What is Imigran Mk II injection used for?
Imigran Mk II injection contains the active ingredient sumatriptan succinate. This medicine belongs to a group of drugs called serotonin agonists.
Imigran Mk II injection is used to relieve a migraine attack or cluster headache. It should not be used to prevent migraine attacks or cluster headaches from occurring. Imigran Mk II injection may be used for migraine headaches with or without what is known as 'aura'.
It is thought that migraine headaches and cluster headaches are due to widening of certain blood vessels in the head. Imigran Mk II injection works by making those vessels normal again and eases the symptoms of migraine and cluster headaches.
Your Imigran Mk II injection does not work in other types of headache which are not a migraine or a cluster headache.
Imigran Mk II injection is not addictive.

How do I use Imigran Mk II injection?
The first time you ever have an Imigran Mk II injection it must be under the supervision of a doctor. After this you must use the injection as your doctor has instructed.
See the patient instruction leaflet inside the pack for information on how to load the Autoinjector with the syringe and how to discard the empty syringes. If there is something you do not understand, ask your doctor or pharmacist.
How much to use
For adults aged 18 to 65, the dose is one injection of 6 mg, just under the skin, on the outside of the thigh.
If the first Imigran Mk II injection helps your migraine or cluster headache, but the headache/migraine comes back later, you may use another Imigran Mk II injection. You must wait at least one hour between using the first and second Imigran Mk II injection. Do not use more than 2 injections (2 x 6 mg) in any twenty-four hours.
Do not use a second injection, or any other form of Imigran, if the first injection has not provided any relief from your symptoms. You may take your usual headache relief medication provided it does not contain ergotamine or methysergide. If you are not sure what to do, ask your doctor or pharmacist.
If your migraine or cluster headache is not relieved by Imigran, you may use Imigran Mk II injection on another occasion to treat another attack. Provided there are no side effects, you can use Imigran Mk II injection to treat at least three separate migraine or cluster headache attacks before you and your doctor decide this medicine is ineffective for you.
How to use it
Imigran Mk II injection should be injected just under the skin on the outside of the thigh using the autoinjector (see the patient instruction leaflet inside the pack).
When to use it
It is best to use your Imigran Mk II injection -
- when the migraine headache or cluster 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 use Imigran Mk II injection later during the attack it will still work for you. Do not use your Imigran Mk II injection before the above symptoms occur.
What do I do if I use too much? (Overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 131126) for advice, if you think you or anyone else may have used too many Imigran Mk II injections, even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you are not sure what to do, contact your doctor or pharmacist.
