The aim of this study was to evaluate the effect of nursing interventions applied to elderly individuals to improve rational use of medicines (RUM) and awareness through home visits. It was carried out in a prospective, randomized controlled experimental design with the pretest-post-test control group. The study was completed with 74 elderly individuals aged [greater than or equal to]65 years living in a rural area. The intervention group received education, counselling, brochures and pill boxes through home visits to increase RUM and awareness. The study data were collected between September and December 2022 using the face-to-face interview method, the elderly identification form, the Rational Use of Medicines Scale and the Rational Drug Use Awareness Scale. After nursing interventions were applied at home, it was determined that, the mean scores of RUM and Awareness of RUM of the intervention group increased compared to the control group and that, interventions to improve RUM and awareness were effective. In line with these results, training sessions on RUM should be organized periodically for elderly individuals and home visits should be planned by nurses at regular intervals to ensure the sustainability of RUM in the home environment.
