Compare Onzetra vs. Cafergot

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Onzetra (sumatriptan) and Cafergot (ergotamine/caffeine) are both used to treat migraines, but they have some key differences. Onzetra is a triptan that works by tightening blood vessels in the brain and stopping the release of sensory chemicals. It is available as a nasal powder that you blow into your nose using a special device. Onzetra can provide relief within 30 minutes to 2 hours and is a first-choice option for short-term migraine treatment. In contrast, Cafergot combines ergotamine and caffeine to tighten blood vessels and calm parts of the brain. It is available as an oral tablet or a rectal suppository. Cafergot is not recommended for daily or long-term use and is not safe during pregnancy. While Onzetra is only available as a brand medication, Cafergot tablets are available as a lower-cost generic. Both medications have serious side effects, but Cafergot has additional risks like fibrosis and dangerously low blood flow to the brain and limbs.
