Buy sumatriptan tablets online

Sumatriptan is a medication that can help to treat symptoms of migraines and cluster headaches. It is suitable to use when painkillers or non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen have not relieved your symptoms. It belongs to a group of medicines known as triptans or serotonin (5-HT1) agonists. You can take this medicine as soon as your migraine or cluster headache has started. Sumatriptan is only available on prescription. Speak to your doctor to see if Sumatriptan is suitable for you. 


How sumatriptan tablets work

Sumatriptan belongs to a group of medicines called triptans which are used to treat symptoms of migraines. It is thought that migraines are caused by the temporary widening of blood vessels in the head. Sumatriptan is believed to reduce the widening of these blood vessels, which helps to reduce symptoms of migraines. This is not a preventative medication and should only be taken when the migraine starts. Sumatriptan usually starts to work within 30-60 minutes. 



Always take this medicine exactly as described by your doctor. The recommended dose for adults is 50mg in the event of a migraine attack. Some patients will require a dose of 100mg - check with your doctor before taking a higher dose. This product is NOT recommended for children under the age of 18 and the elderly.



Take the tablet with water, preferably, as soon as possible after onset of the migraine attack. Do NOT chew or crush or crush the tablets. Speak to your doctor if your dose is too weak or too strong.


Duration of treatment

If symptoms are not reduced after the first dose, you must not take a second dose or the same attack. In the event of a subsequent attack, Sumatriptan can be taken again. If, after the first dose, your symptoms are reduced, but then return you may take a second and third dose, provided you wait at least 2 hours between doses. You must NOT take more than 300mg of Sumatriptan in any 24-hour period. DO NOT TAKE MORE THAN THE RECOMMENDED DOSE.


Can Sumatriptan cause side effects?

Like all medicines, Sumatriptan can cause side effects, although not everybody will experience them. Some symptoms may be caused by the migraine itself. Common side effects include:

  • Feeling sick (nausea) or being sick (vomiting)

  • Tiredness or drowsiness

  • Dizziness, feeling weak or getting hot flushes

  • Temporary increase in blood pressure

  • Shortness of breath

  • Aching muscles

Check the patient information leaflet for a full list of possible side effects.

Advice & Guides

Can I take two painkillers at once?

Sometimes when you take painkillers you find that although they make your headache, backache, or whatever your aches and pains you’re trying to treat a bit better, they don’t quite do the job.

This is when you might consider picking up another painkiller to try to kick that pain to the curb. But how do you know if this is safe? Can you take more than one painkiller at once?

If you’ve ever looked into your medicine cabinet and asked yourself one of these questions then you’ve come to the right place.

Frequently Asked Questions

What is a cluster headache?

Cluster headaches are a rare form of headache that occurs in clusters for around a month or 2 around the same time of year.

They can cause intense pain around one eye and can often be experienced with other symptoms such as watering or redness around the eye and a blocked or runny nose.

Conventional pain relief doesn’t usually treat the symptoms of cluster headaches, but your doctor or prescriber would be able to provide treatments to ease the pain.

What is a migraine?

A migraine is when you have a severe throbbing pain on one side of the head, but some people may find that the pain affects the area behind the eyes, back of the head and the neck, too. Symptoms like nausea, vomiting and an increased sensitivity to light or sound are typically signs that your headache is a migraine. Migraines are a relatively common health condition in the UK and they usually begin in early adulthood. They affect around 1 in 5 women and around 1 in every 15 men.

Do I need a prescription for this medication?

You do need a prescription for this medication in the UK.

Our healthcare professionals can provide prescriptions if they think this treatment would be right for you and your condition.

When you click the button which reads “Start Consultation” at the top of this page, you’ll see a short questionnaire set up by our healthcare team which is designed to help them understand your medical needs.
