Xeomin (incobotulinumtoxinA, also called botulinum toxin type A), is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity.
Xeomin is used to treat cervical dystonia (severe spasms in the neck muscles). It is also used to treat muscle spasms (stiffness) in the arms.
Xeomin 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.
