Summary

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 smoothing of facial wrinkles and improving your appearance

Severe underarm sweating

Cervical dystonia - a neurological disorder that causes severe neck and shoulder muscle contractions

Blepharospasm - uncontrollable blinking

Strabismus - misaligned eyes

Chronic migraine

Overactive bladder

Botox injections work by weakening or paralyzing certain muscles or by blocking certain nerves. The effects last about three to twelve months, depending on what you are treating. The most common side effects are pain, swelling, or bruising at the injection site. You could also have 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 breastfeeding.
