Objective: To determine what should be done as a preventive medicine physician by analysing the effect of polypharmacy and herbal treatment.

Methods: This survey-based, cross-sectional study was carried out at Istanbul Okmeydani Training and Research Hospital, Istanbul, Turkey, from February to May 2015, and comprised patients using two or more medicines at full strength for at least 240 days. The patients were classified into two groups. Group A comprised those who were using less than 4 medications (at least 2), while group B comprised patients using more than 4 medications. The short version of World Health Organisation's quality-of-life questionnaire was applied. SPSS 22 was used for data analysis.

Results: Of the 350 participants, 106(30.3%) were receiving herbal treatment while 244(69.7%) had no such treatment. Group B patients had meaningfully lower scores for body, spiritual, social and external environment (p=0.001). Moreover, the patients having no herbal or supportive treatment scored significantly higher in the physical, spiritual, social relations and external environment (p=0.001). In group A, patients receiving no herbal treatment scored meaningfully higher in all fields, including physical (p=0.009), social relations (p=0.043) and external environment (p=0.001).

Conclusions: Old age, living alone, level of education, having a regular monthly income, the number of drugs used, chronic diseases and herbal treatments affected the life quality.
