Topical eardrops are commonly prescribed by otolaryngologists and general practitioners and many believe that patient compliance is poor, although this has not been studied in a properly controlled manner. Thirty-nine patients with otitis externa were reviewed four times during a two-week course of topical eardrops and their treatment compliance studied. The patients tended to undermedicate themselves, and this tendency increased over the two-week period. Patients were administering significantly fewer drops by the end of day 11 than by the end of day 3 (p = 0.2). Compliance patterns were extremely poor, in that only 40 per cent of patients were managing to self-medicate within a 25 per cent error margin by the end of day 3. These findings may have future implications in the ongoing debate on eardrop use.
