Sumatriptan is used to treat migraines and cluster headaches.
Take sumatriptan as directed when your symptoms first start.
Take the tablets with a large glass of water.
Inject the injection under the skin as directed.
If your symptoms get better, but then return, you can take another dose after 1 hour (injection) or 2 hours (tablet).
If sumatriptan does not help, do not take any further doses for the same attack, as it is unlikely to work. You can still use sumatriptan for a new attack.
Do not take more than the maximum daily dose advised by your health professional.
Some medicines available without a prescription may react with sumatriptan including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.
