needed to treat) estimated at approximately 3.166

 

Delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the two predominant cannabinoids found in cannabis and are discussed in more detail here. CBD is several hundred more times anti-inflammatory than aspirin.104 There have been scientific, animal models, and limited human clinical trials documenting its anti-inflammatory and analgesic properties.167–176 In contrast to THC, CBD is non-intoxicating (no “high”).167 In November 2017, The World Health Organization (WHO) concluded that CBD exhibits no evidence for abuse or dependence potential, and that there is no evidence of public health related concerns associated with its use.177 In January 2018, the World Anti-Doping Agency (WADA) removed CBD from their prohibited list, no longer banning use by athletes.178

 

In December 2018, the Agriculture Improvement Act (Farm Bill) was signed into law in the United States. This legalized the agricultural growth and use of hemp (cannabis strains containing 0.3% THC or less) and hemp derivatives such as CBD, as well as removed hemp and its extracts (including CBD) from the Controlled Substances Act, making it no longer an illegal substance under federal law.

 

Thus, the use of CBD products has been exploding and is a new industry projected to exponentially increase into a multi-billion dollar industry179,180. Many patients are using these products for a variety of reasons181,182, most commonly in pain, including migraine prevention, given their easy access and availability. However, there are no studies evaluating CBD alone in treatment of migraine or any other headache disorders, so this is purely anecdotal. CBD products can readily be purchased online from a multitude of companies, in local health food and drug stores, and common retail pharmacies.183 CBD and suggested dosing (which are not currently clearly known) are discussed in much greater detail here. Medical marijuana (cannabis) for the treatment of migraine is also discussed in much greater

CBD (CANNABIDIOL) FOR MIGRAINE, HEADACHE, AND PAIN. EVERYTHING YOU NEED TO KNOW.

@Neuralgroover

BACKGROUND

CBD (cannabidiol) for migraine, headache, pain, chronic pain, arthritis, and other medical conditions are topics that patients are increasingly asking about. Why? CBD is everywhere! You can buy it at the local grocery store, supplement store, gas station, video rental store, and almost anywhere else nowadays. There are hundreds of brands. Is it right for you? Will it work? How do you take it? How do you know which products are of good quality and are safe? Are there downsides? Are there side effects? Will you test positive on a drug screen? These are a few of the many questions you likely have. Our patients ask about CBD use all the time in regard to migraine and pain. So, I decided to write this blog to provide an overview and answer these burning questions you may have!

 

There have been a multitude of studies documenting the analgesic and anti-inflammatory benefits of medicinal cannabis across many chronic pain syndromes1–4, and it has been a historical treatment for headache and migraine for centuries.2,3,5–7 An extensive discussion of medicinal cannabis, or medicinal marijuana, for chronic pain, headache, and migraine can be read here. The vast majority of supporting evidence of cannabis and cannabinoids involves various chronic pain syndromes. These benefits are hypothesized to extend to headache disorders such as migraine given overlapping neurobiological pathways of pain. Some data suggests that cannabinoids appear to work uniquely within the inherent anatomical pathways of migraine (including serotonergic triptan pathways) and pain.1,2,5–37 Unfortunately, the majority of data supporting the use of cannabis and cannabinoids in migraine and headache disorders is based on case series, case reports, surveys and anecdotal evidence.5,6,32,33,38–57 There has been one retrospective study of cannabis use in the treatment of migraine which reported strong statistically significant findings of benefit.58 There have been only two limited prospective trials of cannabinoids containing a control group in headache disorders. One reported significant benefit in chronic daily headache associated with medication overuse headache,59 and the other reported significant benefit in both the acute and preventive treatment of chronic migraine.60

 

The endocannabinoid system is a normal and important biological system within everyone. It plays a role in many regulatory physiological processes across all organ systems, and is widely distributed throughout the central nervous system (brain and spinal cord) and peripheral nervous system (nerves outside of the spinal canal). Notably, it plays a strong role in pain pathways. This system works by the interaction of our own natural endocannabinoids turning on or turning off various endocannabinoid receptors throughout our body.

 

Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are the two predominant cannabinoids found in cannabis (marijuana). Cannabinoids are unique to the cannabis plant, and can be thought of as the “plant equivalents” of our own endocannabinoids. So, they interact with the same endocannabinoid receptors in our body as our own endocannabinoids do. Given the growing evidence of cannabis and cannabinoids in the treatment of chronic pain and other medical conditions, in February 2019 The World Health Organization (WHO) recommended that cannabis be rescheduled and removed from the most restrictive scheduling category. In January 2017, the National Academies of Sciences, Engineering, and Medicine concluded that the use of cannabis for the treatment of pain is supported by well-controlled clinical trials and that there is substantial evidence that cannabis is an effective treatment for chronic pain in adults. In 2014, the Canadian Pain Society revised their consensus statement to recommend cannabinoids as a third-level therapy for chronic neuropathic pain based on the abundance of supporting evidence and a NNT (number needed to treat) estimated at approximately 3 (the number of patients needed to treat for 1 of them to receive benefit). So naturally, there has been a quickly growing public interest in these potential therapies for a variety of reasons, especially in pain disorders.

 

THC causes the psychoactive qualities (“high”) of cannabis. THC has been shown to be 20 times more anti-inflammatory than aspirin and 2 times as anti-inflammatory as hydrocortisone. It is also a potent anti-emetic (anti-nausea), which is why there are two FDA-approved synthetic THC medications for chemotherapy related nausea and vomiting (Dronabinol, Nabilone). The existing literature and research on the treatment of pain have primarily studied cannabis itself with its variable and often undefined combinations of THC, CBD, other cannabinoids, terpenes, and other constituents. The medicinal benefits of cannabis are suspected to be from the “entourage effects” from synergistic action (working together) between various cannabinoids such as THC and CBD, and terpenes.1,61

 

In contrast to THC, CBD is non-intoxicating (no “high”). CBD has been shown to be several hundred more times anti-inflammatory than aspirin. Greater than 65 molecular receptor targets and greater than 80 mechanisms of action have been identified. There have been scientific, animal models, and very limited human clinical trials documenting its anti-inflammatory and analgesic (pain-relieving) properties. However, there are no high-quality research studies to date evaluating isolated pure CBD in any pain, migraine, or other headache disorders. So, it is unclear how much benefit CBD in isolation provides outside of the presumed entourage effects that it contributes to.

 

In November 2017, The World Health Organization (WHO) concluded that CBD exhibits no evidence for abuse or dependence potential, and that there is no evidence of public health related problems associated with its use. In January 2018, the World Anti-Doping Agency (WADA) removed CBD from their prohibited list, no longer banning use by athletes. In December 2018, the Agriculture Improvement Act (Farm Bill) was signed into law. This legalized the agricultural growth and use of hemp (cannabis strains containing 0.3% THC or less) and hemp derivatives such as CBD. The Farm Bill also removed hemp from the Controlled Substances Act, making it no longer an illegal substance under federal law. To review, up until the Farm Bill was passed, any form of cannabis or cannabis derivatives (including CBD) have been federally illegal since the Controlled Substance Act of 1970, which is when cannabis was changed to a Schedule 1 drug of which it has remained since. Therefore, it is important to remember that cannabis chemovars (strains) and CBD oils with greater than 0.3% THC are still considered marijuana, and thus are illegal federally, require a medical marijuana card for use, and are illegal to cross state lines with. In May 2019, TSA began to allow travel with CBD products containing 0.3% or less of THC.

 

Thus, the use of CBD products has been exponentially increasing for a wide variety of uses, including pain and headache, and anecdotal benefits are commonly reported. Although the various CBD companies provide guidance on dosing, there are no standardized dosing guidelines on optimal dosing, and strengths and frequencies used are widely variable. Some cannabinoid experts feel that most over the counter bought CBD products have too low of milligram content to have true physiological effects based on the high dose needed to enter the central nervous system through the blood-brain barrier. On the other hand, some suggest that “micro-dosing” with the lower CBD doses found in many products is enough to help replace endocannabinoid deficiencies. These dosing uncertainties have yet to be clarified and confirmed scientifically. Pure isolated CBD has never been evaluated prospectively in a randomized controlled trial in the treatment of migraine, headache, or pain to date. So, its use in the treatment of pain disorders including migraine remains primarily anecdotal at this time, but we anticipate future trials will provide more objective scientific data. The FDA is currently gathering and assessing available objective scientific data in anticipation of providing general dosing guidelines and recommendations of use.

 

WHAT IS THE BEST CBD DOSE AND HOW DO I INCREASE THE DOSE?

For CBD dosing, a good general guideline of how to begin CBD dosing with a gentle titration is as follows:

-Week 1: 5-10 mg at bedtime

-Week 2: 5-10 mg twice daily

-Weeks 3-4: 5-10 mg three times daily

-Weeks 5 onwards: 20 mg three times daily

 

SAFETY AND SIDE EFFECTS

CBD is generally very well tolerated, and pure CBD is not felt to be sedating. Actually, low to moderate doses are often more alerting.62 Early anecdotal literature involved CBD with sedating components (full spectrum products) including trace THC, other cannabinoids, and terpenes. For example, myrcene is a terpene often attributed to the “couch lock” phenomenon of some cannabis chemovars (strains). So, the sedation was not from the CBD, but actually from these other associated components. More recent studies (up to 600 mg pure CBD) have reported no sedative side effects.

 

There is one FDA approved form of CBD called Epidiolex, and these trials are what most of the known CBD safety data comes from. This is a purified cannabis derived form of CBD which was FDA approved in June of 2018 for some forms of refractory pediatric epilepsies.63 Dosing ranges from 5 to 20 milligrams per kilogram body weight total daily dose, which is divided between a morning and evening dose. These does are significantly higher than any form of over the counter non-prescription forms of CBD commonly sold. CBD is metabolized (broken down) in the liver. So, patients with liver disease many need to be more cautious with their dosing. In the Epidiolex studies, there was a slight elevation in liver enzymes in some patients. However, the vast majority of these liver enzyme elevations were in patients using the highest 20 milligram per kilogram daily dose and particularly when CBD was also being used with other anti-seizure medications, especially valproate and clobazam. This risk was much lower in patients outside of these categories. None the less, caution should be used when CBD is used with other medications that are metabolized by the same liver enzyme systems to avoid causing high or low levels of other medications. For example, high doses of CBD (such as those in the Epidiolex trials) may increase levels of certain medications such as warfarin, macrolide antibiotics, calcium channel blocker blood pressure medications, benzodiazepines, cyclosporine immunosuppressants, sildenafil, antihistamines, antidepressants, antipsychotics, antiretrovirals (such as HIV meds), and some antiseizure medications (such as clobazam), to name a few. With that said, the more commonly used doses bought over the counter are nowhere near the high doses of CBD in Epidiolex, so the clinical relevance of CBD use with these liver interactions is unclear at much lower doses. For example, Sativex studies (a whole plant CBD rich sublingual spray) found no interactions with liver enzyme systems with 40 mg CBD. The bottom line is that there are still many uncertainties so it is better to use caution until future studies can help clarify these questions.

 

In the Epidiolex studies, the most common adverse effects in a minority of patients were somnolence, lethargy, drowsiness, fatigue, diarrhea, decreased appetite, and nausea/vomiting. However, these side effects were in patients who were also using other anti-seizure medications (virtually all of which have drowsiness as a universal side effect). In addition, Epidiolex is about 98% pure CBD, but still contains 0.15% or less of THC, traces other cannabinoids and terpenes at a dose of 10 milligrams per kilogram per day. Therefore, these side effects are most likely to be related to these other factors rather than from the CBD content itself.

 

DIFFERENCES IN CBD PRODUCT TYPE, QUALITY, AND SAFETY

CBD has a wide variety of formulations from oral (primarily oils), tinctures, vaporization, and topical creams. Full spectrum or “whole plant” oral CBD products are the most popular. They are most likely to provide the “entourage effects” of cannabis. They contain everything the cannabis plant contains including CBD, trace THC (should be ≤0.3% per Federal law), terpenes, and flavonoids. Broad spectrum CBD products can be thought of as full spectrum without the trace THC. CBD isolate products consist of CBD isolated from all plant contents, without trace THC. It is important to know that use of these products may have a risk of testing positive on a marijuana drug test (which tests for THC). Although this risk is very low and can also be influenced by differing metabolisms between people, it is still a risk to be aware of. The risk of this correlates with the presence of trace THC and this risk would be highest in full spectrum, followed by broad spectrum, followed by CBD isolate products. Lastly, there is a misconception that CBD converts into THC in the human body. This is not true, and there is no evidence of this happening in the human body, and actually more evidence that it does not happen.62 This notion was based on an old lab-based experiment which involved acids and conditions which are not reflective of normal human physiology.

 

CBD products chosen should include independent 3rd party laboratory testing for content and quality. The reason is because there are so many CBD companies and products, and many of them are of low quality. In 2017, there was a study published in the Journal of the American Medical Association (JAMA) which evaluated 84 CBD products analyzed from 31 different companies, including 40 oils, 24 vaporization liquids, and 20 tinctures.64 Only about 30% of the products were labeled accurately with what they claimed to contain, while about 70% of the products were inaccurately labeled based on actual CBD content (43% had higher than advertised CBD, 26% had lower than advertised CBD). In addition, 21.4% had high levels of THC, above legal limits.

 

Another study looked at 13 CBD products tested across Los Angeles and New Jersey.65 Five of them (almost half) had no traceable CBD, and only 1 had an accurately advertised amount of CBD! Two had high THC (3 mg), 1 CBD gel cap product was contaminated with a deadly strain of E. Coli (shiga toxin), and 2 had potentially dangerous levels of ethanol.

 

In 2017, 5 patients in Utah developed seizures, confusion, coma, and hallucinations with a labeled “CBD” product, and 52 patients were harmed through 2018 with this product. This “CBD” product actually contained a synthetic cannabinoid and no CBD at all. The International Cannabis and Cannabinoid Institute in the Czech Republic assessed 29 CBD products and found that 69% exceeded the recommended levels of polycyclic aromatic hydrocarbons. These are known carcinogens and genotoxic mutagens according to International Agency for Research on Cancer. Unregulated CBD products may contain pesticides or heavy metal contamination as well.

 

CONCLUSIONS

In summary, CBD shows analgesic and anti-inflammatory effects in scientific and animal models, but there is limited data involving human studies. However, this should be changing soon now that CBD is federally legal with easier access to research. None the less, there may be a wide variety of tremendous therapeutic potential to be harnessed. Non-FDA approved forms of CBD may have inconsistent levels of CBD, THC, and contamination. Therefore, non-FDA approved forms of CBD should be from companies using independent 3rd-party lab analysis to confirm quality and contents until FDA regulations are available. It is important to know that CBD involves drug interactions with some common liver enzyme metabolism systems, but dosing threshold to interfere with other medications being metabolized in these same pathways is unclear and needs to be further clarified.
