More information
Sumatriptan is primarily prescribed as a first-line intervention for the acute relief of migraine headaches, with or without aura, and is also an essential treatment for the intense pain associated with cluster headaches. It is most effective when taken at the very first sign of a migraine headache, helping to stop the progression of symptoms and allowing patients to return to their daily activities sooner.

Sumatriptan is a specific type of medicine called a triptan, which is used to treat the symptoms of a migraine attack once it has started. Unlike standard painkillers like paracetamol or ibuprofen, it is specifically designed to target the biological changes in the brain that cause a migraine, such as the widening of blood vessels and the release of inflammatory substances.
The active ingredient in this medication is sumatriptan (sometimes known as sumatriptan succinate). Each tablet also contains inactive excipients such as lactose monohydrate and microcrystalline cellulose, which help the tablet hold its shape and dissolve correctly in your system.
Many patients report that Sumatriptan is a "life-saver" for managing debilitating migraines that do not respond to over-the-counter analgesics. According to the Migraine Trust, approximately 10 million people in the UK live with migraine, and access to effective triptans is a key factor in reducing workplace absenteeism and improving quality of life.
It is essential to read the Patient Information Leaflet (PIL) provided with your medication before use. You can access the official Sumatriptan PIL via the EMC website for detailed data on ingredients, storage, and safety.
Sumatriptan works by stimulating serotonin (5-HT1) receptors in the brain, which causes the temporarily widened blood vessels to narrow back to their normal size. This process, known as vasoconstriction, reduces the throbbing pain and helps alleviate associated symptoms like nausea and sensitivity to sound (phonophobia).
You should take one Sumatriptan tablet as soon as you feel a migraine headache beginning, though it remains effective if taken at any point during the attack. Do not take the tablet during the "aura" phase (visual disturbances) if you have not yet developed a headache, as it is only intended to treat the pain phase.
The standard starting dose for adults is a single 50mg tablet, although some patients may require 100mg for effective relief. If your symptoms improve but then return, you can take a second dose after at least 2 hours, but you must never exceed 300mg in any 24-hour period.
Common side effects are usually mild and short-lived, including feelings of heaviness, pressure, or tightness in the chest and throat. Other reported effects include:
- Dizziness or drowsiness.
- Facial flushing or feeling hot.
- Nausea and dry mouth.
- Tingling sensations (paraesthesia).
Sumatriptan is not suitable for everyone and should be avoided by individuals with a history of heart disease, stroke, or uncontrolled high blood pressure. If you are a smoker, over 40 (male), or post-menopausal (female), a cardiovascular assessment may be required before starting treatment to ensure your safety.
Sumatriptan is often the first triptan prescribed in the UK due to its extensive safety record and lower cost compared to newer triptans. While medications like Rizatriptan may work slightly faster for some, Sumatriptan remains the "gold standard" for the majority of migraine sufferers.

Can I buy Sumatriptan over the counter?
Yes, Sumatriptan 50mg is available over the counter as 'Imigran Recovery' for those previously diagnosed with migraine, but buying it via a prescription service like Mail My Meds is often more cost-effective for regular users.
How many Sumatriptan can I take in a day?
The maximum dose for Sumatriptan tablets is 300mg within a 24-hour window, provided there is at least a 2-hour gap between doses. If the first tablet does not work at all, you should not take a second one for the same attack.
What if my migraine is not responding to Sumatriptan?
If Sumatriptan is ineffective after several attempts, our prescribers may recommend switching to a different triptan or investigating preventative treatments. It is important to discuss persistent symptoms with a healthcare professional to rule out medication-overuse headaches.
