How Botulinum Toxin Type A Works and Treatment Tips

When and How to Use It

General considerations for when and how to take botulinum toxin type A include the following:
  • The drug comes in injectable form. It is injected directly into the muscles that are causing the problems. When treating severe sweating, botulinum toxin type A is injected directly into the underarm.
  • When treating misaligned eyes (strabismus), special techniques, sometimes using the electrical signals from the muscles, must be used to make sure that the injections are given in the right place.
  • Your healthcare provider may choose to use an anesthetic cream to numb your skin before the injection, but this is not necessary. If you are worried about pain, be sure to ask your healthcare provider about using an anesthetic cream.
  • The effects of botulinum toxin type A are not permanent. You will need to receive injections periodically in order to maintain the effects.
  • For the medication to work properly, it must be taken as prescribed.

How Does Botulinum Toxin Type A Work?

Botulinum toxin type A is a toxin produced by Clostridium botulinum bacteria. The drug works by decreasing nerve signals to muscles, which helps them to relax. Botulinum toxin type A enters nerve cells and inhibits the release of acetylcholine, a chemical that transmits signals from nerve to nerve. The actions of botulinum toxin type A are not permanent, and the muscle will eventually recover and return to its previous state.
For severe sweating, botulinum toxin type A works similarly, blocking the release of acetylcholine from the nerve cells that stimulate the sweat glands.
