What is Imigran?

The cause of migraine attacks is not fully understood, but is thought to involve changes in the levels of chemicals in the brain. The throbbing pain of migraine headaches is a result of blood vessels in the brain widening or swelling. Imigran acts on serotonin (or 5HT) receptors that are found on blood vessels in the brain, causing them to narrow. It's also thought to inhibit the action of the trigeminal nerve. These actions relieve the headache and other symptoms that you may get with your migraine, such as feeling sick or sensitivity to light or sound.

How to take Imigran

It is best to take Imigran as soon as you feel a migraine attack coming on, although you can take it at any time during an attack. Don't use Imigran in an attempt to prevent an attack - only use it after your migraine symptoms start or at the first signs of a migraine aura. The tablets can be swallowed whole or dispersed in water before taking. If dispersed please be aware that the resulting solution has a bitter taste.

If your symptoms come back you can take a second Imigran tablet if at least 2 hours have passed since the first tablet. Don't take more than 300 mg in total in 24 hours. If the first tablet has no effect. Don’t take a second tablet or any other Imigran preparation for the same attack. Imigran can still be used for your next attack.

For further information and dosage please see the patient information leaflet.
