Fentanyl Patches
What is a fentanyl patch?
A fentanyl patch is a thin, ‘plastic’ patch, similar to a Nicoderm® patch in appearance. It is applied to your pet’s skin and delivers a morphine-like medication called fentanyl through the skin and into the bloodstream to help alleviate pain.
What if my pet is taking other medications?
It is important to let your doctor know if your pet is receiving any other medications since they may interfere with the fentanyl. Some medications can negate the effects of the fentanyl; others may intensify the effects. Please provide your doctor with a list of all medications (prescribed or over the counter) that you are currently giving your pet.

How can I expect my pet to respond to the fentanyl patch?
The normal reaction to a fentanyl patch is relaxation, however some pets will seem anxious or agitated. This is particularly true of the first night after your pet returns home, as the excitement of returning home is exacerbated by the dysphoria of the narcotic, fentanyl. This will resolve within a day of being home.
Infrequently, pets may be ‘sensitive’ to the fentanyl. If your pet seems unresponsive or has any difficulty breathing, please call your doctor.
What should I avoid when my pet has a fentanyl patch?
Do not allow your pet to lick or chew the fentanyl patch. If necessary an Elizabethan collar may need to be applied to prevent this from happening.
Heat may increase the amount of medication that is absorbed through the skin of your pet from the patch. Do not use hot water bottles, electric blankets, heating pads or other sources of direct heat on the patch.

What should I do if the patch falls off?
If the patch falls off, discard it by folding it in half so that the adhesive surface sticks to itself and flush it down the toilet immediately. Avoid contact with the adhesive surface of the patch as it may contain medication that could be absorbed through your skin.
When and how should I remove the patch?
The patch can be removed 3 to 5 days after it is applied. To remove: hold the skin in front of the patch steady and pull the patch off sharply in the direction of hair growth. The patch can be very adherent. If you are uncomfortable removing the patch, please return to the hospital and one of our technicians can do this for you.
Important: Keep the fentanyl patch out of the reach of children!
