Highlights for acetaminophen-oxycodone

Oral tablet

Oxycodone/acetaminophen is an oral medication used to treat moderate to severe pain.


This medication may cause severe or life threatening reactions in people with asthma or other lung problems, an allergy to the drug, or a bowel blockage.


Don’t take more medication than prescribed. In general, the maximum safe dosage of acetaminophen, including acetaminophen in all medications you take, is 4,000 mg per day.


This medication may be addicting or habit forming, even at regular doses. Never share it, especially with someone with a history of drug misuse.


This medication can have negative effects in people with certain health conditions. Tell your doctor if you have seizures, head injuries, and problems urinating.


FDA warning

This drug has a Black Box Warning. This is the most serious warning from the Food and Drug Administration (FDA). A black box warning alerts doctors and patients to potentially dangerous effects.

Addiction, abuse, and misuse: This medication has a risk of addiction, abuse, and misuse, which can lead to overdose and death.

Life-threatening breathing problems: Serious, life-threatening, or fatal inability to breathe may occur when you use this drug, especially in older adults. Swallow extended-release tablets whole to avoid a potentially fatal overdose.

Accidental use: Accidentally taking this medication can cause a fatal overdose of oxycodone. This is especially true for children.

Neonatal opioid withdrawal syndrome: If you use this medication for a long time while you’re pregnant, it can cause withdrawal in your baby. Withdrawal in your baby can lead to death. Symptoms of withdrawal may include:

  • irritability
  • hyperactivity and unusual sleep pattern
  • high-pitched cry
  • tremor
  • vomiting
  • diarrhea
  • failure to gain weight

Liver problems: Acetaminophen has been associated with cases of acute liver failure. This can result in the need for a liver transplant or death. Don’t take more than the maximum daily limit of acetaminophen (4,000 mg per day).

Dangerous effects with benzodiazepine use. Using oxycodone with drugs called benzodiazepines can cause dangerous effects. These can include severe drowsiness, slowed breathing, coma, and death. If your doctor prescribes a benzodiazepine with oxycodone, they will monitor you closely. Examples of benzodiazepines include lorazepram, clonazepam, and alprazolam.

Extended-release warning

Don’t use the extended-release form if you’ve been prescribed a different form. The extended-release form contains more of the drug. Using it at the same dose as the other forms can lead to increased side effects and even death.

Blood pressure warning

Contact your doctor if you experience dizziness, feeling faint, or trouble breathing.

acetaminophen-oxycodone May Interact with Other Medications

Oral tablet

Oxycodone/acetaminophen can interact with other medications, herbs, or vitamins you might be taking. That’s why your doctor should manage all of your medications carefully. If you’re curious about how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.

Note: You can reduce your chances of drug interactions by having all of your prescriptions filled at the same pharmacy. That way, a pharmacist can check for possible drug interactions.

Alcohol Interaction

Drinking alcohol while taking this medication increases your risks of negative side effects. These include slowed breathing and increased drowsiness. It also increases your risk of liver damage.

Medications That Might Interact with This Drug

Drugs that cause drowsiness

Taking these drugs with oxycodone/acetaminophen increases your risk of drowsiness, physical and mental slowing, and trouble breathing. If you need to use both drugs together, the dose of one or both should be reduced.

These drugs include:

  • sedatives
  • hypnotics
  • tranquilizers
  • general anesthetics
  • skeletal muscles relaxants
  • other opioids

Anticoagulant, blood thinner
  • warfarin


Avoid taking oxycodone/acetaminophen with monoamine oxidase inhibitors. Monoamine oxidase inhibitors can increase your risk for anxiety, confusion, breathing problems, and coma.

Pain and opiate addiction/withdrawal drugs

Avoid taking oxycodone/acetaminophen with agonist/antagonist analgesics. They can decrease how well your pain medication works, which will cause you to feel more pain.

These drugs include:

  • pentazocine
  • nalbuphine
  • butorphanol
  • buprenorphine


Avoid taking oxycodone/acetaminophen with anticholinergics. They may make it hard for you to go to have a bowel movement, which can lead to severe problems in your stomach and intestines.

Anxiety drugs (benzodiazepines)

Taking certain anxiety drugs with oxycodone/acetaminophen puts you at serious risk of severe drowsiness, slowed breathing, coma, or death. These drugs include:

  • lorazepam
  • clonazepam
  • alprazolam

Serotonergic drugs

Taking serotonergic drugs with oxycodone/acetaminophen can cause serotonin syndrome, which can be fatal. Symptoms can include agitation, sweating, muscle twitches, and confusion. Serotonergic drugs include:

  • selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine and sertraline
  • serotonin and norepinephrine reuptake inhibitors (SNRIs) duloxetine and venlafaxine
  • tricyclic antidepressants (TCAs) such as amitriptyline and clomipramine
  • monoamine oxidase inhibitors (MAOIs) such as selegiline and phenelzine

Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs interact differently in each person, we cannot guarantee that this information includes all possible interactions. This information is not a substitute for medical advice. Always speak with your healthcare provider about possible interactions with all prescription drugs, vitamins, herbs and supplements, and over-the-counter drugs that you are taking.
Drug warnings
lung problems
People with lung problems

If you have severe asthma, trouble breathing, or other lung problems, this medication can increase your risk of breathing problems. This is because it slows your breathing even more.

stomach problems
People with stomach problems

If you have a bowel blockage or narrowing of your stomach or intestines, taking this medication can make it even harder for you to have a bowel movement. This is because it tends to cause constipation.

pregnant women
Pregnant women

Oxycodone/acetaminophen is a category C pregnancy drug. That means two things:

  1. Research in animals has shown adverse effects to the fetus when the mother takes the drug.
  2. There haven’t been enough studies done in humans to be certain how the drug might affect the fetus.

Tell your doctor if you’re pregnant or plan to become pregnant. Oxycodone/acetaminophen should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

If you use this medication for a long time while you’re pregnant, it can cause withdrawal in your baby (neonatal opioid withdrawal syndrome). Withdrawal in your baby can lead to death. Symptoms of withdrawal may include:

  • irritability
  • hyperactivity and unusual sleep pattern
  • high-pitched cry
  • tremor
  • vomiting
  • diarrhea
  • failure to gain weight
Women who are breast-feeding

You shouldn’t breastfeed your baby while taking this medication. If you do, your baby may become too sleepy and may have problems breathing.

You and your doctor should decide whether you take this medication or breastfeed.

For children

The effectiveness and safety of this medication hasn’t been established in children under the age of 18 years.


This medication can cause serious skin problems. Symptoms may include skin rash and peeling, blistered skin.

Get emergency medical help if you experience:

  • trouble breathing, shortness of breath, fast heartbeat, chest pain, swelling of your face, tongue or throat, extreme drowsiness, or feeling faint
  • rash with hives, sores in your mouth or eyes, or blistering and peeling skin

Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal.
