Key takeaways
Topiramate (Topamax, Qudexy XR, Trokendi XR, Eprontia) and ergotamine/caffeine (Cafergot, Migergot) are both medications used to treat migraines, but they belong to different medication classes. Topiramate is an antiepileptic medication that can also prevent migraines, while ergotamine/caffeine is an ergot derivative and PDE inhibitor used to treat active migraine and cluster headache episodes. Topiramate is available in various forms, including tablets, capsules, and a liquid solution, and is typically taken once or twice daily. In contrast, ergotamine/caffeine is available as oral tablets and rectal suppositories, taken as needed at the onset of a headache. Topiramate comes in both branded and generic forms, while ergotamine/caffeine only comes as a generic. Common side effects of topiramate include drowsiness, weight loss, and nervousness, whereas ergotamine/caffeine commonly causes nausea. Topiramate has many drug interactions, while ergotamine/caffeine should not be taken with certain antibiotics or protease inhibitors.
