IMIGRAN - a patient's guide

Abstract

Imigran is an effective treatment for migraine headaches. This article provides an overview of the product.

DRUG NAME: Sumatriptan succinate

USE: Migraine/ headache relief

This medicine belongs to a group of drugs called serotonin agonists, which is used for the relief of pain associated with migraine and cluster headache.

Migraine is thought to be due to the widening of certain blood vessels in the head, where Imigran works via 5-HT1 receptors which are responsible for making these vessels normal again. This effect usually relieves migraine within 30 minutes in a high proportion of sufferers.

CAUTION:

  • Heart disease (family history) or previous heart attack
  • Ergotamine preparations (used for prevention of migraine)
  • Liver and kidney impairment
  • High blood pressure

  • History of stroke, epilepsy or brain tumour

Tell your doctor immediately if you feel/have: heaviness/ tightness of chest (wheeze), abnormal heartbeat, a fit/convulsion, or you collapse, develop skin rash, or swollen face/eyelids.
