Description

Fentanyl (FEN-ta-nil) belongs to the group of medicines called narcotic analgesics (nar-KOT-ik an-al-GEE-ziks) . Narcotic analgesics are used to relieve pain. The transdermal system (skin patch) form of fentanyl is used to treat chronic pain (pain that continues for a long time).

Fentanyl acts in the central nervous system (CNS) to relieve pain. Some of its side effects are also caused by actions in the CNS.

When a narcotic is used for a long time, it may become habit-forming (causing mental or physical dependence). However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain . Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by reducing the dose gradually over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription. Prescriptions for transdermal fentanyl cannot be refilled. You will need to obtain a new prescription from your doctor each time you need the medicine. This medicine is available in the following dosage form:
