Injection

Botulinum toxin type A is a protein substance which is produced by the bacterium Clostridium botulinum. It is a neurotoxin which means that it interferes with the way nerves work. To be eligible for this treatment you must have headaches for 15 or more days each month, with migraine headaches being on at least eight of these days. You must also have tried several other medicines to prevent migraine before this treatment is prescribed for you.

Botulinum toxin type A is thought to work in chronic migraine by relaxing muscles and by blocking the pain signals which are involved in the development of a migraine. These actions may have the effect of stopping a migraine headache from being triggered.

Botulinum toxin injections are also used for other reasons (including cosmetic purposes, muscle spasms, bladder problems, and excessive sweating). This leaflet does not cover the use of botulinum toxin type A in these ways.

Before being treated with botulinum toxin type A

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before being treated with botulinum toxin type A for migraine, make sure that your doctor knows:

  • Om du är gravid, försöker bli gravid eller ammar.

  • If you have an infection or any swelling near any of the areas that will be injected.

  • If you have any muscle problems, particularly any muscle weakness.

  • If you have ever had any difficulty in swallowing or with your breathing.

  • Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

  • Om du någonsin har haft en allergisk reaktion mot en medicin.

How you will be given botulinum toxin type A

  • Before you start the treatment, ask to read the manufacturer's printed information leaflet from inside the pack. It will give you more information about Botox® and will provide you with a full list of the side-effects which you may experience from having it.

  • You will be given botulinum toxin type A by a doctor who is trained in the use of this treatment. It will be injected into the muscles around your head and neck in several different places.

  • If the treatment proves successful for you, your doctor is likely to recommend that it is repeated every 12 weeks.
