Handling of unused prescription drugs - knowledge, behaviour and attitude among Swedish people

Unused prescription drugs can pose a security risk particularly for children or addicts; and they can pose an environmental risk if they are not disposed of properly through correct destruction. The general recommendation in Sweden is to return the unused medicines to a pharmacy. The Swedish Association of the Pharmaceutical Industry AB (LIF) has together with the Swedish retail chain Apoteket AB conducted surveys in 2001, 2004 and 2007 to investigate the level of knowledge in the general public on this issue. The result from the survey in 2007 shows, inter alia: 85% knew that correct disposal was to return unused medicines to a pharmacy and 43% had in fact returned their medicines to a pharmacy during the last 12 months. Of those who saved their medicines, 55% implied they would in the future return it to a pharmacy. 50% answered that they returned the unused medicines for environmental reasons and 42% answered that they worry about the environmental impact of medicines. Comparing the results from the earlier surveys it can be concluded that an increasing number of the Swedish population does return unused medicines to a pharmacy for correct disposal. Environmental concerns are getting more important than security concerns as a reason for returning unused medicines to a pharmacy and a growing fraction is worried about the environmental impact of pharmaceuticals.
