Management of bacteriuria in pregnancy

Abstract

Bacteriuria of pregnancy is a common condition which, although usually asymptomatic, may give rise to potentially serious sequelae. All pregnant women should therefore be screened for the presence of bacteriuria, which if detected should be treated with an antimicrobial agent believed to be safe for use in pregnancy. Appropriate antimicrobial drugs include penicillins, cephalosporins and nitrofurantoin. Nalidixic acid, aminoglycosides and sulphonamides may be used under certain circumstances and with some precautions. Tetracyclines, trimethoprim and co-trimoxazole (trimethoprim-sulphamethoxazole) should be avoided. There is some evidence that short-course therapy in pregnant women is less effective than longer courses, and we continue to recommend a 7-day course. Follow-up after completing a treatment course is an essential part of managing bacteriuria of pregnancy.
