Oxycodone & Acetaminophen

After Your Visit

Common brands: Percocet®

​​​What it's used for​

Oxycodone with acetaminophen is used to treat pain. Oxycodone is an opioid (narcotic), which means that it works like morphine.​

​​​What to tell the doctor or phar​macist before you take this medicine

Tell the doctor or pharmacist if you:

  • have kidney or liver disease
  • drink alcohol
  • take a blood “thinner”
  • are pregnant
  • are allergic to narcotics (e.g., codeine, morphine) or acetaminophen
  • have breathing problems (asthma, COPD)

Tell your doctor or dentist what other prescription, over-the-counter, or herbal medicine you take.

​​​What you need to know

  • Take this product as directed. Taking more than 4000 mg of acetaminophen a day can hurt the liver.
  • Acetaminophen is found in pain, fever, cough, and cold medic​ine. Make sure you ask your pharmacist or read the label before you take any other medicine.
  • It works best if you take it when the pain starts or before it gets too bad.
  • Drinking alcohol while taking this medicine can hurt the liver.
  • Oxycodone frequently causes constipation. Talk to your pharmacist about whether a laxative might be right for you. Eating more fibre and drinking more fluids can help prevent it.
  • Don’t take more than prescribed or longer than prescribed: This medicine can cause withdrawal symptoms (e.g., feeling restless, sweating) if used for a long time or in high doses.
  • Don’t drive or use machinery until you know how the medicine affects you.

​​​Possible side effects

Possible side effects can include:

  • constipation
  • stomach pain
  • upset stomach /throwing up
  • feeling sleepy
  • feeling dizzy or light headed
