Background: Bronchodilators are the most commonly used drugs for Bronchial Asthma and COPD. Adverse Drug Reactions(ADR) of the Bronchodilators have been reported. Objectives: 

(i)To study the distribution pattern of adverse effects of bronchodilators at initiation or during the course of therapy (ii) To make a causality assessment of adverse effect identified using WHO ADR probability scale. (iii) To identify next drug tolerated better by him/her. Materials and Methods: An observational study lasted for duration of two months .Inclusion Criteria: All patients reporting ADR after initiation of bronchodilator or during the course of bronchodilator therapy for Bronchial Asthma/ COPD within the study period were included. The suspected adverse effect was noted and documented. Causality assessment based on WHO scale was employed. Results: During the study period, 10 patients reported to have ADR for bronchodilators were identified and WHO Causality Scale for ADR was applied  and the better drug tolerated by the patient could be noted. Conclusion: Inhalational formulations were better tolerated by the patients. Longer acting preparations were also better for the patients
