What is Imigran nasal spray used for?

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

Imigran nasal spray is used to relieve a migraine attack. It should not be used to prevent migraine attacks from occurring. Imigran nasal spray 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 nasal spray works by making those vessels normal again and eases the symptoms of migraine.

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

Imigran nasal spray is not addictive.

How do I use Imigran nasal spray?

See the patient instruction leaflet inside the pack for information on how to use your Imigran nasal spray. If there is something you do not understand, ask your doctor or pharmacist.

How much to use

Adults and Adolescents (12 years and over): The dose is one nasal spray of 10 mg or 20 mg. Your doctor will tell you which dose is right for you.

If the first Imigran nasal spray helps your migraine, but the migraine comes back later, you may use another Imigran nasal spray. You must wait at least two hours between using the first and second Imigran nasal spray. Do not use more than 40 mg of Imigran nasal spray in any twenty-four hours. Four 10 mg strength or two 20 mg strength nasal sprays contain 40 mg.

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

When to use it

It is best to use your Imigran nasal spray:

  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 use your Imigran nasal spray later during the migraine attack it will still work for you. Do not use your Imigran nasal spray before the above symptoms occur.

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

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, if you think you or anyone else may have used too many Imigran nasal sprays, 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.

If you accidentally spray Imigran in your eye(s) wash them with plenty of water. If there is any irritation seek medical help.
