Fentanyl patches are used to relieve strong pain.
Use fentanyl patches regularly as directed. Apply the patch to a clean, dry, hairless area of skin every 3 days. When you have removed the old patch, apply the new one in a different place to prevent irritating your skin. Do not cut the patch.
If you forget to change the patch, remove the old patch and apply a new one as soon as possible.
Some medicines available without a prescription may react with fentanyl including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. valerian) or recreational drugs.
