Warnings & precautions in children

When prolonged treatment is given to children, the growth should be checked carefully because of the possibility of growth inhibition. Regular echocardiographic examination is needed in infants and young children because long-term use at higher than recommended doses can cause reversible myocardial hypertrophy.

Severe icterus has been observed with concomitant use of tetracosactide and valproate in children. These two drugs must not be used together. [SmPC Synacthen]
