True / False
Is contraindicated in CYP2D6 rapid metabolisers Correct
Has a recommended maximum daily dose of 120 mg in children age 12-18 years Incorrect answer selected
Is recommended after tonsillectomy for obstructive sleep apnoea in children over the age of 5 years Correct
Should be avoided in children under 12 years Correct
Is recommended for breastfeeding mothers Correct
Explanation
Codeine is a prodrug converted to morphine in the liver by CYP2D6 enzyme. Known CYP2D6 rapid metabolisers are at risk of toxic blood levels of morphine.
A recent European review of morphine toxicity in children receiving codeine for pain after surgery has resulted in new recommendations that codeine should be avoided for acute analgesia in all children under 12 years (thus also in breastfeeding mothers as morphine passes into breast milk) and avoided if possible in older children. Moreover, it is contraindicated in all children under 18 years of age for adenotonsillectomy in the treatment of obstructive sleep apnoea.
The maximum daily dose in children 12-18 years is 240 mg.
