The National Headache Foundation exists to enhance the medical treatment of headache. It serves as a resource for people who suffer from headaches, physicians, allied health professionals, and the public.
Several types of migraine drugs can help prevent the piercing pain of migraines, including:
Beta-blockers such as Inderal (propanalol) and Toprol (metoprolol), which relax blood vessels
Calcium channel blockers such as Cardizem (dilatizem) and verapamil, which reduce the amount of narrowing (constriction) of the blood vessels
Antidepressants such as amitriptyline and nortriptyline -- tricyclic antidepressants which have been shown to be effective in preventing migraines.
