Storage and disposal of pharmaceuticals at home: a systematic review.

This study's objective was to analyze Brazilian and international scientific evidence on the reasons people store medication at home and the disposal methods used. This systematic literature review includes studies published from 2001 to 2016 and indexed in PubMed, Lilacs and Elsevier's Scopus Database, using the following key words: Disposal of medicines in household, Disposal of drugs expired, Residential expired drugs, Management of expired medications in household. Thirty-three studies were selected after applying inclusion and exclusion criteria. The studies reveal that the main reasons people keep a stock of medicines at home include the possibility of future use, leftovers from previous treatments, and self-medication. Inappropriate disposal methods prevail, such as throwing medicines in the household trash or flushing them into the sewer. Some countries have adopted programs to educate on proper storage and disposal of medicines, though only one study describes a national program guiding these practices that is free of charge. Evidence shows there is a need to implement public policies intended to provide guidance on the proper storage and disposal of medicines at home.
