Background: Despite widespread phototherapy usage, many newborn infants remain in need of other lines of invasive therapy such as intravenous immunoglobulins and exchange transfusions.

Objective: To assess the efficacy and the safety of adding fenofibrate to phototherapy for treatment of pathological jaundice in full term infants.

Design/Methods: We conducted a double blinded randomized control study on 180 full-term infants with pathological unconjugated hyperbilirubinemia admitted to the NICU of Mansoura University Children's Hospital. They were randomly assigned to receive either oral fenofibrate 10 mg /kg /day for one day or two days or placebo. Primary outcome was total serum bilirubin values after 12, 24, 36, 48 hours from intervention. Secondary outcomes were total duration of treatment, need for exchange transfusions and intravenous immunoglobulin, exclusive breast-feeding on discharge, and adverse effects of fenofibrate.

Inclusion Criteria:

• we included appropriate for gestational age full-term infants with pathological unconjugated hyperbilirubinemia who are candidate for phototherapy according to American academy of pediatrics guidelines

Exclusion Criteria:

• Full term infants with intrauterine growth restriction, congenital malformations, conjugated hyperbilirubinemia, severe jaundice initially required exchange transfusion, skin abrasions or infection, and preterm infants were excluded
