This is a case review of two infants who received a prolonged course of prostaglandin-E2 therapy for congenital cardiac lesions while awaiting corrective surgery. These cases highlight an association between prolonged prostaglandin-E2 therapy with periosteal reactions and elevated C-reactive protein levels. Failure to recognise this association may lead to multiple courses of antibiotics for presumed sepsis and further prolongation of prostaglandin-E2 therapy.
