[Can environmental impact be considered as a dimension of the proper use of medicines? From the 5th Forum of the Association for the Proper Use of Medicines]

Through their footprint throughout their life cycle, from production to use, medicines have a significant impact on the environment. Reducing this impact is rarely considered from the perspective of the choices that healthcare professionals might have to make when prescribing or dispensing medicines. Should we consider environmental impact, alongside effectiveness and tolerance, one of the dimensions of the proper use of medicines? To address this question, the 5th Forum of the Association for the Proper Use of Medicines highlighted the main sources of pharmaceutical pollution: the carbon footprint linked to production, greenhouse gas emissions, the impact of residues on water and waste from packaging. While the eco-design of medicines should make it possible to limit their environmental impact upstream, there are still few initiatives aimed at their use. The Swedish "Hazard Score" assessment tool, which classifies compounds according to their potential to pollute the aquatic environment, was presented as a tool for guiding prescription choices. Through the exchanges between the various stakeholders (public authorities, doctors, pharmacists, manufacturers, patients) during this forum, recommendations were drawn up both on scientific and ethical grounds.
