Paracetamol was reported to be effective for patent ductus arteriosus (PDA) closure. We present a case series of PDA closure by paracetamol in seven premature infants. During the treatment, paracetamol blood levels did not exceed the recommended levels for analgesia and hyperthermia in six tested infants. None of the patients demonstrated significant disturbances of liver function.
