Consumer Medicine Information

Limitations of use
OXYCODONE VIATRIS 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
OXYCODONE VIATRIS 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
OXYCODONE VIATRIS 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 OXYCODONE VIATRIS 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 OXYCODONE VIATRIS
Using OXYCODONE VIATRIS 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 OXYCODONE VIATRIS.

What is in this leaflet

This leaflet answers some common questions about OXYCODONE VIATRIS. 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 the risks of you taking OXYCODONE VIATRIS 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 need to read it again.

What OXYCODONE VIATRIS is used for

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

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

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 this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.

You can become addicted to OXYCODONE VIATRIS even if you take it exactly as prescribed. OXYCODONE VIATRIS 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 OXYCODONE VIATRIS. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking OXYCODONE VIATRIS suddenly, so it is important to take it exactly as directed by your doctor.

Tolerance to OXYCODONE VIATRIS 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

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