How to use Duragesic Patch:

Use Duragesic Patch as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Duragesic Patch comes with an additional patient information sheet called a Medication Guide. Read it carefully and reread it each time you get Duragesic Patch refilled.
• Apply Duragesic Patch immediately after removing it from the individually sealed package. Do not alter (eg, cut) the patch in any way before applying it.
• The patch should be applied to a dry, smooth, non-irradiated section of skin on your chest or back. In young children or patients with mental impairment, place patch on their upper back to decrease the chance that they will remove the patch and put it in their mouth.
• Before applying the patch, clip (do not shave) any hair at the application site, clean the area with clear water only, and then dry the area. Do not use soaps, oils, lotions, or any other liquid that could irritate or otherwise affect the skin.
• Press the patch firmly in place with the palm of your hand for 30 seconds. Make sure the contact is complete, especially around the edges. Wash your hands after applying the patch.
• A patch may be worn continuously for 72 hours. If pain relief for more than 72 hours is needed, apply a new patch to a different skin area after removing the old patch.
• After removing the used patch, fold over with the sticky side together. The patch should be flushed down the toilet immediately upon removal. You should also dispose of any unused patches remaining from a prescription as soon as they are no longer needed. Unused patches should be removed from their pouches and flushed down the toilet.
• If you forget to change your patch on the day it is due, change the patch as soon as you remember. Do not use 2 patches at the same time.

Ask your health care provider any questions you may have about how to use Duragesic Patch.

Important safety information:

• Do not expose the patch on your skin to direct sources of heat, such as fevers, heating pads, electric blankets, heat lamps, saunas, hot tubs, or heated waterbeds. Avoid sunbathing, long hot baths, or other sources of heat to the body. The heat may cause more medicine to be released into your skin.
• The patch contains a strong narcotic pain medicine (similar to morphine, hydromorphone, methadone, oxycodone, and oxymorphone) in the form of a gel. If the gel should leak from the patch at any time, do not touch the gel. If you have unintended contact with the gel, immediately wash the affected area with large amounts of water only. If you have concerns, speak with your pharmacist or doctor for further instructions.
• If the patch comes off your skin and accidentally sticks to the skin of another person, remove the patch from their skin immediately, wash the exposed area of skin with water and call you doctor, emergency room, or local poison control center immediately.
• Before you have any medical or dental treatments, emergency care, or surgery, tell the doctor or dentist that you are using Duragesic Patch.
