Were you looking for information about Imitrex? Imetrex is a common misspelling of Imitrex.
For people who suffer from migraine headaches, Imitrex® (sumatriptan succinate) may be prescribed to help relieve the symptoms of a migraine that has already started. During a migraine, the blood vessels in the head can expand. Imitrex works by narrowing these blood vessels and returning them to their normal state. Imitrex is designed to be taken only after migraine symptoms begin, not beforehand. The medicine comes in a tablet form, as a nasal spray, or as an injection.
