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 injection is used to treat cervical dystonia (severe spasms in the neck muscles), or muscle stiffness in the elbows, wrists, fingers, ankles, or toes.

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.

Xeomin is also used to treat chronic drooling (sialorrhea).

Xeomin is also used to temporarily lessen the appearance of facial wrinkles (sometimes called "frown lines") between the eyebrows.
