Frequently Asked Questions
Sumatriptan is an oral tablet medication used to treat migraines. It’s typically taken at a dosage of 50mg. Sumatriptan is taken at the start of a migraine attack in order to reduce the symptoms. It does not prevent migraine attacks, so you should not take it to try and prevent migraines.
Sumatriptan belongs to a class of medications known as Triptans. Triptans reduce the widening of blood vessels in the brain. It’s believed that migraines can be caused by the widening of blood vessels in the brain, so Triptans effectively counter this process.
You should take a Sumatriptan tablet at the start of a migraine attack. If the symptoms of that attack do not subside after taking Sumatriptan, you should not take another tablet for the same attack. If you experience another migraine attack after two hours, you may need to take a second tablet.

Some of the side effects of Sumatriptan are similar to the symptoms of a migraine attack. As you take Sumatriptan during the start of an attack, it can be difficult to tell whether you are experiencing migraine symptoms, Sumatriptan side effects or a combination of both. If you do become concerned about the side effects of Sumatriptan, you should talk to your doctor or pharmacist.
Avoiding alcohol when taking Sumatriptan is a good idea. Migraine symptoms and Sumatriptan side effects can induce tiredness, dizziness and nausea, which are all exacerbated by alcohol.
If you are prescribed Sumatriptan, you should receive a Patient Information Leaflet outlining more possible side effects as well as further warning and precautions.
