Imitrex, also known by its generic name sumatriptan, is a medication used to treat migraines. Imitrex relieves pain, headache, and other symptoms including nausea, vomiting, and sensitivity to light and sound. This medication belongs to a class of drugs known as triptans. Triptans affect your serotonin levels and narrows the blood vessels in the brain. This may also relieve pain by affecting certain nerves in the brain. Imitrex tablets come in 50 and 100mg doses.
Take Imitrex as soon as you feel a migraine coming on. If your headache does not go away, use a second dose if it has been at least 2 hours since your first dose.
There are sumatriptan injections that can be injected by a doctor to treat cluster headaches (severe headaches usually on one side of the head or around the eye).
Along with the tablet form, there is also an intranasal version of Imitrex. The doses are administered in a single spray in one nostril. The maximum dose per day is 40 mg in 24 hours.
