Oral penicillin in the newborn.

This investigation was initiated to determine the optimal dose of oral peniciin required to give a satisfactory peniillin blood level in infants under a month old and to compare the relative efficcy of picillin and sulphathiazole paste in the treatment of minor skin lesions in infants during the neonatal period. The obvious advanta of penillin over other drugs are counterbalanced by the discomfort of intamusular injections and the possible danger of infection in the injection site. Oral penicillin is cleary preferable to intusular injection provided adequate blood levels are attained.
