Triptans

Also known as: triptan, 5-HT1 agonists for migraine

Triptans are medicines for treating migraine attacks, and sumatriptan is the triptan covered on this site. The NHS says sumatriptan relieves symptoms of migraine but does not prevent migraines from starting. The NHS describes sumatriptan as available as tablets, a nasal spray and an injection. The NHS says most adults can take sumatriptan, that it is not officially approved for children, and that a specialist doctor may sometimes prescribe it for a child.

Mechanism of action

The NHS says migraines may be linked to temporarily widened blood vessels in the brain, and that sumatriptan narrows these blood vessels. Sumatriptan is a triptan, a type of medicine that acts on serotonin (5-HT) receptors. It is taken once a headache has started, not to prevent attacks. Taking sumatriptan with some antidepressants or St John's wort can raise the risk of serotonin syndrome, a severe side effect.
