Imigran nasal spray contains sumatriptan, which is a medicine used to treat migraine headaches.
The active ingredient in Imigran nasal spray is a triptan called sumatriptan. This is a migraine-specific painkiller that works by making blood vessels in the brain narrower. During a migraine blood vessels dilate (widen), and by narrowing them it helps alleviate migraine symptoms.
It takes around 15 minutes for Imigran nasal spray to work.
Imigran nasal spray can alleviate migraine pain completely for 24 hours, but if symptoms do return you must leave at least 2 hours between doses. Do not use more than two 10 mg doses in 24 hours. If the spray has no effect, do not use another dose – try another type of painkiller instead and see your doctor.
Imigran nasal spray should only be used at the onset of a migraine headache. It cannot be used to treat ocular migraines (migraines involving vision loss), hemiplegic migraines (characterised by muscle weakness on one side of the body) or basilar migraines (a migraine with brainstem aura).
If over the counter painkillers do not help treat your migraines, Imigran nasal spray or other triptan medicines may be more effective. Imigran nasal spray is more effective than Imigran (sumatriptan) tablets.

You should avoid using this medication if you are allergic to sumatriptan or have previously had an allergic reaction to sulfonamide antibiotics (eg. co-trimazole). Please stop using this nasal spray and get medical attention right away if you develop these symptoms: a rash, itching, trouble breathing, severe dizziness. Stop using the medication if you have these symptoms and let your doctor know as soon as possible.
Use Imigran nasal spray as soon as you feel a migraine starting. Blow your nose first if you need to. Remove the spray out of its blister packet, and put the nozzle into one nostril as far as is comfortable, while blocking your other nostril with a finger. As you breathe in, press the plunger to spray the medicine into your nostril. Stay upright and breathe in through your nose and out through your mouth for a few seconds after application, to make sure the spray remains inside your nose.
Imigran Nasal Spray is available in either 10mg or 20mg doses. 20mg is the usual recommended dose for adults, but 10mg may be effective for some people. Adolescents aged between 12 and 17 should use a 10mg dose.

Other triptan-based medicines are also available. These include zolmitriptan and rizatriptan (Maxalt).
Alternatives to triptans include over the counter painkillers like paracetamol, aspirin or ibuprofen. There are also antiemetics like Buccastem. Some migraine medicines combine a painkiller and an antiemetic in one tablet.
