Cafergot

Cafergot is a combination of Ergotamine plus caffeine. Cafergot is used to treat migraine headaches and cluster headaches.

How Cafergot works

The active ingredient in Cafergot, Ergotamine, works to narrow blood vessels in the brain. This is thought to reduce the throbbing nature of the headaches. The caffeine increases the effects and the absorption of the medication. Caffeine also narrows the blood vessels.

Forms of Cafergot available to treat migraines

Cafergot is available in:

  • Tablets
  • Suppositories

Some migraine medications come in formulations that don’t require swallowing because many people with migraines suffer from nausea and vomiting and are unable to digest medications orally. There are other medications, such as Migranal and D.H.E.-45, that combine the active ingredients of Ergotamine and caffeine.
