Symptomatic treatment of pain of moderate or intense intensity or not responding to the use of peripheral analgesics used alone.

Against indications

· Child under 15 kg.


· Hypersensitivity to paracetamol or other components.

· Hepatocellular insufficiency.


· Codeine is contraindicated in patients with respiratory insufficiency regardless of the degree of respiratory failure, due to the depressant effect of codeine on respiratory centers.

· Asthma.

· Hypersensitivity to codeine.

· During breastfeeding apart from a punctual intake (see section Pregnancy and breastfeeding ).


The PRAC initiated in November 2012 a re-evaluation of codeine-based medicines used as analgesics in children 5. Codeine is transformed into morphine in the body by a liver enzyme called cytochrome P450 CYP2D6. However, the activity of this enzyme can vary depending on the individual; some patients have a profile of CYP2D6 rapid metabolizers, which results in a faster conversion of codeine to morphine. In these patients, blood levels of morphine are higher, posing a toxic risk, including a risk of respiratory failure.

The observation in the United States of an increased risk in children who received codeine after surgery (tonsillectomy and adenoidectomy) is the cause of the alert. A very small number of serious or even fatal cases of respiratory depression have been reported in children with "rapid metabolisers".

Without waiting for the final decision of the risk minimization measures announced, the ANSM already recommends: to use codeine in children over 12 years old only after failure of paracetamol and / or NSAIDs.

- no longer use this product in children under 12 years;

- no longer use this product after tonsillectomy or adenoidectomy;

- no longer use this product in breastfeeding women

ANSM alert of 12/05/2015:

The CMDH also endorsed the PRAC recommendation to contraindicate codeine in patients known to be ultra-fast metabolisers of CYP2D6 substrates. In addition, the CMDH recommends extending the contraindication during breastfeeding to all adult codeine-containing specialties, regardless of indication.

Pending the modification of the marketing authorizations concerned, the ANSM recommends taking into account these restrictions of use right now.
