Fever is a sign of an underlying illness. It is more important to treat the underlying illness than the fever itself. Fever is reduced to make the child more comfortable. The two most used antipyretics (paracetamol and ibu-profen) are also analgesics.
Paracetamol is the drug of choice. It is less likely to be associated with a significant ADR than ibuprofen. Ibuprofen is appropriate to use as an antipyretic agent if paracetamol has failed. Although the safest of all NSAIDs, it should not be used in children with gastroenteritis or other GI symptoms.
