Fentanyl Patch

What It's For & How To Take

Fentanyl is used to treat moderate to severe ongoing pain. This medication is an opiate, and it works in the brain to block how the body recognizes pain.

Fentanyl patch is normally used on a regular schedule rather than as needed. Usually, the patch is changed every 72 hours. When you apply your patch, select a dry, non-hairy and flat part of your body. Do not apply the patch on a burn, scratch or other irritated parts of your skin. You may clean the skin with water; however, do not use soap because the patch may not stick as well. After you apply the patch, hold it down for 30 seconds to make sure it sticks.

When you apply your first patch of fentanyl, it may take between 8-24 hours before you feel the full effect of the medication. Talk with your doctor or pharmacist about how you should manage your pain during this time.

Remove the old patch before applying the new patch. Place the new patch on a different location to decrease skin irritation. When you remove the old patch, fold it together and put it in a container before placing it in the garbage. This will help prevent a child or animal from accidentally getting it.

Wash your hands well after handling the patch. If the patch is not sticking well, use some tape to hold down the edges or call your pharmacist to ask them how to keep the patch on. If the patch comes off before the next patch is due, apply another patch to a different location. Let your doctor or pharmacist know if your patches are not staying on.

Your doctor may prescribe a short-acting pain medication to be taken with your fentanyl patch. This medication will be used for sudden or sharp pain that flares up during certain times of the day.

Tell your doctor if your pain is not getting better. Your dose is based on your current condition and may need to be changed as your condition changes. Do not stop taking this medication suddenly because you may feel uncomfortable withdrawal symptoms such as muscle aches, sweating, nausea, and vomiting. Your doctor may decrease your dose over a time to decrease withdrawal symptoms.
