Background: Urinary Tract Infection (UTI) may be classified as lower (cystitis and asymptomatic bacteriuria) or upper urinary tract infections (pyelonephritis). The recommended antibiotics for use in pregnancy for management of ASB include amoxicillin, oral cephalosporins and nitrofurantoin; and for the treatment of lower UTI during pregnancy include penicillins, oral cephalosporins. Data from the antibiotic usage study in UTI during pregnancy will help in establishing a proper antibiotic utilisation guideline and promotes rational prescribing of medicines. Aim: To study the antimicrobial prescription practices for urinary tract infection during pregnancy. Materials & Methods: The study was conducted in the Department of Pharmacology and Department of Obstetrics & Gynaecology, Himalayan Institute of Medical Sciences (HIMS), Dehradun, over a period of 12 months. This was an observational cross sectional study done in 45 pregnant women with or without symptoms of UTI. Results: 29.4% of the pregnant women with symptomatic UTI were culture positive while all were culture positive who had asymptomatic UTI. Cephalosporins were most frequently prescribed followed by nitrofurantoin. Conclusion: Urine culture should be performed as a screening and diagnostic tool for UTI during pregnancy. Various classes of antimicrobials were being prescribed for UTI during pregnancy.
