Boxed Warning

WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF PERCOCET

Addiction, Abuse, and Misuse
Because the use of PERCOCET exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient’s risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions  .

Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with use of PERCOCET, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of PERCOCET are essential [ see WARNINGS] .  

Accidental Ingestion
Accidental ingestion of even one dose of PERCOCET, especially by children, can result in a fatal overdose of Oxycodone .

Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants
Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of PERCOCET and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate .

Neonatal Opioid Withdrawal Syndrome (NOWS)
Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery .

Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)

Healthcare providers are strongly encouraged to complete a REMS-compliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription .

Cytochrome P450 3A4 Interaction
The concomitant use of PERCOCET with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in oxycodone plasma concentration. Monitor patients receiving PERCOCET and any CYP3A4 inhibitor or inducer .

Hepatotoxicity
Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 mg per day, and often involve more than one acetaminophen-containing product.

Poison Help

If you suspect an overdose or accidental ingestion, call Poison Control: 1-800-222-1222 (free, 24/7, U.S.). For life-threatening symptoms, call 911.

Medication Guide
 PERCOCET® (

ˈpər-kō-ˌset)


(oxycodone and acetaminophen)
Tablets, CII

PERCOCET is:

  • A strong prescription pain medicine that contains an opioid (narcotic) that is used to manage pain, severe enough to require an opioid analgesic and for which alternative treatments are inadequate and when other pain treatments such as non-opioid pain medicines do not treat your pain well enough or you cannot tolerate them.
  • An opioid pain medicine that can put you at risk for overdose and death. Even if you take your dose correctly as prescribed you are at risk for opioid addiction, abuse, and misuse that can lead to death.

Important information about PERCOCET tablets:

  • Get emergency help or call 911 right away if you take too much PERCOCET (overdose). When you first start taking PERCOCET, when your dose is changed, or if you take too much (overdose), serious or life-threatening breathing problems that can lead to death may occur. Ask your healthcare provider about medicines like naloxone or nalmefene that can be used in an emergency to reverse an opioid overdose.

  • Taking PERCOCET with other opioid medicines, benzodiazepines, gabapentinoids (gabapentin or pregabalin), alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.

  • Never give anyone else your PERCOCET. They could die from taking it. Selling or giving away PERCOCET is against the law.

  • Store PERCOCET securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.

Do not take PERCOCET if you have:

  • Severe asthma, trouble breathing, or other lung problems.
  • A bowel blockage or have narrowing of the stomach or intestines.
  • Known hypersensitivity to oxycodone, acetaminophen, or any ingredient in PERCOCET

Before taking PERCOCET , tell your healthcare provider if you have a history of:

  • Head injury, seizures
  • Liver, kidney, thyroid problems
  • Problems urinating
  • Pancreas or gallbladder problems
  • Abuse of street or prescription drugs, alcohol addiction, opioid overdose, or mental health problems

Tell your healthcare provider if you are:

  • Noticing your pain getting worse. If your pain gets worse after you take PERCOCET, do not take more of PERCOCET without first talking to your healthcare provider. Talk to your healthcare provider if the pain that you have increases, if you feel more sensitive to pain, or if you have new pain after taking PERCOCET.
  • Pregnant or planning to become pregnant. Use of PERCOCET for an extended period of time during pregnancy can cause withdrawal symptoms in your newborn baby that could be life-threatening if not recognized and treated.
  • Breastfeeding. PERCOCET passes into breast milk and may harm your baby. Carefully observe infants for increased sleepiness (more than usual), breathing difficulties, or limpness. Seek immediate medical care if you notice these signs.
  • Living in a household where there are small children or someone who has abused street or prescription drugs.
  • Taking prescription or over-the-counter medicines, vitamins, or herbal supplements. Taking PERCOCET with certain other medicines can cause serious side effects that could lead to death.

When taking PERCOCET:

  • Do not change your dose. Take PERCOCET exactly as prescribed by your healthcare provider. Use the lowest dose possible for the shortest time needed.
  • For acute (short-term) pain, you may only need to take PERCOCET for a few days. You may have some PERCOCET left over that you did not use. See disposal information at the bottom of this section for directions on how to safely throw away (dispose of) your unused PERCOCET.
  • Take your prescribed dose every 6 hours at the same time every day as needed for pain. Do not take more than your prescribed dose. If you miss a dose, take your next dose at your usual time.
  • Call your healthcare provider if the dose you are taking does not control your pain.
  • If you have been taking PERCOCET regularly, do not stop taking PERCOCET without talking to your healthcare provider.
  • Dispose of expired, unwanted, or unused PERCOCET by promptly flushing down the toilet, if a drug take-back option is not readily available. Visit www.fda.gov/drugdisposal for additional information on disposal of unused medicines.

While taking PERCOCET DO NOT:

  • Drive or operate heavy machinery, until you know how PERCOCET affects you. PERCOCET can make you sleepy, dizzy, or lightheaded.
  • Drink alcohol or use prescription or over-the-counter medicines that contain alcohol. Using products containing alcohol during treatment with PERCOCET  may cause you to overdose and die.
The possible side effects of PERCOCET:
  • Constipation, nausea, sleepiness, vomiting, tiredness, headache, dizziness, abdominal pain. Call your healthcare provider if you have any of these symptoms and they are severe.

Get emergency medical help or call 911 right away if you have:

  • Trouble breathing, shortness of breath, fast heartbeat, chest pain, swelling of your face, tongue, or throat, extreme drowsiness, light-headedness when changing positions, feeling faint, agitation, high body temperature, trouble walking, stiff muscles, or mental changes such as confusion.

These are not all the possible side effects of PERCOCET. Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. For more information go to dailymed.nlm.nih.gov, www.endo.com or call 1-800-828-9393.
