Duragesic Side Effects
What should I watch for?
Tell your doctor or health care professional if your pain does not go away, if it gets worse, or if you have new or a different type of pain. You may develop tolerance to the medicine. Tolerance means that you will need a higher dose of the medicine for pain relief. Tolerance is normal and is expected if you take the medicine for a long time.
Do not suddenly stop taking your medicine because you may develop a severe reaction. Your body becomes used to the medicine. This does NOT mean you are addicted. Addiction is a behavior related to getting and using a drug for a non-medical reason. If you have pain, you have a medical reason to take pain medicine. Your doctor will tell you how much medicine to take. If your doctor wants you to stop the medicine, the dose will be slowly lowered over time to avoid any side effects.
There are different types of narcotic medicines (opiates). If you take more than one type at the same time or you are taking another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.
This medicine patch is sensitive to certain body heat changes. If your skin gets too hot, more medicine will come out of the patch and can cause a deadly overdose. Call your healthcare provider if you get a fever. Do not take hot baths. Do not sunbathe. Do not use hot tubs, saunas, hair dryers, heating pads, electric blankets, heated waterbeds, or tanning lamps. Do not do exercise that increases your body temperature.
If you are going to need surgery, a MRI, CT scan, or other procedure, tell your doctor that you are using this medicine. You may need to remove this patch before the procedure.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that may be dangerous until you know how the medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.
The medicine will cause constipation. Try to have a bowel movement at least every 2 to 3 days. If you do not have a bowel movement for 3 days, call your doctor or health care professional.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
