Physiologic jaundice usually does not require medication. However, the diagnosis of physiologic jaundice can only be confirmed after pathologic jaundice has been excluded. Physiologic jaundice is the appearance of jaundice in full-term infants 2-3 days after birth, peaking at 4-5 days and subsiding at 5-7 days, not later than two weeks. The daily rise in serum bilirubin is less than 85.5 umol/L and less than 221 umol/L in full-term infants, whereas in pathological jaundice, the jaundice appears too early, within 24 hours after birth, and the value of bilirubin rises too quickly, to more than 85.5 umol/L daily or more than 220.6 umol/L serum bilirubin.
