USARx offers the following ways to purchase this medication. Choose the Best option for you!
Endocet contains a combination of acetaminophen and oxycodone. Oxycodone is an opioid pain medication. An opioid is sometimes called a narcotic. Acetaminophen is a less potent pain reliever that increases the effects of oxycodone.
Endocet is used to relieve moderate to severe pain.
Endocet may also be used for purposes not listed in this medication guide.
You should not use Endocet if you have recently used alcohol, sedatives, tranquilizers, or other narcotic medications.
Endocet can slow or stop your breathing, and may be habit-forming. Use only your prescribed dose, and swallow the pill whole to avoid a potentially fatal dose. Never share Endocet with another person.
MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have nausea, pain in your upper stomach, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of your skin or eyes).
Oxycodone may cause life-threatening withdrawal symptoms in a newborn if the mother has taken Endocet during pregnancy.
An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have nausea, pain in your upper stomach, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of your skin or eyes).
Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
You should not use Endocet if you are allergic to acetaminophen (Tylenol) or oxycodone, or if:
you have severe asthma or breathing problems;
you have a blockage in your stomach or intestines, including paralytic ileus; or
you have recently used alcohol, sedatives, tranquilizers, or other narcotic medications.
Some medicines can interact with oxycodone and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
To make sure Endocet is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
liver disease, cirrhosis, or if you drink alcohol daily;
a history of drug abuse, alcohol addiction, or mental illness;
kidney disease, urination problems;
problems with your gallbladder, pancreas, thyroid, or adrenal gland;
a history of head injury, brain tumor, or seizures; or
if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others).
Endocet is more likely to cause breathing problems in older adults and people who are severely ill, malnourished, or otherwise debilitated.
If you use oxycodone 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 habit-forming medicine may need medical treatment for several weeks. You should not breast-feed while using this medicine.
Acetaminophen and oxycodone may pass into breast milk and could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Take Endocet exactly as prescribed. Follow all directions on your prescription label. Oxycodone can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never use Endocet 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.
Oxycodone may be habit-forming, even at regular doses. Never share Endocet with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away Endocet is against the law.
If you need surgery, tell the surgeon ahead of time that you are using Endocet. You may need to stop using the medicine for a short time.
Do not stop using this medicine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using the medicine.
Store Endocet at room temperature away from moisture and heat. Keep track of the amount of medicine used from each new bottle. Oxycodone is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover Endocet tablets. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush any unused tablets down the toilet.
Never crush or break an Endocet tablet to inhale the powder or mix it into a liquid to inject the drug into your vein.
Since Endocet is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose can be fatal, especially in a child or other person using this medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, and fainting.
The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness.
Do not drink alcohol. Dangerous side effects or death could occur.
Endocet may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose.
Get emergency medical help if you have signs of an allergic reaction to Endocet: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction. Stop taking Endocet and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Like other narcotic medicines, oxycodone can slow your breathing. Death may occur if breathing becomes too weak.
Call your doctor at once if you have:
shallow breathing, slow heartbeat;
a light-headed feeling, like you might pass out;
confusion, unusual thoughts or behavior;
seizure (convulsions);
problems with urination;
infertility, missed menstrual periods;
impotence, sexual problems, loss of interest in sex;
liver problems - nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes); or
low cortisol levels - nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.
Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Common Endocet side effects include:
headache, drowsiness, tiredness;
nausea, vomiting, stomach pain, constipation;
blurred vision; or
dry mouth.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Narcotic (opioid) medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:
other narcotic medications - opioid pain medicine or prescription cough medicine;
drugs that make you sleepy or slow your breathing - a sleeping pill, muscle relaxer, sedative, tranquilizer, or antipsychotic medicine; or
drugs that affect serotonin levels in your body - medicine for depression, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting.
This list is not complete. Other drugs may interact with acetaminophen and oxycodone, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.

For the ConsumerApplies to acetaminophen / oxycodone: oral solution, oral tablet
Oral route (Tablet; Tablet, Extended Release)
Addiction, Abuse, and MisuseOxycodone/acetaminophen 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 oxycodone/acetaminophen, and monitor all patients regularly for the development of these behaviors or conditions.Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse and misuse, the Food and Drug Administration (FDA) has required a REMS for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to: complete a REMS-compliant education program, counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products, emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacists, and consider other tools to improve patient, household, and community safety.Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of oxycodone/acetaminophen. Monitor for respiratory depression, especially during initiation of oxycodone/acetaminophen or following a dose increase.Instruct patients to swallow oxycodone/acetaminophen ER tablets whole; crushing, chewing, or dissolving oxycodone/acetaminophen ER can cause rapid release and absorption of a potentially fatal dose of oxycodone Accidental IngestionAccidental ingestion of even one dose of oxycodone/acetaminophen, especially by children, can result in a fatal overdose of oxycodone.Neonatal Opioid Withdrawal SyndromeProlonged use of oxycodone/acetaminophen during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.Cytochrome P450 3A4 InteractionThe concomitant use of Oxycodone/acetaminophen 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 Oxycodone/acetaminophen and any CYP3A4 inhibitor or inducer.HepatotoxicityAcetaminophen 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 milligrams per day, and often involve more than one acetaminophen-containing product Risks from Concomitant Use with Benzodiazepines or Other CNS DepressantsReserve concomitant prescribing of oxycodone/acetaminophen and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.
