Oxycontin is part of the drug class:

  • Natural opium alkaloids

Oxycontin Precautions

  • Do not drive, operate heavy machinery, or participate in any other possibly dangerous activities until you know how you react to this medicine. This medication can make you sleepy.
  • Do not drink alcohol while using Oxycontin. It may increase the chance of getting dangerous side effects.
  • Do not take other medicines without your doctor’s approval. Other medicines include prescription and non-prescription medicines, vitamins, and supplements. Be especially careful about products that make you sleepy.

Do not take Oxycontin if:

  • your doctor did not prescribe it for you
  • are allergic to any of its ingredients
  • have had a severe allergic reaction to a medicine that contains oxycodone. Ask your healthcare provider if you are not sure.
  • are having an asthma attack or have severe asthma, trouble breathing, or any lung problems
  • have a bowel blockage called paralytic ileus
  • have recently had a head injury
  • you have a history of drug or alcohol dependence
  • you have had a severe allergic reaction to codeine, hydrocodone, dihydrocodeine, or oxycodone (such as Tylox, Tylenol with Codeine, or Vicodin). A severe allergic reaction includes a severe rash, hives, breathing problems, or dizziness.

Oxycontin can cause serious breathing problems that can become life-threatening, especially if Oxycontin is used the wrong way. Call your healthcare provider or get medical help right away if:

  • your breathing slows down
  • you have shallow breathing (little chest movement with breathing)
  • you feel faint, dizzy, confused, or
  • you have any other unusual symptoms

Oxycontin can cause your blood pressure to drop. This can make you feel dizzy and faint if you get up too fast from sitting or lying down. Low blood pressure is also more likely to happen if you take other medicines that can also lower your blood pressure. Severe low blood pressure can happen if you lost blood or take certain other medicines.

There is a chance of abuse or addiction with Oxycontin. The chance is higher if you are or have been addicted to or abused other medicines, street drugs, or alcohol, or if you have a history of mental problems.

Oxycontin and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Oxycontin falls into category B. There are no well-done studies that have been done in humans with Oxycontin. But in animal studies, pregnant animals were given this medication, and the babies did not show any medical issues related to this medication.

Oxycontin Usage

Oxycontin comes as an extended-release tablet and is taken every 12 hours.

The instructions for use will vary depending on which form of the medication you have been prescribed. Follow the directions carefully.

Oxycontin may cause stomach upset. Taking it with food may help.

If you miss a dose, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once unless your doctor tells you to.

Oxycontin Dosage

Take Oxycontin exactly as prescribed by your doctor. Follow the directions on your prescription label carefully. Your doctor will determine the best dose for you. The dosage of Oxycontin must be individualized.

Before Using Oxycontin

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of Oxaydo®, Roxicodone®, and Xtampza™ ER in the pediatric population. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of Oxycontin® in children. However, safety and efficacy have not been established in children younger than 11 years of age.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of oxycodone in the elderly. However, elderly patients are more likely to have age-related lung, liver, or kidney problems, which may require caution and an adjustment in the dose for patients receiving oxycodone in order to avoid potentially serious side effects.

Breast Feeding

Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using this medicine.

Proper Use of oxycodone

This section provides information on the proper use of a number of products that contain oxycodone. It may not be specific to Oxycontin. Please read with care.

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of this medicine is taken for a long time, it may become habit-forming (causing mental or physical dependence).

This medicine comes with a Medication Guide and a patient information leaflet. Read and follow these instructions carefully. Ask your doctor if you have any questions.

Oxycodone extended-release capsules or tablets should only be used by patients who have already been taking narcotic pain medicines, also called opioids. These patients are called opioid-tolerant. If you are uncertain whether or not you are opioid-tolerant, check with your doctor before using this medicine.

Measure the oral liquid concentrate with the calibrated dropper that comes with the package. Your doctor may have you mix the concentrate with a small amount of liquid or food. Carefully follow the instructions and take the medicine mixture right away.

Measure the oral liquid with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.

Swallow the Oxaydo® or OxyContin® tablet whole with water. Do not break, crush, cut, chew, or dissolve it. Do not pre-soak, lick, or wet the tablet before placing it in the mouth. Take one tablet at a time. Also, do not give this medicine through nasogastric or feeding tubes.

If you are using the extended release capsules:

  • Take this medicine with food and with approximately the same amount of food each time.
  • If you have trouble swallowing, you may open the capsule and sprinkle the contents on soft foods (eg, applesauce, pudding, ice cream, or jam) or into a cup and then give it directly into the mouth and swallow immediately. Drink a glass of water to make sure all medicine has been taken.
  • This medicine may also be given through a feeding tube.

Oxycodone extended-release capsules or tablets work differently from the regular oxycodone oral solution or tablets, even at the same dose. Do not switch from one brand or form to the other unless your doctor tells you to.

Dosing

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

Important information

You should not use OxyContin if you have severe asthma or breathing problems, or a blockage in your stomach or intestines.

Oxycodone can slow or stop your breathing.

Oxycodone may be habit-forming, even at regular doses. Take this medicine exactly as prescribed by your doctor. Never share the medicine with another person. MISUSE OF NARCOTIC PAIN MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.

Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.

How it works

  • OxyContin is a brand (trade name) of controlled-release oxycodone. OxyContin releases oxycodone slowly over a period of 12 hours.
  • Oxycodone is a morphine-like, strong pain-relief medicine used for the relief of severe pain that is unresponsive to less potent pain-relief medicines (analgesics). Oxycodone is relatively selective for the mu opioid receptor, although it may bind to other opioid receptors at higher dosages. Oxycodone is a full agonist at the mu receptor (full agonists have a larger effect at higher dosages).
  • OxyContin belongs to the group of drugs known as opioids or opioid analgesics. Oxycontin may also be called a narcotic analgesic.
