A condition that may occur when chloramphenicol levels exceed 70 µg/mL; premature infants are most susceptible, given their limited capacity to glucuronidate and excrete chloramphenicol, the functional deficiency in glucuronyl transferase activity corrects itself within the first 3–4 wks of life; high levels of chloramphenicol inhibit mitochondrial electron transport, disrupting energy metabolism; in children < 1 month of age, doses should be 25 mg/kg
