Objective: In this study, we surveyed the attitudes of community pharmacists regarding oral antidiabetic drugs that need to be continuously administered, focusing especially on recently available oral‐combination antidiabetic drugs, in terms of their positioning and medication adherence.　In addition, we identified relevant problems from the survey results and discussed the proper use of the combination drugs.Methods: We conducted a questionnaire‐based survey on health insurance‐covered dispensing pharmacies belonging to Kanazawa, Koga, Takasaki, Hitachi, and Hitachinaka Pharmaceutical Associations via fax or post from September 1, 2017 to November 30, 2017.Results: The overall response rate to the survey was 29.8%.　Although combination drugs were considered useful in terms of improved motivation to take medication, i.e., medication adherence, there were also opinions claiming that combination drugs are not particularly useful due to the following reasons: there are problems in discarding residual drugs, they are less economical than individual drugs, it is difficult to ingest tablets of combination drugs because of their large size, it is difficult to adjust doses of combination drugs, and medication adherence does not change because of concomitant drug use.Conclusion: Based on the results there was the opinion that a combination oral diabetes drug improves medication adherence but problems such as the generation of leftover unused drugs due to switching and an increase in the risk of overuse when taking medication was pointed out.　It is necessary for pharmacists to give advice in recognition of the risks with each active ingredient of the oral diabetes combination drug and to continuously monitor any development of side effects.　Furthermore, as with other diabetes remedies, pharmacists need to advise regarding the patient's lifestyle as well as monitor laboratory test results such as kidney function.　The patient's swallowing ability is also an important consideration at the time of medication instruction.
