Made for migraines?
Migraine prophylaxis is challenging because all medications that are commonly used have side effects that often limit patient adherence. Tricyclic antidepressants (dry mouth, dizziness and weight gain), beta-blockers (fatigue, decreased exercise tolerance), valproate (weight gain and fatigue), and topiramate (parasthesias and mental slowing) all have troubling side effects. Riboflavin is a vitamin with evidence of effectiveness for migraine prophylaxis. It is extremely well tolerated. In a recent study in children with migraines, Talebian et al. studied 90 children with migraines who were randomized to three groups (200 mg of riboflavin a day, 100 mg of riboflavin a day, or placebo) after observation during a 1-month baseline period.5 There was a significant reduction in migraine frequency and duration in patients receiving 200 mg of riboflavin daily, compared with placebo. Rahimdel et al. published an interesting study comparing high-dose riboflavin with valproate for migraine prophylaxis. A total of 90 patients were randomized to receive 400 mg of riboflavin or 500 mg of valproate over a 12-month study.6 Both treatments resulted in marked reduction in frequency, duration, and severity of migraines (not statistically significantly different from each other). The reduction in migraine frequency for the riboflavin group was from 9.2 headache days per month to 2.4. The American Academy of Neurology rates the level of evidence for riboflavin as B.
