Antimicrobials are used to treat infectious diseases. However, antimicrobial agents are frequently prescribed in excess, which leads to antimicrobial resistance. As a result, the prescribing pattern of antimicrobial agents must be evaluated. The study included 100 patients. The study lasted 6 months in a tertiary health care hospital. This is a Prospective observational study. Among 100 patients, 51 were male and 49 were female. Most of patients were between the age group of 51- 60 and 61-70 (20%) in each group. The most frequently seen infectious diseases were LRTI (39%), UTI (25%), GE (13%), Dengue (6%), Sepsis (6%). The length of hospital stay in LRTI patients for less than 4 days was 41.04% and more than 4 days was 58.96%. The length of hospital stay in UTI patients for less than 4 days was 44% and more than 4 days was 56%. The most common antibiotics used were Cefoperazone-Sulbactam (25.49%) followed by Ceftriaxone (21.38%) and Oseltamivir (10.98%).
 In Lower Respiratory Tract Infection (LRTI) the most commonly used antimicrobial agents are Ceftriaxone (25.92%) and Oseltamivir (20.98%). In Urinary Tract Infection (UTI) the most commonly used antimicrobial agent is Cefoperazone-Sulbactam (48.29%). Ceftriaxone (22.72%) and Cefpodoxime (9.09%) are used for the treatment of Gastroenteritis (GE).
