What is acetaminophen and oxycodone?
Oxycodone is an opioid pain medication, sometimes called a narcotic.
Acetaminophen is a less potent pain reliever that increases the effects of oxycodone.
Acetaminophen and oxycodone is a combination medicine used to relieve moderate to severe pain.
Acetaminophen and oxycodone may also be used for purposes not listed in this medication guide.
Stop taking acetaminophen and oxycodone and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.
An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have pain in your upper stomach, loss of appetite, dark urine, or jaundice (yellowing of your skin or eyes).
Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Oxycodone may be habit-forming and should be used only by the person it was prescribed for. Keep the medication in a secure place where others cannot get to it. Acetaminophen and oxycodone can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use this medicine if you are allergic to acetaminophen or oxycodone, or if you have:
severe asthma or breathing problems; or
a blockage in your stomach or intestines.
To make sure acetaminophen and oxycodone is safe for you, tell your doctor if you have ever had:
a drug or alcohol addiction;
urination problems; or
problems with your thyroid, pancreas, or gallbladder.
If you use opioid medicine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on opioids may need medical treatment for several weeks.
Do not breast-feed. Acetaminophen and oxycodone can pass into breast milk and cause drowsiness, breathing problems, or death in a nursing baby.
How should I take acetaminophen and oxycodone?
Take acetaminophen and oxycodone exactly as it was prescribed for you. Follow all directions on your prescription label. Never take acetaminophen and oxycodone in larger amounts, or for longer than prescribed. An overdose can damage your liver or cause death. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Never share acetaminophen and oxycodone with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medicine in a place where others cannot get to it. Selling or giving away acetaminophen and oxycodone is against the law.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
If you need surgery or medical tests, tell the doctor ahead of time that you are using this medicine.
You should not stop using acetaminophen and oxycodone suddenly. Follow your doctor's instructions about tapering your dose.
Store at room temperature away from moisture and heat. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
