What this medicine is used for
Sumatriptan is used to relieve a migraine attack. This medicine may be used for migraine headaches with or without what is known as ‘aura’.
Sumatriptan belongs to a group of drugs called serotonin agonists.
How it works
It is thought that a migraine headache is due to widening of certain blood vessels in the head. Sumatriptan works by narrowing the affected vessels, to ease the symptoms of migraine.
This medicine does not work in other types of headache which are not a migraine. It should not be used to prevent migraine attacks from occurring.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.

The effectiveness of this medicine has not been established in adolescents between 12 and 17; and the safety and effectiveness of this medicine in children under the age of 12 years has not been established.

How much to take
Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines. If you have liver problems you may be prescribed a lower dose.
The recommended starting dose for adults is 50 mg, however your dose may be increased to 100 mg if needed.
If the first tablet helps your migraine, but the migraine comes back again later, you may take another tablet.
If the first dose has not provided any relief from your symptoms, do not take any more sumatriptan for this attack. Your doctor should review your treatment to check if this medicine is still appropriate for you.
Do not take more than 300 mg of this medicine in any 24 hours.
Six pink (50 mg strength) or three white (100 mg strength) tablets contain 300 mg of sumatriptan.
You may take your usual headache relief medication provided it does not contain ergotamine, methysergide, naratriptan or zolmitriptan. If you are not sure what to do, ask your doctor or pharmacist.
How to take it
Swallow the tablets whole with a glass of water. Do not crush or chew this medicine as it has a bitter taste.
When to take it
It is best to take this medicine:
when the migraine headache begins, or
when other symptoms of the migraine begin, such as nausea (feeling sick), vomiting or your eyes becoming sensitive to light.
If you take this medicine later during the migraine attack, it will still work for you. Do not take this medicine before the above symptoms occur.
It does not matter if you take it with or without food.
How long to take it for
This medicine is not to be used on a regular basis. Use it only when you have migraine symptoms, and if the tablets do not relieve your migraine then do not take any more for that migraine.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much of this medicine.
