Sumatriptan is a medicine used to treat migraines. Sumatriptan helps relieve symptoms such as headache, pain, nausea, vomiting and sensitivity to light. Sumatriptan tablets are prescribed when painkillers fail to relieve migraine symptoms.
Sumatriptan is a type of medicine known as a triptan or serotonin receptor agonist. When you have a migraine, your blood vessels become wider. By using sumatriptan to stimulate the release of serotonin, this narrows your blood vessels to help relieve your migraine. Sumatriptan also reduces pain signals in the brain. However, sumatriptan cannot be taken to prevent migraines.
Sumatriptan normally works within 30 minutes after you take your first tablet. If you don’t feel better after two hours, then you can take a second tablet. The effects of sumatriptan can last around 24 hours so do not take more than two doses in 24 hours. If sumatriptan is not working after two doses, you should contact your doctor for further advice.
Sumatriptan is effective for upto 24 hours. If you do not feel your migraine is getting better after two doses of sumatriptan in 24 hours, then speak to your doctor for advice.
The active ingredient in Sumatriptan is sumatriptan.
The inactive ingredients in Sumatriptan are lactose monohydrate, hypromellose, microcrystalline cellulose, croscarmellose sodium, magnesium stearate, hypromellose, and titanium dioxide (E171). The 50 mg film-coated tablets also include triacetin and red iron oxide (E172).

Your dose of sumatriptan will be decided by a doctor depending on how bad your migraines are and how well you have responded to treatments in the past. For adults aged 18 to 65 years old, you take one 50 mg sumatriptan tablet as soon as you feel a migraine starting. You may need to take a higher dose if your migraines do not improve. Sumatriptan isn’t normally recommended for adults over 65 years old.
Always use sumatriptan as your doctor or pharmacist tells you to. Swallow one sumatriptan tablet whole with a glass of water as soon as you feel a migraine starting. Do not crush or chew sumatriptan tablets. If your first dose does not relieve your migraine symptoms completely, then you can take a second dose two hours later. You should not take more than two doses in 24 hours. If you don’t feel better after two doses, contact your doctor for advice.
