Imitrex

Generic name: Sumatriptan succinate

Why is Imitrex prescribed?

Imitrex is prescribed for the treatment of a migraine attack with or without the presence of an aura (visual disturbances, usually sensations of halos or flickering lights, which precede an attack). The injectable form is also used to relieve cluster headache attacks. (Cluster headaches come on in waves, then disappear for long periods of time. They are limited to one side of the head, and occur mainly in men.)

Imitrex cuts headaches short. It will not reduce the number of attacks you experience.

Most important fact about Imitrex

Imitrex should be used only to treat an acute, classic migraine attack or a cluster headache. It should not be used for certain unusual types of migraine.

How should you take Imitrex?

Imitrex should be taken as soon as your symptoms appear, but may be used at any time during an attack. It is available in three forms: injection, tablets, and nasal spray.

Imitrex injection is administered just below the skin with an autoinjector (self-injection device). Choose a site where the skin is thick enough to take the full length of the needle (1/4 inch). Avoid injecting Imitrex into a muscle or a vein. Your doctor should instruct you on how to use the autoinjector and how to dispose of the empty syringes. You should also read the instruction pamphlet that comes with the medication.

You can take a second injection if your headache returns; however, never take more than 2 injections within 24 hours, and be sure to wait 1 hour between doses.

Imitrex tablets should be swallowed whole, with liquid. If you have had no relief 2 hours after taking Imitrex Tablets, you may take a second dose of up to 100 milligrams, if your doctor advises it. If the headache returns, you may take additional doses at intervals of at least 2 hours. You should not take more than 300 milligrams in one day. If your headache returns after you have had an Imitrex Injection, you may take single Imitrex Tablets, at intervals of at least 2 hours, up to a maximum of 200 milligrams in a day.
