Background: Discarding pharmaceuticals in the garbage or into the sewage system are still the most common methods in many countries. This study aims to investigate the guidance provided by pharmacists to customers on the disposal of unused and expired household medications in São Paulo State, Brazil. Method: The study population consisted of 630 pharmacists from the State of São Paulo, the majority were women under 60 years old, who work in pharmacies that dispense commercial drugs. They answered an online questionnaire with questions composed in three blocks: demographic, work, and academic information on the pharmacist; the disposal of household medications; and the reverse logistics of these medications. An invitation to participate in the questionnaire was made via WhatsApp, individually and collectively. Inferential statistics were performed using the chi-square test, and were considered significant when p<0.05%. Results: Among the participating pharmacists, 56 (8.89%) and 216 (34.28%), respectively, stated that they rarely or never orient the customer regarding the disposal of unused and expired household medications, while 199 (31.59%) and 159 (25.24%), respectively, indicated that they almost always or always provide guidance. The frequency with which they provided guidance was influenced by the number of years since graduation (p=0.0047), the time they had worked in pharmacies and drugstores (p=0.0007), and whether or not they had a graduate degree (p=0.0181). Regarding the disposal of medications, among the 643 responses provided by the pharmacists, 516 (80.25%) indicated that they oriented customers to return them to a pharmacy. Conclusion: A small number of pharmacists always orient customers on the proper disposal that should be followed for unused and expired household medications, prioritizing their return to a pharmacy. In general, these pharmacists have longer periods of work experience and higher academic qualifications. Thus, it is important to increase knowledge through professional training and further education programs.

This study aimed to highlight the importance of health education for the control of VL (Visceral Leishmaniasis). They used the platforms Google Scholar, Scientific Electronic Library Online (SciELO), Virtual Health Library (VHL), and studies distributed in the databases PubMed and Capes Journals with the keywords: Visceral Leishmaniasis, Health Education, Public Health and Vectors, in addition to free terms related to the objective, such as environmental education and sandflies. The inclusion criteria were language (Portuguese and English) and availability (full text). The bibliographic references contained in the works found were also used in this review, as well as the official publications of the Brazilian government, such as the Manual of Surveillance and Control of visceral leishmaniasis. It is concluded that a large part of the population does not know the vector, proliferation, and methods of control of VL, for this reason, implementing educational actions of health education is essential to increase the level of knowledge through information related to the disease, and thus also reduce other diseases of similar epidemiological characteristics.
