Cephalexin: clinical and laboratory evaluation in infants and children.

Cephalexin appears to be a highly effective antibiotic. It possesses the qualities of rapid oral absorption, production of high drug levels in the blood and urine, and near absence of side effects. It is effective against infections due to gram-positive cocci infections, with the exception of Enterococcus, and for most infections caused by E. coli and Klebsiella. It is useful in the treatment of a wide variety of infections in infants and children, and particularly valuable with susceptible infections in patients who do not require parenteral antimicrobial therapy.
