Migraines and cluster headaches are severe recurrent headaches. Medications to treat them fall under a number of different categories. These include triptans and ergot alkaloids for abortive therapy. For preventative therapy, a number of different drug classes are available, including beta blockers, predisone, antidepressants, lithium, antiseizure medications and others.
Migraines are severe, recurrent headaches that usually affect one side of the head. Many times, symptoms include visual affects like auras or scotomas (a blank patch in the field of vision). Treatment for visual effects of migraines includes a number of drugs used to treat a migraine as a whole, as well as adequate sleep and exercise.
