Eletriptan (Relpax)

Eletriptan is used to treat the symptoms of migraine headaches (severe throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound and light). Eletriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels in the brain, stopping pain signals from being sent to the brain, and blocking the release of certain natural substances that cause pain, nausea, and other symptoms of migraine. Eletriptan does not prevent migraine attacks or reduce the number of headaches you have.
