Medication errors have been occurring when various liquids in containers resembling those for ophthalmic solutions are mistaken for eye drops. Usually, hospital-prepared ear and nose drops are put in containers used for ophthalmic solutions, and the formulation is indicated on the label. However, this makes ear, nose, and eye drops look quite similar outwardly and it is easy for the patient to use them for the wrong purpose. Based on an examination of the containers and labeling of the different types of drops with respect to safety, we changed the container for the nose drops to an atomizer but we were not able to change the container for the ear drops. As a solution, we designed a "mark for prevention of misuse" and displayed it on the label. To evaluate the usefulness of the mark, we conducted a questionnaire survey of outpatients. Fifty percent of the patients reported that they knew the effects of the drugs prescribed to them and 85% of patients responded that it was necessary to have "indications and effects" on drug labels. These responses suggest that indicating the effect of a drug is useful because it improves patients' ability to distinguish between drugs. Furthermore, eighty percent of the patients said that the "mark for prevention of misuse" was necessary. From the viewpoint of risk management, 85% of the patients responded that it was a good idea to have the mark on the label. The results of the present study indicate that the measures we adopted were effective.
