What is Sumatriptan?

The active ingredient in Sumatriptan is known as Sumatriptan Succinate, which belongs to a group of medicines called triptans (5-HT receptor agonists). Triptans are different from typical painkilling medications as they don’t just dull the pain, but actively work to reverse changes in the brain that are thought to induce a migraine attack. They also alleviate symptoms of migraines.

Why Sumatriptan?

Sumatriptan Succinate is designed to reverse the temporary widening of blood vessels in the brain. The pressure caused by the dilation of these blood vessels is thought to contribute to the onset of migraine attacks. By stimulating the brain’s serotonin receptors, Sumatriptan Succinate can treat the cause of a migraine and reduce any symptoms associated with it, like headaches, nausea and sensory sensitivity.

What is the difference between Sumatriptan and Imigran?

Imigran is the leading branded medication for migraine relief. Like Sumatriptan, it also includes the active ingredient Sumatriptan Succinate and can be used to tackle migraines at the source and reduce the symptoms involved.

Like many generic medications, Sumatriptan is medically identical to its branded counterpart but represents a more affordable and cost-effective solution to Imigran.

How to use Sumatriptan

Before taking Sumatriptan, consult the enclosed patient information leaflet. Sumatriptan is suitable for anybody over the age of 18 who is suffering with migraines.

The maximum daily dosage of Sumatriptan is 300 milligrams. This is equivalent to either six 50mg tablets a day or three 100mg capsules a day. Do not exceed more than 300mg of Sumatriptan within a 24 hour window.

Sumatriptan is not dependent on food, so you can take it with or without food alongside.

When should you take Sumatriptan?

You should consume 50mg of Sumatriptan as soon as possible once your symptoms flare up. Do not take it before any symptoms have occurred as it is not a preventative medication and will therefore not stop the migraine from occurring.

If after your first dose your symptoms are reduced, but later return, you may take a second dose at least two hours following on from your first. If the first tablet has no effect on your symptoms, do not take another dose. Contact your GP or our Patient Support Team instead on 0208 123 07 03 or at help@expresspharmacy.co.uk.

Side Effects

With most prescription medication there are risks of side effects, and the same is true of Sumatriptan. The nature of these side effects may vary from person to person.

For most people, there will be no discernable side effect to using the medication. However, one in ten people may experience adverse effects to the drug such as tiredness and drowsiness, nausea, vomiting and dizziness. A few people may also experience sensations of heaviness and short term increases in blood pressure (transient).

For more information on the side effects of Sumatriptan, consult the patient information leaflet.


All migraine medication should be taken with care in order to avoid the risk of an overuse headache. A medication overuse headache, or rebound headache, can be caused by an overuse of drugs used to treat migraines. If you feel you need to take more than ten doses of Sumatriptan a month, consult your GP for advice first.
