What is Zemuron?

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

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

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

Tell your doctor if you have ever had a severe allergic reaction to any type of anesthesia.
