Imitrex is prescribed to relieve migraine and its associated nausea and light sensitivity. It does not prevent or reduce the number of attacks of migraine. Imitrex should not be prescribed to treat other types of headaches.
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 prescribed 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.
For many migraine sufferers Imitrex, appropriately used, has been a valuable and effective treatment in aborting attacks. Side effects are generally transient.
Some common side effects include:
- Abdominal discomfort;
