What it is used for

NeoProfen is indicated to close a clinically significant patent ductus arteriosus (PDA) in premature infants weighing between 500 and 1500 g, who are no more than 32 weeks gestational age when usual medical management (e.g., fluid restriction, diuretics, respiratory support, etc.) is ineffective. The clinical trial was conducted among infants with an asymptomatic PDA. However, the consequences beyond 8 weeks after treatment have not been evaluated; therefore, treatment should be reserved for infants with clear evidence of a clinically significant PDA.

Who should not take it

NeoProfen is contraindicated in:

  • Preterm infants with proven or suspected infection that is untreated;
  • Preterm infants with congenital heart disease in whom patency of the PDA is necessary for satisfactory pulmonary or systemic blood flow (e.g., pulmonary atresia, severe tetralogy of Fallot, severe coarctation of the aorta);
  • Preterm infants who are bleeding, especially those with active intracranial hemorrhage or gastrointestinal bleeding;
  • Preterm infants with thrombocytopenia;
  • Preterm infants with coagulation defects;
  • Preterm infants with or who are suspected of having necrotizing enterocolitis;
  • Preterm infants with significant impairment of renal function.

Other medicines and interactions

  • Diuretics: Ibuprofen may reduce the effect of diuretics; diuretics can increase the risk of nephrotoxicity of NSAIDs in dehydrated patients. Monitor renal function in patients receiving concomitant diuretics.
  • Amikacin: Ibuprofen may decrease the clearance of amikacin.
