What is Imigran FDT used for?

Imigran FDT contains the active ingredient sumatriptan succinate. This medicine belongs to a group of drugs called serotonin agonists.

Imigran FDT is used to relieve a migraine attack. It should not be used to prevent migraine attacks from occurring. Imigran FDT may be used for migraine headaches with or without what is known as ‘aura’.

It is thought that migraine headache is due to widening of certain blood vessels in the head. Imigran FDT works by making those vessels normal again and eases the symptoms of migraine.

Your Imigran FDT does not work in other types of headache which are not a migraine.

Imigran FDT is not addictive.

How do I take Imigran FDT?

Take your medicine as your doctor has told you. The label on the pack will tell you how many tablets to take and how often you should take them. If you do not understand what you should do, ask your doctor or pharmacist.

How much to take

The recommended starting dose for adults aged 18 to 65 is 50 mg, however you may need to have your dose of Imigran FDT increased to 100 mg. Your doctor will tell you which dose is right for you.

If the first Imigran FDT helps your migraine, but the migraine comes back later, you may take another Imigran FDT. Do not take more than 300 mg of Imigran FDT in any twenty-four hour period. Six pink (50 mg strength) or three white (100 mg strength) FDT contain 300 mg.

Do not take more Imigran FDT, or any other form of Imigran, if the first dose 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 is not relieved by Imigran, you may use Imigran FDT on another occasion to treat another migraine attack. Provided there are no side effects, you can use Imigran FDT to treat at least three separate migraine attacks before you and your doctor decide this medicine is ineffective for you.

How to take it

Imigran FDT should be swallowed with a drink of water. Do not crush or chew the tablet as it has a bitter taste.

When to take it

It is best to take your Imigran FDT

  1. when the migraine headache begins; or
  2. when other symptoms of the migraine begin, such as nausea (feeling sick), vomiting or your eyes becoming sensitive to light.

If you take your tablet later during the migraine attack it will still work for you. Do not take your Imigran FDT before the above symptoms occur.

What do I do if I take too much? (Overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 131126) for advice, if you think you or anyone else may have taken too many Imigran FDTs, 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.
