PATIENT MEDICATION

Oxycodone

 

What is oxycodone?

Oxycodone is an opioid medicine used to control pain. Oxycodone is available in many forms, all taken by mouth:

  • Fast-acting 5-mg white tablet and clear liquid (known as Roxicodone®)
  • A long-acting 10-mg white tablet, 20-mg pink tablet, 40-mg yellow tablet, and 80-mg green tablet (known as Oxycontin®)
  • A fast-acting combination with acetaminophen (Percocet®, Endocet®)

Laboratory testing for oxycodone

An enzyme in the body called cytochrome P450 2D6 (CYP2D6) has the ability to break down certain medicines including oxycodone. A genetic test can be done to determine if your CYP2D6 breaks down medicines slower or faster than normal. If your body breaks down the medicine slower or faster than normal, you should avoid taking oxycodone. For information about CYP2D6 and its effect on oxycodone, talk with your doctor or pharmacist, and see “Do you know… Cytochrome P450 2D6 (CYP2D6) and medicines.” For more details, go to www.stjude.org/pg4kds.

How to take oxycodone

  • If you are only taking the fast-acting form of oxycodone, you will probably need to take the medicine every 2 to 6 hours to relieve pain. Keep a record of the number of tablets or the amount of liquid medicine you take each day. Take this record to the clinic. This record will help your doctor give you the best possible pain control.
  • If you are taking both the fast-acting and long-acting forms of oxycodone, you may only need to take the fast-acting form occasionally for “breakthrough” pain.
  • If you are taking the long-acting form of oxycodone, you must take it on a regular schedule to receive the best pain relief. Long-acting oxycodone is usually taken every 8 to 12 hours.
  • Do not cut, chew, or crush the long-acting tablets. Swallow them whole.
  • If stomach upset occurs, take oxycodone with food.
  • If you are taking oxycodone with acetaminophen, do not take extra acetaminophen (Tylenol®) or medicines containing acetaminophen. This could result in a dose of Tylenol® that is too high.

Special instructions for oxycodone

  • If you have any of the side effects listed above, most should decrease after you have taken oxycodone for a couple of days. Tell your doctor if the side effects increase while taking this medicine. It may mean you need less oxycodone.
  • If you are taking this medicine regularly, do not stop this medicine until the doctor tells you to do so. Stopping oxycodone without slowly decreasing the dose can lead to diarrhea, headache, sweating, muscle cramps, trouble sleeping, nausea, vomiting, or feeling restless.
  • This medicine may cause you to feel dizzy or drowsy. Oxycodone may impair your ability to drive a car or operate heavy machinery. Do not take part in these activities if you are sleepy, drowsy, dizzy, or not alert after taking oxycodone.
  • If you have missed sleep because of your pain, when you start this medicine you may sleep more for the first few days to “catch up” on missed sleep.
  • If you are taking this medicine regularly, then you should drink more fluid and eat more fiber to help prevent constipation. Tell your doctor or nurse if you have not had a bowel movement in 3 to 5 days. You may need to take a stool softener or laxative to relieve your constipation.
  • If you have taken oxycodone for a long time, your doctor may slowly decrease your dose to wean you off oxycodone. During this time, watch for a sudden onset of diarrhea, headache, sweating, muscle cramps, trouble sleeping, nausea, vomiting, or feeling restless. If these symptoms occur, call your doctor right away. It could mean your dose is being decreased too fast.
  • Other medicines can increase the drowsy feeling caused by oxycodone. These medicines include:
    • Alcohol (found in many over-the-counter cough and cold medicines)
    • Diphenhydramine (over-the-counter Benadryl®)
    • Promethazine
    • Diazepam or lorazepam
