The use of pressurised metered dose inhalers was assessed among 93 asthmatic patients attending the respiratory out patient clinic between January to October 1989. They were regular users of the inhalers prior to the assessment. 62.4% of the patients were found to use the inhalers incorrectly. Forty three percent made more than one error. The commonest error observed was the failure to actuate and inhale the aerosol together in 41.9%. There was no difference in the occurrence of incorrect performance between different sexes, age groups, duration of inhaler used and previous supervision or no supervision by the doctors.
