Adverse Drug Reactions (ADRs) constitute an enormous burden for the society. Due to the lack of knowledge and awareness, many ADRs remain unnoticed. Identification of ADRs and their reporting pattern can provide useful information for their management. Hence, this study was planned to evaluate pattern of ADRs. A total of 300 ADRs reports were analysed. The WHO (world health organisation) scale for causality assessment was used. Evaluation of the data was done for drug groups causing ADRs, body systems affected, reporters and seriousness of reactions.In the males the overall occurrence of ADRs was more. Skin was the most commonly affected organ system. Antimicrobials were the drug group most commonly responsible for causing ADRs. Upon causality assessment, majority of the ADRs were rated as probable.Most of the reports were contributed by the clinicians.
