What is Nimbex?

Nimbex is used to relax the muscles. It works by blocking the signals between your nerves and your muscles.

Nimbex is given before general anesthesia in preparing you for surgery. This medicine helps keep your body still during surgery. It also relaxes your throat so a breathing tube can be more easily inserted before the surgery.

Nimbex may also be used for purposes not listed in this medication guide.
