1. Why am I using Oxycodone hydrochloride solution for injection or infusion?

Oxycodone hydrochloride solution for injection or infusion contains the active ingredient oxycodone hydrochloride. Oxycodone hydrochloride solution for injection or infusion is opioid analgesics.

Oxycodone hydrochloride solution for injection or infusion is used to relieve short-term management of severe pain for which other treatment options have failed or are otherwise inappropriate to provide sufficient management of pain.

Ask your doctor if you have any questions about why it has been prescribed for you.

As with all strong painkillers, your body may become used to you having oxycodone. Being given it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop having oxycodone suddenly, so it is important that you are given Oxycodone hydrochloride solution for injection or infusion exactly as directed by your doctor.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

This medicine is not recommended to be used during labour.

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

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Oxycodone can pass into the breast milk and can affect the baby. Your doctor can discuss the risks involved.

If you have not told your doctor about any of the above, tell them before you have Oxycodone hydrochloride injection or infusion.

You should not be given this medicine if you are pregnant or intend to become pregnant.

Boxed Warnings

Limitations of use. Because of the risks associated with the use of opioids, Oxycodone hydrochloride injection or infusion should only be used in patients for whom other treatment options, including non-opioid analgesics, are ineffective, not tolerated or otherwise inadequate to provide appropriate management of pain (see Section 4.4 Special Warnings and Precautions for Use).
Hazardous and harmful use. Oxycodone hydrochloride injection or infusion poses risks of hazardous and harmful use which can lead to overdose and death. Assess the patient's risk of hazardous and harmful use before prescribing and monitor the patient regularly during treatment (see Section 4.4 Special Warnings and Precautions for Use).
Life threatening respiratory depression. Serious, life-threatening or fatal respiratory depression may occur with the use of Oxycodone hydrochloride injection or infusion. Be aware of situations which increase the risk of respiratory depression, modify dosing in patients at risk and monitor patients closely, especially on initiation or following a dose increase (see Section 4.4 Special Warnings and Precautions for Use).
Concomitant use of benzodiazepines and other central nervous system (CNS) depressants, including alcohol. Concomitant use of opioids with benzodiazepines, gabapentinoids, antihistamines, tricyclic antidepressants, antipsychotics, cannabis or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Limit dosages and durations to the minimum required; and monitor patients for signs and symptoms of respiratory depression and sedation. Caution patients not to drink alcohol while on Oxycodone hydrochloride injection or infusion.

4 Clinical Particulars

4.9 Overdose

Symptoms. Acute overdosage with oxycodone can be manifested by respiratory depression (reduced respiratory rate and/or tidal volume, cyanosis), extreme somnolence progressing to stupor or coma, hypotonia, miosis (dilated if hypoxia is severe), cold and/or clammy skin, and sometimes bradycardia, hypotension, pulmonary oedema, and death. Severe overdose may result in apnoea, pulmonary oedema, circulatory collapse and death. Toxic leukoencephalopathy has been observed with oxycodone overdose.
Treatment of oxycodone overdosage. Primary attention should be given to immediate supportive therapy with the establishment of adequate respiratory exchange through the provision of a patent airway and institution of assisted or controlled ventilation. Adequate body temperature and fluid balance should be maintained. Oxygen, intravenous fluids, vasopressors and other supportive measures should be used as indicated, to manage the circulatory shock accompanying an overdose. Cardiac arrest or arrhythmias may require cardiac massage or defibrillation.
If there are signs of clinically significant respiratory or cardiovascular depression, the use of an opioid antagonist should be considered. The opioid antagonist naloxone hydrochloride is a specific antidote against respiratory depression due to overdosage. Concomitant efforts at respiratory resuscitation should be carried out. The patient should be under continued surveillance and doses of the antagonist should be repeated as needed to maintain adequate respiration.
For massive overdosage, associated with clinically significant respiratory or cardiovascular depression, 0.8 mg naloxone may be administered intravenously, repeating at 2-3-minute intervals as necessary, or by a titrated infusion of 2 mg in 500 mL of normal saline or 5% dextrose (0.004 mg/mL). The infusion should be run at a rate related to previous bolus doses administered and should be in accordance with the patient's response. However, because the duration of action of naloxone is relatively short, the patient must be carefully monitored until spontaneous respiration is reliably re-established.
Monitoring for a further 24-48 hours is then recommended in case of possible relapse. Please see naloxone hydrochloride injection Product Information for further information.
In an individual physically dependent on, or tolerant to, opioids, the administration of the usual dose of opioid antagonist will precipitate an acute withdrawal syndrome. The severity of this syndrome will depend on the degree of physical dependence and the dose of antagonist administered. The use of opioid antagonists in such individuals should be avoided if possible. If an opioid antagonist must be used to treat serious respiratory depression in the physically dependent patient, the antagonist should be administered with extreme care by using dosage titration, commencing with 10 to 20% of the usual recommended initial dose.
Toxicity. Oxycodone toxicity may result from overdosage but because of the great inter-individual variation in sensitivity to opioids it is difficult to determine an exact dose of any opioid that is toxic or lethal. The toxic effects and signs of overdosage may be less pronounced than expected when pain and/or tolerance are manifest.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Oxycodone was not genotoxic in bacterial gene mutation assays but was positive in the mouse lymphoma assay. In assays of chromosomal damage, genotoxic effects occurred in the human lymphocyte chromosomal assay in vitro, but not in the in vivo bone marrow micronucleus assay in mice.
Carcinogenicity. Carcinogenicity was evaluated in a 2-year oral gavage study conducted in Sprague-Dawley rats. Oxycodone did not increase the incidence of tumours in male and female rats at doses up to 6 mg/kg/day (equivalent to 6.8 mg/day in men and 24.6 mg/day in women, based on estimated AUC values). The doses were limited by opioid-related pharmacological effects of oxycodone.
