Eletriptan treats migraine headaches by narrowing blood vessels around the brain. It cannot be used to treat other types of headaches. It is intended to treat headaches that have already begun, not prevent future potential headaches. Eletriptan is not meant to be taken by patients under age 18.
Take eletriptan as soon as migraine symptoms begin. If migraine doesn’t subside, or returns, take second tablet 2 hours after the first. Do not take more than 80 mg of eletriptan in 24 hours. Do not use more than recommended dose. Do not take medication for longer than 10 days in a month.
Inform your doctor of your medical conditions and medications you take before use. Do not use eletriptan if you have cardiovascular issues, hypertension, severe liver disease, ischemic bowel disease, or headaches that feel different from migraines. Do not take eletriptan within 24 hours before or after another migraine headache drug. Do not take eletriptan within 72 hours before/after taking itraconazole, ketoconazole, nefazodone, clarithromycin, ritonavir, or nelfinavir.
Cease use, find help, and inform physician if you experience serious side effects such as: allergic reaction, uneven/too fast or slow pulse, sudden severe stomach pain, fever, bloody diarrhea, numbness and tingling, blueness in fingers and toes, tightness/heaviness in legs, symptoms of heart attack or stroke, symptoms of high blood pressure or too much serotonin. Other common side effects include dizziness, drowsiness, nausea, fatigue, and weakness. Eletriptan can interact with medication used to treat depression and other psychiatric disorders, narcotics, and nausea/vomiting medication.
