Comparative efficacy and safety of mezlocillin, cefoxitin, and clindamycin plus gentamicin in postpartum endometritis.

The efficacy of mezlocillin versus cefoxitin versus clindamycin plus gentamicin was evaluated in 152 patients with postpartum endometritis. There were no statistically significant differences in rate of cure among the three groups (87% with mezlocillin, 82% with cefoxitin, and 92% with clindamycin-gentamicin). There were no severe adverse reactions observed in any of the three treatment regimens. Mezlocillin is as safe and effective as cefoxitin and clindamycin-gentamicin for treatment of postpartum endometritis.
