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?

  • you have unstable asthma or emphysema, respiratory depression (shallow breathing) or respiratory insufficiency (difficulty breathing).
  • you have bronchitis
  • you have liver failure
  • you have Glucose-6-phosphate-dehydrogenase deficiency (an enzyme deficiency)
  • you are a known CYP 2D6 ultra-rapid metaboliser (a fast metaboliser of codeine by the CYP 2D6 enzyme)

Do not take it if the packaging is damaged or shows signs of tampering.

Check with your doctor or pharmacist if you have or have had any of the following medical conditions:

  • heart, lung, liver or kidney problems
  • low blood pressure
  • difficulty breathing, wheezing, chronic cough, asthma, or other chronic breathing conditions

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.


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.


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 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.


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?
