Eletriptan (patient information)

Why is this medication prescribed?

Eletriptan is used to treat the symptoms of migraine headache (severe throbbing headache that sometimes comes along with nausea and sensitivity to sound and light). Eletriptan is in a class of medications called selective serotonin receptor agonists. It works by reducing swelling of 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.

How should this medicine be used?

Eletriptan comes as a tablet to take by mouth. It is usually taken at the first sign of a migraine attack. If your symptoms improve after you take eletriptan but return after 2 hours or longer, you may take a second tablet. However, if your symptoms do not improve after you take eletriptan, do not take a second tablet before calling your doctor. Do not take more than two eletriptan tablets in any 24-hour period. Call your doctor if you need to take eletriptan more than three times a month. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take eletriptan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

You may take your first dose of eletriptan in a doctor's office or other medical facility where you can be monitored for serious reactions.
