Botox is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity.
Botox is used to treat cervical dystonia (severe spasms in the neck muscles), or severe underarm sweating (hyperhidrosis).
Botox is also used to treat certain eye muscle conditions caused by nerve disorders. This includes uncontrolled blinking or spasm of the eyelids, and a condition in which the eyes do not point in the same direction.
Botox is also used to temporarily lessen the appearance of facial wrinkles.
Botox may also be used for purposes other than those listed here.
