What is sumatriptan (Imitrex, Imitrex Nasal, Onzetra Xsail)?
Sumatriptan is a headache medicine that narrows blood vessels
around the brain. Sumatriptan also reduces substances in the body that

Sumatriptan is used to treat migraine headaches in adults. Sumatriptan
will only treat a headache. This medicine will not prevent headaches or
reduce the number of attacks.
Sumatriptan should not be used to treat a common tension headache
or a headache that causes loss of movement on one side of your body.
Use this medicine only if your condition has been confirmed by a doctor
as migraine headaches.
Sumatriptan may also be used for purposes not listed in this medication
guide.
