Duragesic is a skin patch containing fentanyl, an opioid pain medication. An opioid is sometimes called a narcotic.

Duragesic patches are a strong prescription pain medicine. The patches are used to treat moderate to severe chronic pain in opioid-tolerant patients, severe enough to require daily, around-the-clock, long-term opioid treatment.

Duragesic patches are used when other pain treatments such as non-opioid pain medicines or immediate-release opioid medicines do not treat your pain well enough or you cannot tolerate them.

Duragesic patches are not for treating mild or occasional pain or pain from surgery. The patches are not for use to treat pain that is not around-the-clock.

• Other Brand Names: Amphadase, Hylenex, Vitrase, Wydase, Hydase

Hyaluronidase injection is a spreading substance. It is used with other medicines given under the skin to improve their uptake by the body. This method of drug delivery is only used when the drug cannot be given by injection into a vein. Hyaluronidase injection is also used to increase absorption of fluids or medicines that are injected into your skin. It also used to help improve absorption of radioactive substances during a procedure called subcutaneous urography.

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