Oxyfast 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 oxycodone. 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 oxycodone 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.

Oxycodone can cause serious breathing problems that can become life-threatening, especially if oxycodone 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

Oxycodone 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 oxycodone. 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.

 

Oxyfast 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.

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

Oxyfast and Lactation

Oxycodone has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from oxycodone, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.

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 Oxyfast. 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.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using Oxyfast

It is very important that your doctor check your progress while you are taking this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.

Do not use this medicine if you are using or have used an MAO inhibitor within the past 14 days.

This medicine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Do not use more of this medicine or take it more often than your doctor tells you to. This can be life-threatening. Symptoms of an overdose include extreme dizziness or weakness, slow heartbeat or breathing, seizures, trouble breathing, and cold, clammy skin. Call your doctor right away if you notice these symptoms.

This medicine will add to the effects of alcohol and other CNS depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop using this medicine. Check with your doctor before taking any of these medicines while you are using this medicine.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.

This medicine may make you dizzy, drowsy, or lightheaded. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.

Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

If you have been using this medicine regularly for several weeks or longer, do not change your dose or suddenly stop using it without checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the possibility of withdrawal symptoms, such as abdominal or stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble sleeping.

Using this medicine while you are pregnant may cause serious unwanted effects in your newborn baby. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using this medicine.

Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of certain medical tests.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
