What is Sumatriptan?
Sumatriptan (otherwise know under the brand name Imigran) is a popular treatment for migraines and belongs to a class of medicines known as ‘triptans.’ Triptans work differently to painkillers as they work by stimulating 5HT (serotonin) receptors in the brain to reverse the temporary widening of the blood vessels there which are though to contribute to a migraine attack. As well as treating the cause of the migraine, they also help to reduce associated symptoms such as headache, nausea, vomiting and sensitivity to light or sound.
Sumatriptan should be taken when lifestyle changes and analgesics such as paracetamol, aspirin, ibuprofen, (or those analgesics combined with codeine) haven’t worked. It cannot be used to prevent a migraine, only to treat one.
