Imitrex (Imigran, Sumatriptan) Information
Imitrex (Imigran) tablets.

Common uses and directions for Imitrex (Imigran)
Imitrex (Imigran) tablets contain the active ingredient
sumatriptan succinate. Imitrex belongs to a group of drugs called serotonin
agonists.
Imitrex tablets are used to relieve a migraine attack.
Imitrex should not be used to prevent migraine attacks from occurring.
Imitrex tablets may be used for migraine headaches with or without what is
known as 'aura'. It is thought that migraine headache is due to widening of
certain blood vessels in the head. Imitrex tablets work by making those
vessels normal again and ease the symptoms of migraine. Imitrex tablets do
not work in other types of headache which are not a migraine. Imitrex
tablets are not addictive.
The recommended starting dose for adults is 50 mg, however
you may need to have your dose of Imitrex tablets increased to 100 mg. If
the first Imitrex tablet helps your migraine, but the migraine comes back
later, you may take another Imitrex tablet. Do not take more than 300 mg of
Imitrex tablets in any twenty-four hours.
