Professional pharmaceutical care services contribute to better health problem control, especially in polymedicated patients, and to the optimization of health resources, which leads to less medication prescription and fewer visits to healthcare centers. This study included 78 patients, with the female sex being the most prevalent, with an average age of 72.49 ± 13.92 years; of these, 60 patients were over 65 years of age and, herefore, considered geriatric patients. They were included in a personalized medication dispensing service and, subsequently, a pharmacotherapeutic follow-up was carried out. 450 medication-related problems were detected, the most frequent of which were associated with the patient: lack of knowledge of use, poor therapeutic adherence, administration errors, etc., with the probability of presenting them being higher in the male sex. Associated with these medication problems, 160 negative medication-related results were detected; only 5 of them were not resolved during the study phase, the most frequent being those of non-quantitative ineffectiveness, that is, those that are not resolved with a modification of the pharmacological dose but by including or eliminating other active ingredients. In conclusion, the personalized medication dispensing service requires a medication review, such as pharmacotherapeutic follow-up, as both allow the optimization of the treatment of polymedicated patients, as well as an increase in the control of health problems.
