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. Eletriptan (Generic) is available for purchase. 

Eletriptan comes as a tablet to take by mouth. It is usually taken at the first sign of a migraine headache. 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. Your doctor will tell you the maximum number of tablets you may take in a 24-hour period. 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 another medical facility where you can be monitored for serious reactions. Call your doctor if your headaches do not get better or occur more frequently after taking eletriptan. If you take eletriptan more often or for longer than the recommended period of time, your headaches may get worse or may occur more frequently. You should not take eletriptan or any other headache medication for more than 10 days per month. Call your doctor if you need to take eletriptan to treat more than three headaches in a 1-month period. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
