Generic Name: sumatriptan (SOO-ma-TRIP-tan)
Brand Name: Imitrex
Imitrex spray is used for:
The treatment of migraine headaches with or without aura (eg, flashing lights, wavy lines, dark spots). It may also be used for other conditions as determined by your doctor.
Imitrex spray is a serotonin 5-HT 1 receptor agonist ("triptan"). It works by narrowing blood vessels in the brain, which helps to relieve migraines.

- you have uncontrolled high blood pressure or severe liver problems
- you have certain types of migraines (eg, hemiplegic, basilar)
- you are taking or have taken a monamine oxidase inhibitor (MAOI) (eg, phenelzine) within the past 14 days
- you have used certain other migraine medicines within the past 24 hours (eg, an ergot derivative [eg, dihydroergotamine, methysergide], another serotonin 5-HT 1 receptor agonist [eg, eletriptan, rizatriptan])
- you are taking sibutramine
Contact your doctor or health care provider right away if any of these apply to you.
