Eletriptan treats migraine headaches. For best results, take it at the first sign of a migraine. Do not take more than recommended daily and weekly amounts as this may result in rebound headaches.

Eletriptan Overview


Eletriptan is a prescription medication used to treat migraine headaches once they have started. Eletriptan belongs to a group of drugs called selective serotonin receptor agonists or "triptans", which reduce swelling of blood vessels surrounding the brain. This swelling is associated with the headache pain of a migraine attack. Eletriptan blocks the release of substances from nerve endings that cause more pain and other symptoms like nausea, and sensitivity to light and sound.

This medication comes in tablet form to be taken at the first sign of a migraine headache.  A second tablet can be taken after 2 hours if needed.

Common side effects of eletriptan include dizziness, nausea, and weakness.
