Male patient experiencing ADR were more (73, 55.7%) than female (58, 44.2%). Adult patients (12-60 years) experienced 110 (84%) ADR followed by pediatric patients (< 12 years) 11 (8.4%) and geriatric patients (>60 years) 10 (7.63%). Antimicrobial were the most common group of drugs responsible for ADR followed by NSAIDs and antipsychotic group.Conclusions: Present study shows lack of awareness among health care professionals for reporting of an ADR.
