What are some cautions about opioids?

Cautions for opioids include the following:

Some opioids have acetaminophen (Tylenol) in them, and taking too much acetaminophen can be harmful. So check the labels on all the other medicines you take, because many other medicines also contain acetaminophen. This includes over-the-counter medicines. Do not exceed 4000 mg per day of acetaminophen from all sources. Do not take other medicines with acetaminophen in them unless your doctor has told you to. Talk to your doctor or pharmacist if you have questions about this.
Do not drive or operate machinery until you can think clearly. Opioids may affect your judgment and decision making. Talk with your doctor about when it is safe to drive.
Opioids are strong medicines. There is a risk for developing opioid use disorder. Moderate to severe opioid use disorder is sometimes called addiction. This means a person keeps using opioids even though it causes problems. The risk is greater for those who have a history of substance use. If you are worried about developing opioid use disorder, talk with your doctor.
Your body gets used to opioids if you take them for a long time. This is called physical dependence. You could have withdrawal symptoms when you stop taking them. Symptoms include nausea, sweating, chills, diarrhea, and shaking. But you can avoid these symptoms if you slowly stop taking the medicine as your doctor tells you to.

General cautions for all medicines

Allergic reactions.: All medicines can cause a reaction. This can sometimes be an emergency. Before you take any new medicine, tell the doctor or pharmacist about any past allergic reactions you've had.
Drug interactions.: Sometimes one medicine may keep another medicine from working well. Or you may get a side effect you didn't expect. Medicines may also interact with certain foods or drinks, like grapefruit juice and alcohol. Some interactions can be dangerous.

Harm during pregnancy or breastfeeding.: If you are pregnant, trying to get pregnant, or breastfeeding, ask your doctor or pharmacist if all the medicines you take are safe.

Other health problems.: Before taking a medicine, be sure your doctor or pharmacist knows about all your health problems. The medicine for one health problem may affect another health problem.

Always tell your doctor or pharmacist about all the medicines you take. This includes prescription and over-the-counter medicines and natural health products. That information will help prevent serious problems.
