Uses of This Medicine:

Desflurane belongs to the group of medicines known as general anesthetics. Inhaled desflurane is used to cause general anesthesia (loss of consciousness) before and during surgery in adults.

This medicine is to be given only by or under the direct supervision of a trained doctor.

Before Using This Medicine:

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Children—

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of inhaled desflurane in children after receiving other anesthetics.

General anesthetics may cause some people to feel drowsy, tired, or weak. They may also cause problems with coordination and one's ability to think.
