oxycodone hydrochloride

Consumer Medicine Information

Limitations of use
Oxyndone should only be used when your doctor decides that other treatment options are not able to effectively manage your pain or you cannot tolerate them.
Hazardous and harmful use
Oxyndone poses risks of abuse, misuse and addiction which can lead to overdose and death. Your doctor will monitor you regularly during treatment.
Life threatening respiratory depression
Oxyndone can cause life-threatening or fatal breathing problems (slow, shallow, unusual or no breathing), even when used as recommended. These problems can occur at any time during use, but the risk is higher when first starting Oxyndone and after a dose increase, if you are older or have an existing problem with your lungs. Your doctor will monitor you and change the dose as appropriate.
Use of other medicines while using Oxyndone
Using Oxyndone with other medicines that can make you feel drowsy such as sleeping tablets (e.g. benzodiazepines), other pain relievers, antihistamines, antidepressants, antipsychotics, gabapentinoids (e.g. gabapentin and pregabalin), cannabis and alcohol may result in severe drowsiness, decreased awareness, breathing problems, coma and death.
Your doctor will minimise the dose and duration of use; and monitor you for signs and symptoms of breathing difficulties and sedation. You must not drink alcohol while using Oxyndone.

What is in this leaflet

This leaflet answers some common questions about Oxyndone. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed up the risks of you taking oxycodone against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may want to read it again later.

What Oxyndone is used for

This medicine is used for the short term management of severe pain.

This medicine belongs to a group of medicines called narcotic analgesics.

This medicine contains oxycodone hydrochloride as the active ingredient.

The active ingredient in this medicine works by binding to receptors called opioid receptors, which are in your central nervous system. This binding action changes your body’s perception of pain throughout the central nervous system producing the pain relieving (analgesic) effect.

Ask your doctor if you have any questions about why Oxyndone has been prescribed for you. Your doctor may have prescribed it for another reason.

Oxyndone is only available with a doctor’s prescription.

You can become addicted to Oxyndone even if you take it exactly as prescribed. Oxyndone may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.

As with all other opioid containing products, your body may become used to you taking Oxyndone. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking Oxyndone suddenly, so it is important to take it exactly as directed by your doctor.

Tolerance to Oxyndone may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect. Speak to your doctor if this occurs.

Continue taking your medicine for as long as your doctor tells you. If you stop taking this medicine suddenly, your pain may worsen and you may experience some or all of the following withdrawal symptoms:

  • nervousness, restlessness, agitation, trouble sleeping or anxiety
  • body aches, weakness or stomach cramps
  • loss of appetite, nausea, vomiting or diarrhoea
  • increased heart rate, breathing rate or pupil size
  • watery eyes, runny nose, chills or yawning
  • increased sweating

Oxyndone given to the mother during labour can cause breathing problems and signs of withdrawal in the newborn.
