Generic Name: eletriptan (EL-e-TRIP-tan)
Brand Name: Relpax
Eletriptan is used for:
Treating acute migraine headaches. It may also be used for other conditions as determined by your doctor.
Eletriptan is a 5-HT1 agonist. It works by narrowing the blood vessels in the brain and thereby reducing pressure and pain in the brain. A migraine headache is thought to be caused by widened blood vessels exerting pressure on the brain.
Do NOT use eletriptan if:
- you are allergic to any ingredient in eletriptan
- you have uncontrolled high blood pressure
- you have hemiplegic or basilar migraine headaches or severe liver problems
- you have a history of heart problems, ischemic heart disease (eg, angina), a heart attack, a stroke, a transient ischemic attack (TIA, mini-stroke), brain blood vessel problems, or other circulation or blood vessel problems (eg, ischemic bowel disease)
- you have taken certain azole antifungals (eg, ketoconazole, itraconazole), certain HIV protease inhibitors (eg, ritonavir, nelfinavir), certain macrolide antibiotics (eg, erythromycin, clarithromycin, troleandomycin), nefazodone, or telithromycin within the last 72 hours
- you have taken an ergot alkaloid (eg, ergotamine) or another 5-HT1 agonist (eg, sumatriptan) within the last 24 hours
Contact your doctor or health care provider right away if any of these apply to you.
