botulinum toxin is a protein produced by a certain type of bacteria (clostridium botulinum). it is the same toxin that can cause a type of foodborne illness (botulism) if a person gets too much in his or her system. it may be used to treat a wide range of problems.
botox shots may be used to treat a wide range of problems, such as:
- removing wrinkles on the face.
- preventing underarm sweating in people who sweat too much.
- relaxing muscles that cause spasms in the eyelids or the esophagus.
- treating chronic migraine headaches.
- reducing urinary incontinence.
the effect usually wears off within a few months. when botox is injected in small amounts into muscles, it doesn't get into a person's blood or cause sickness.
