What is Imigran nasal spray used for?

Imigran nasal spray contains the active ingredient sumatriptan. This medicine belongs to a group of drugs called serotonin agonists.

Imigran nasal spray is used to relieve a migraine attack. It should not be used to prevent migraine attacks from occurring. Imigran nasal spray 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. Imigran nasal spray works by making those vessels normal again and eases the symptoms of migraine.

Your Imigran nasal spray does not work in other types of headache which are not a migraine.

Imigran nasal spray is not addictive.
