Introduction. Polymedication or polypharmacy defines the use of several drugs at the same time, a phenomenon encountered more frequently among elderly people. Studies show that 90% of older adults use at least one medication weekly, and 40% - administer more than eight medications weekly. Pharmacists, together with other health specialists, contribute to minimizing the risks to which the elderly are subjected in the case of polymedication in outpatient settings. In this sense, the paper aims to evaluate the problems faced by the elderly in the use of medicines at home in order to develop behavioral algorithms in the provision of specialized geriatric pharmaceutical care. Material and methods. The intended descriptive study is ongoing. At this stage, 168 questionnaires intended for the elderly are collected, which contains 31 questions, describing the difficulties encountered by the elderly in administering medicines at home. Results. The results of the questionnaires’ analysis denote that in 60% of the answers, the elderly commit administration errors: on their initiative they change the treatment and his duration, the way of administration, and the doses of the medicines. More than 50% of the answers show that the elderly practice uncontrollable selfmedication and there are cases of polypharmacy, they are not physically able to administer the medicine and they do not read/understand the leaflet of the medicine. In about 30% of cases, the elderly administered expired medicines and gave their personal medicines to others. Conclusions. Administration errors are common among the elderly, and the implementation and application of specialized geriatric pharmaceutical care will help reduce their frequency.
