What is Sumatriptan?
It is the generic version of the drug Imigran used to treat migraines. Triptans are prescribed for migraine sufferers to help cope with the changes in the brain caused by migraines. By contracting blood vessels, triptans are able to stabilise brain chemicals and alleviate the pain brought on by migraines.
Other forms of this medicine include imigran nasal spray and an injection.
Migraine Treatment with Sumatriptan
Sumatriptan cannot cure cluster headaches or migraines, neither can it prevent the oncoming of these afflictions. However, it is very effective in lessening the pain caused by these conditions, alleviating the symptoms and allowing you to go about your everyday life without interruption from chronic pain. While it is not classed as a painkiller, the medicine can be used as one if non-steroidal anti-inflammatory drugs (NSAIDs) or painkillers have not effectively lessened your symptoms.
This medicine stabilises several chemical changes within the brain during a migraine attack, reducing your symptoms.
Changes in the brain which cause migraines are thought to involve the widening of blood vessels within the brain. Sumatriptan contains the active ingredient sumatriptan succinate, which causes your brain's blood vessels to contract, thus alleviating the symptoms of a migraine. By stimulating the serotonin receptors in your brain, it causes the surrounding muscles to contract, lessening the pain of a migraine attack.
Sumatriptan: Where to buy
You can purchase this medicine when you have a prescription from your doctor.
Sumatriptan 50mg or 100mg doses are available to be purchased at our online pharmacy. Packets come with either 6 tablets, 12 tablets, 18 tablets or 24 tablets. You can buy it from a pharmacy for migraine relief without a prescription, but only if you have been diagnosed with migraines in the past.
Who can take Sumatriptan tablets?
You should not take Sumatriptan tablets if you suffer from any of the following conditions or allergies:
- You have high blood pressure
- You have recently used ergotamine or similar medicines or MAO inhibitors
- Any heart conditions (such as heart attacks, angina or tachyarrhythmia)
- You have seizures or fits
- You are allergic to Sumatriptan, Tripans 5-HT1, antimigraine agents, or any other ingredients
- A severely reduced liver function or liver disease
Sumatriptan is not believed to be harmful to take during pregnancy, although there is little research to prove this, so you should always talk to a doctor about the possible problems as other medicines may be safer to use.
It is normally safe to take if you are breastfeeding. Speak to a doctor if your baby was premature or has any health problems. You should also talk to your doctor about Sumatriptan if you are trying to get pregnant.
You are not advised to take Sumatriptan tablets if you intend to drive or operate machinery. Migraines often cause drowsiness and dizziness, so you should avoid driving a car or operating any type of machinery until you feel better.
Sumatriptan can also have an adverse effect on anybody who is taking antidepressants; if you are taking antidepressants, you should consult your doctor before you start taking this medication.
You can eat and drink as normal while taking Sumatriptan as alcohol does not affect the medicine. However, during any headache attack it is always best to avoid any alcohol as it can sometimes be the trigger for a migraine or cluster headache.
If you have any doubt at all about any of the above conditions, you should speak to your doctor or pharmacist before taking the medicine.
Possible Side Effects
Like all medicines, Sumatriptan can cause side effects, although most people experience none at all, or only minor ones.
These usually mild and do not last long, but can include: nausea and/or vomiting, dizziness or feeling unsteady on your feet, tiredness, feeling hot or cold, or your face flushing red. If any of these issues bother you or last for more than a few days, you should consult your doctor or pharmacist.
For the full list of potential adverse effects, please refer to the patient information leaflet inside your medicine's packaging.
In very rare cases, people can have a severe allergic reaction to Sumatriptan. More information can be found about this under the 'Side Effects' tab on this page, but if you experience any of the symptoms listed as a severe allergic reaction, you may require treatment in hospital and should either call 999 or go to A&E, immediately.
All of our doctors and Pharmacists follow NICE guidelines when prescribing Sumatriptan 500/100mg tablets.
Sumatriptan tablets are only used to treat migraines and are available as a prescription-only medicine (POM) as either 50mg or 100mg tablets. Your first dose should be taken only when the pain has actually started, not before, as this can lead to symptoms of “aura”, which are the temporary warning symptoms before a migraine. Do not take Sumatriptan as a preventative measure against the onset of migraines.
Sumatriptan 50mg tablets are the regular starting dose for most people who experience migraine pain; this dosage should be sufficient to relieve most of the symptoms brought on by migraines, without needing to repeat the dose. If you suffer from severe migraines, or 50mg is not effective enough, you may prefer to try Sumatriptan 100mg strength tablets.
You should swallow Sumatriptan tablets whole and take them as soon as possible after your migraine pain has started. This will help to reduce the symptoms in the shortest period of time. The medicine should begin to work between 30 and 60 minutes after being taken, but if required the dose can be repeated after a minimum of 2 hours.
As with any medicine you buy, you should always read the information leaflet thoroughly before taking any dose. Do not take more than the prescribed amount of Sumatriptan within the same 24 hours.

Sumatriptan Warnings and drug interactions
Sumatriptan is generally considered to be a safe form of medication; it has been used for many years and has proven an effective way of tackling the symptoms of migraines.
It should be noted that Sumatriptan (Imigran) can cause your blood vessels to narrow, temporarily. For this reason, people who have had problems with poor circulation, a history of angina, heart attacks, strokes or mini-strokes should not take Sumatriptan. In rare situations, Sumatriptan can trigger serious heart problems even in people who have never had circulation problems.
You should check with your GP before taking Sumatriptan if you are a heavy smoker, a woman who has had the menopause or a man over the age of 40.
Migraines are, in some rare cases, associated with loss of vision, loss of speech and paralysis.
You should always see a GP for a diagnosis before you self-medicate for a headache. You should not take Sumatriptan in any of the below instances:
- When headaches are different from previous ones or they show new symptoms
- When headaches are more frequent and last longer
- When headaches start for the first time over the age of 40
Do not take Sumatriptan tablets if:
- You have high blood pressure
- You have severely reduced liver function
- You are allergic to Sumatriptan or any of the ingredients

Pregnancy and breastfeeding
