Other, off label uses for this medicine

This medication may be used for breakthrough pain associated with serious and chronic conditions, such as cancer.

Lynox contains acetaminophen, used to reduce fever. More Off-Label Uses for Lynox


Lynox contains oxycodone and acetaminophen.

Take Lynox with or without food. Take Lynox with food to reduce stomach upset. If you take two tablets per dose, take one tablet at a time. Drink a full glass of water with each dose to prevent choking.

Dosage is based on your condition and response to treatment. Your doctor will probably start you on a low dose of Lynox then adjust your dosage as needed.

Physicians usually suggest you take Lynox at the first sign of pain rather than on a fixed schedule. Take Lynox before your pain worsens for best results.

Lynox may cause nausea. To reduce this effect, lie down for one to two hours, keeping your head still. Talk to your healthcare provider or pharmacist about other ways to reduce nausea associated with Lynox.

Cells injured by trauma or illness release a chemical known as prostaglandin. This chemical binds to nerve endings, which then transmit the message that something has gone wrong to the brain. The brain receives and interprets the message and then responds to those messages by perceiving pain, creating inflammation at the site of injury and increasing your body temperature.

The oxycodone in Lynox stops pain by binding to the nerve endings, sending messages of pleasure and euphoria to the brain in such a way that overrides any signals of pain. Acetaminophen works by slowing the production of prostaglandins. Acetaminophen is a less potent pain reliever than oxycodone but acetaminophen and oxycodone work better together than either medicine could alone.

Along with pain relief, opioids such as Lynox reduce anxiety and causes feelings of euphoria and relaxation. Lynox causes respiratory depression, which is slow and shallow breathing, by acting directly on respiratory centers in the brain. Lynox depresses your cough reflex by directly affecting the medulla, located in the lower portion of the brain stem.

The opioids in Lynox act on smooth muscle organs, including those in your intestines, in a way that slows down the bowel movements and causes constipation. More about How Lynox Works


Let your healthcare provider know about any allergies to Lynox, another opioid such as morphine or codeine, or any other medication. An allergic reaction is a serious and potentially life-threatening medical condition. If you think you are having an allergic reaction, seek medical assistance immediately. Symptoms of an allergic reaction include rash, hives, itching, difficulty breathing, tightness in the chest and swelling of the face, mouth, lips or tongue.

Drink six to eight full glasses of water each day you take Lynox to soften stool to make it easier to have a bowel movement. Speak with your healthcare provider or dietician about ways to increase your intake of dietary fiber, known to ease constipation. Do not use a laxative or stool softener without first discussing it with a doctor.

Acetaminophen can cause inaccurate medical laboratory results, especially tests that measure the amount of sugar in the urine. Tell your doctor or laboratory technician about your Lynox use; they may recommend rescheduling your lab appointment or make a note on your results.

Tell your surgeon or dentist about Lynox use before having an operation or procedure. She may suggest you change medications or stop taking Lynox for a short time before the procedure.

The prescribing physician may switch you to a different medication or adjust your Lynox prescription if you have had a history of, or are currently suffering from, certain medical conditions. Your medical condition may change the way Lynox works, or Lynox may worsen your condition or interfere with treatment.

Tell your physician about any significant illnesses or conditions, including:

  • Asthma
  • Constipation
  • COPD
  • Diarrhea Due To Infection
  • Difficulty Urinating
  • Enlarged Prostate
  • Head Injury
  • Intestinal or Stomach Blockage
  • Kidney Disease
  • Liver Disease
  • Mental or Mood Disorders, such as Confusion or Depression
  • Paralytic Ileus
  • Personal or Family History of Regular Use or Abuse of Drugs or Alcohol
  • Seizures
  • Sleep Apnea
  • Tumor

Lynox may cause dizziness or drowsiness and can affect your ability to think clearly. Do not drive a motor vehicle or operate other heavy machinery until you know how this medication affects you. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Older adults may be more sensitive to these effects, especially dizziness, drowsiness and urinary problems. Physicians should prescribe lower doses and monitor older patients closely, especially after the initial doses.

Do not consume alcoholic beverages while taking Lynox. Drinking alcohol while taking opioids may cause serious side effects, liver damage or even death. Read the labels of foods, beverages and medications to determine if the product contains alcohol. Ask your pharmacist for help if you are not sure if a product contains alcohol.

Notify your healthcare provider if you normally drink more than three alcoholic beverages each day. Tell the prescribing physician if you have ever had cirrhosis, sometimes called alcoholic liver disease. You may not be able to use Lynox or other drugs containing acetaminophen. Chronic alcoholics should limit acetaminophen intake to less than 2000 mg per day.

Using opioids such as Lynox poses a risk for the development of dependence or addiction, especially if you take high doses or use Lynox for more than a few weeks. The physical and psychological symptoms associated with dependence or addiction makes it difficult to stop taking Lynox. To reduce your risk for dependence or addiction do not take a high dose or use Lynox more frequently than prescribed.

Notify the prescribing physicians if your current dose of Lynox stops working to relieve your pain, as this is a sign that your body is becoming tolerant to the effects of Lynox. To avoid dangerous overdose, side effects, dependence and addiction, do not increase your dose or take Lynox more frequently without the consent of the prescribing physician. Your healthcare provider may adjust your dosing schedule or recommend a different analgesic.

Using Lynox may affect the outcome of some medical laboratory tests. Notify the ordering physician or laboratory technician about your Lynox use; they may recommend abstaining from the medicine or rescheduling your laboratory appointment.

Notify all doctors, dentists and other healthcare professionals about your Lynox use before undergoing any procedures. They may recommend you stop using Lynox for a short while or reschedule your procedure.

Do not take Lynox while you are having an asthma attack or experiencing any other breathing problems. Lynox may cause respiratory depression, a dangerous and common respiratory condition associated with opioid use. Respiratory depression is characterized by slow and shallow breathing. Respiratory depression means the individual is not breathing well enough to exchange oxygen for carbon dioxide.

Using Lynox during pregnancy may cause harm to the fetus and could cause addiction or withdrawal symptoms in a newborn. Tell the prescribing physician if you are pregnant or plan to become pregnant while taking Lynox. You and your doctor will discuss the risks and benefits of taking this medication while pregnant. Lynox may pass into breast milk and might harm a nursing baby; do not take Lynox while breastfeeding.

Do not stop taking Lynox suddenly, or reduce your dose significantly, unless a doctor directs you to do so. Discontinuing Lynox abruptly, or reducing your dose unexpectedly, will cause unpleasant withdrawal symptoms in opioid dependent individuals. Try weaning yourself from Lynox use by using smaller doses further apart. If withdrawal symptoms prevent you from discontinuing Lynox use, you may be physically dependent and require the assistance of detoxification specialists.

Lynox contains acetaminophen. Taking too much acetaminophen may result in serious, or even fatal, liver disease. Many prescription and over-the-counter products include acetaminophen, including cough and cold remedies, allergies medications, sleep aides and painkillers. Ask your pharmacist to help you understand if any of your other prescription medications contain acetaminophen. Check the labels on all over-the-counter medications for acetaminophen, sometimes called APAP. Acetaminophen also goes by the brand name Tylenol. Do not consume more than 4 grams, or 4000 milligrams, of acetaminophen in a 24-hour period. More Warnings about Using Lynox

Drug Interactions

Drug interactions are always possible but do not always occur. Give the prescribing physician and pharmacist filling your order an updated list of all your prescriptions, over-the-counter products, vitamins, supplements and herbal remedies. Do not stop, start or change the dose of any medications, including non-prescription remedies, without first discussing it with your healthcare provider.

Lynox may interact unfavorably with other painkillers, especially those medications that affect breathing or cause drowsiness. Take all prescriptions and over-the-counter preparations with care, especially cold and cough remedies, anti-seizure medication, drugs for insomnia or anxiety, muscle relaxants or certain psychiatric medications. Talk with your pharmacist about possible drug interactions when you fill your Lynox prescription.

Other medications may affect the rate at which your body processes and disposes of oxycodone and acetaminophen and affect the way Lynox works. Medications that can affect clearance include certain antifungal, antibiotic and HIV drugs.

Certain medications, such as naloxone, drastically reduce the levels of Lynox in the body. This sudden drop in Lynox levels will cause dependent individuals to experience withdrawal symptoms.

Lynox overdose is a serious, potentially fatal medical emergency. If you suspect you or someone you know is suffering from Lynox overdose, contact your local poison control center at 1-800-222-1222 or go to the nearest emergency room.

Doctors and nurses will administer drugs such as naloxone to lower Lynox levels in the blood, along with other emergency, life-saving treatments, like establishing an airway, pumping the stomach or performing CPR as necessary.

An individual may overdose on the opioid or the acetaminophen contained in Lynox. Both types of overdose are serious medical emergencies. Acetaminophen overdose and opioid overdose cause a different set of symptoms. Symptoms of acetaminophen overdose come in two waves. The first symptoms of acetaminophen overdose include:

  • Confusion
  • Loss of Appetite
  • Nausea
  • Stomach Pain
  • Sweating
  • Vomiting
  • Weakness

Later symptoms may include:

  • Dark Urine
  • Upper Abdominal Pain
  • Yellowing of the Skin or Eyes

Symptoms of opioid overdose include extreme drowsiness, muscle weakness, fainting, weak pulse, slow heart rate and coma. Other symptoms include pinpoint pupils, cold and clammy skin, blue lips, shallow breathing or no breathing at all.

The active ingredient in Lynox, oxycodone, is a favorite among recreational users because of the way narcotics get them high. Abusers get oxycodone on the street, by presenting fake prescriptions to pharmacies, getting prescriptions from multiple doctors or by stealing from friends, family members or even pharmacies and hospitals in a process the U.S. Drug Enforcement Agency, or DEA, calls "diversion."

Long-term Lynox abuse leads to physical dependence and addiction in some people.

You may experience unpleasant withdrawal symptoms when you stop taking Lynox, especially if you have been using high doses or taking this painkiller for a long time.

Withdrawal is a normal, predictable, physical sign of dependency, not necessarily a sign of willful abuse. Withdrawal symptoms are normal, physiological consequence of a sudden drop in the level of Lynox in the body of a person who is physically dependent on opioids.

Withdrawal presents itself in a variety of strong physical and psychological symptoms that can last five or more days as the levels of Lynox toxins slowly decrease; psychological symptoms of withdrawal may last much longer. Symptoms vary in intensity, depending on the duration of use and dosage strength. Overpowering and lengthy withdrawal symptoms may be severe enough to prevent you from quitting Lynox without the help of a qualified rehabilitation specialist.

The human body adapts to the presence of foreign substances in the body, including Lynox, by adjusting its own chemical balance to accommodate those drugs. The body even becomes tolerant of these substances, which means a person must take an ever-increasing amount of opioids to relieve pain or get high. With continuous use, the body may become dependent on the chemical, which means the individual must maintain a certain level of Lynox for the body to feel "normal." If the level of Lynox drops rapidly, the body struggles to maintain its chemical balance. This struggle manifests itself through uncomfortable, flu-like withdrawal symptoms.

Withdrawal symptoms include:

  • Agitation
  • Goosebumps
  • Nausea, Vomiting and Diarrhea
  • Runny Nose
  • Sweating

More about Lynox Withdrawal


Detoxification is the medical process of lowering opioid levels in a physically dependent body. Detoxification can occur either because the dependent person did not take enough Lynox, or because he has taken a medication to chemically reduce opioid levels. Detoxification in a dependent person will cause painful withdrawal symptoms, especially if the individual attempts self-detoxification without the help of medical professionals.

Dependence and addiction to Lynox is often difficult to overcome alone, especially if you have been taking large doses of Lynox or using this painkiller for a long time. Detoxification can be a grueling and unpleasant experience, especially for those who attempt self-detoxification.

Many medical professionals consider Rapid Detox the most humane and efficient way to detoxify the body from opioids such as Lynox. During the rapid detox process, board certified anesthesiologists administer sedatives and anesthesia along with the standard medications to bring opioids to safe levels. The patient rests in a comfortable "twilight sleep" during this process and awakens without any recollection of the withdrawal process. Learn More about Lynox Detoxification Programs
