WARNING:

Limitations of use

Prodeinextra should only be used if your doctor decides other treatment options are not able to effectively manage your pain or you cannot tolerate them.

Hazardous and harmful use

Prodeinextra contains codeine which may be habit forming. Prodeinextra poses risks of abuse, misuse and addiction which can lead to overdose and death. Your doctor will assess your risks and monitor you regularly during treatment.

Life threatening respiratory depression

Serious, life-threatening, or fatal respiratory depression (shallow or difficulty breathing) may occur with the use of Prodeinextra even when used as recommended. These problems can occur at any time during use, but the risk is higher when first starting Prodeinextra 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 Prodeinextra

Using Prodeinextra 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 minimize the dose and duration of use and monitor you regularly for signs and symptoms of breathing difficulties and sedation. You must not drink alcohol while taking Prodeinextra.

1. Why am I using Prodeinextra?

Prodeinextra contains the active ingredients paracetamol and codeine phosphate hemihydrate.

Prodeinextra is a type of analgesic. Paracetamol and codeine work together to stop the pain messages from getting through to the brain. Paracetamol also acts in the brain to help reduce fever.

Prodeinextra is used to relieve acute moderate pain and fever and is intended for short term use.

2. What should I know before I take Prodeinextra?

Pregnancy and breastfeeding

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

Do not take Prodeinextra during the third trimester of pregnancy.

Do not take it if you are in labour, especially if the baby is premature.

Prodeinextra contains codeine, which may produce withdrawal effects in the newborn baby.

Do not take it if you are breastfeeding or planning to breastfeed.

Prodeinextra passes into breast milk and there is a possibility your baby may be affected.

Addiction

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

Dependence

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

Tolerance

Tolerance to Prodeinextra may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.

Withdrawal

Continue taking your medicine for as long as your doctor tells you. If you stop having 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.

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

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may affect how Prodeinextra works. These include:

  • medicines causing sleepiness or drowsiness
  • tranquillisers (medicines for anxiety and nerves)

Boxed Warnings

Limitations of use. Because of the risks associated with the use of opioids, Prodeinextra 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. Prodeinextra 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 Prodeinextra. 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 taking Prodeinextra.

4 Clinical Particulars

4.9 Overdose

Elderly persons, small children, patients with liver disorders, chronic alcohol consumption or chronic malnutrition, as well as patients concomitantly treated with enzyme-inducing drugs are at an increased risk of intoxication, including fatal outcome.
Symptoms. Toxic symptoms include vomiting, abdominal pain, hypotension, sweating, central stimulation with exhilaration and convulsions in children, drowsiness, respiratory depression, cyanosis and coma. Nausea, vomiting, anorexia, pallor and abdominal pain generally appear during the first 24 hours of overdosage with paracetamol. Overdosage with paracetamol may cause hepatic cytolysis which can lead to hepatocellular insufficiency, gastrointestinal bleeding, metabolic acidosis, encephalopathy, disseminated intravascular coagulation, coma and death. Increased levels of hepatic transaminases, lactate dehydrogenase and bilirubin with a reduction in prothrombin level can appear 12 to 48 hours after acute overdosage. It can also lead to pancreatitis, acute renal failure and pancytopenia. The most serious adverse effect of acute overdosage of paracetamol is a dose dependent, potentially fatal hepatic necrosis. In adults, hepatotoxicity may occur after ingestion of a single dose of 10 to 15 g (30 tablets) of paracetamol; a dose of 25 g (50 tablets) or more is potentially fatal. Symptoms during the first two days of acute poisoning by paracetamol do not reflect the potential seriousness of the intoxication. Major manifestations of liver failure such as jaundice, hypoglycaemia and metabolic acidosis may take at least three days to develop.
In an evaluation of codeine intoxication in children, symptoms seen included: sedation, rash, miosis, vomiting, itching, ataxia and swelling of the skin. Respiratory failure may occur.
The ingestion of very high doses of codeine can cause initial excitation, anxiety, insomnia followed by drowsiness in certain cases, areflexia progressing to stupor or coma, headache, miosis, alterations in blood pressure, arrhythmias, dry mouth, hypersensitivity reactions, cold clammy skin, bradycardia, tachycardia, convulsions, gastrointestinal disorders, nausea, vomiting and respiratory depression.
Severe intoxication can lead to apnoea, circulatory collapse, cardiac arrest and death.
Treatment. Despite lack of significant early symptoms, patients should be referred to hospital urgently for immediate medical attention.
Consists primarily of management of paracetamol toxicity; naloxone is the treatment of choice for codeine intoxication. In cases of overdosage, methods of reducing the absorption of ingested drug are important. Prompt administration of 50 g activated charcoal and 500 mL iced mannitol 20% by mouth may reduce absorption.
Determinations of the plasma concentration of paracetamol are recommended.
Plasma concentration of paracetamol should be measured at 4 hours or later after ingestion (earlier concentrations are unreliable).
Where paracetamol intoxication is suspected, intravenous administration of SH group donators such as acetylcysteine within the first 10 hours after ingestion is indicated. Although acetylcysteine is most effective if initiated within this period, it can still offer some degree of protection if given as late as 48 hours after ingestion; in this case it is taken for longer.
If the history suggests that 15 g paracetamol or more has been ingested, administer one of the following antidotes.
Acetylcysteine 20% i.v. Administer 20% acetylcysteine (Parvolex, David Bull) immediately without waiting for positive urine test or plasma level results: initial dose 150 mg/kg over 15 minutes, followed by continuous infusion of 50 mg/kg in 500 mL 5% glucose over 4 hours and 100 mg/kg in 1 L 5% glucose over 16 hours; or
Oral methionine. 2.5 g immediately followed by three further doses of 2.5 g at four hourly intervals. For a 3 year old child, 1 g methionine 4 hourly for four doses has been used.
If more than ten hours have elapsed since the overdosage was taken, the antidote may be ineffective.
Relating to codeine component. In general, treatment should be symptomatic: re-establish adequate respiratory exchange by ensuring a clear airway and using mechanical ventilation. When treatment for paracetamol toxicity has been initiated the opioid antagonist naloxone hydrochloride is an antidote to respiratory depression; naloxone 400 microgram may be administered SC, IM or IV; IV may be repeated at intervals of 2 to 3 minutes if necessary. Assisted respiration may be required.
Further measures will depend on the severity, nature and course of clinical symptoms of intoxication and should follow standard intensive care protocols.
For information on the management of overdose, contact the Poisons Information Centre on 131126 (Australia).
