Background: Reverse logistics is made up of attitudes, processes and means to provide the return of medicines and their packaging to the business sector for an environmentally appropriate destination. The procedure is necessary to ensure the protection of the environment and public health. Objectives: The objective of the study was to define the spatial analysis of the reverse logistics of medicines in pharmacies in the state of Pará. Methods: This is a cross sectional study, and the research covered the medicines collected by a pharmacy chain in the period from 2020 to 2022. To obtain the data, the medicines were collected, weighed, segregated and the weight released on a dedicated waste management platform. All municipalities in the state of Pará subject to georeferencing were processed using the free software Geographic Information System. Of the 144 municipalities in the state of Pará, only 10 had records of reverse medication logistics. Results: A total of 3125.63 Kg of products were collected and the city of Belem was responsible for 92.5% of the collection.
