    • Services and providers for Botox in the U.S.

Also called: Botulinum toxin type A

Botox is a drug made from a toxin produced by the bacterium Clostridium botulinum. It's the same toxin that causes a life-threatening type of food poisoning called botulism. Doctors use it in small doses to treat health problems, including

  • Temporary removal of facial wrinkles
  • Severe underarm sweating
  • Cervical dystonia - a neurological disorder that causes severe neck and shoulder muscle contractions
  • Blepharospasm - uncontrollable blinking
  • Strabismus - misaligned eyes

Botox injections work by weakening or paralyzing certain muscles or by blocking certain nerves. The effects last about three to four months. Side effects can include pain at the injection site, flu-like symptoms, headache and upset stomach. Injections in the face may also cause temporary drooping eyelids. You should not use Botox if you are pregnant or breast feeding.
