Fentanyl



Pronunciation: FEN-ta-nil
Generic Name: Fentanyl
Brand Name: Sublimaze


Fentanyl is used for:

Producing anesthesia for surgery and treating pain before, during, and after surgery. It may also be used with other medicines.


Fentanyl is a narcotic (opioid) analgesic. It works in the brain and nervous system to cause anesthesia and decrease pain.


Do NOT use Fentanyl if:


  • you are allergic to any ingredient in Fentanyl or any related medicine (eg, sufentanil)

  • you take sibutramine or sodium oxybate (GHB)

Contact your doctor or health care provider right away if any of these apply to you.
