Although it can't prevent migraines, rizatriptan benzoate (Maxalt®) is a useful drug for treating migraines once they start. This prescription medication is approved for use in adults as well as children as young as six years of age. In clinical studies, 60 percent to 77 percent of people with migraines had no or mild pain within two hours of taking Maxalt tablets, compared to only 23 percent to 40 percent of people who did not take the drug.
Rizatriptan comes in regular tablets and as orally disintegrating tablets that dissolve in the mouth quickly. Regardless of the form being used, it should be taken as soon as possible once the migraine starts.
