The Swedish Medical Products Agency (“MPA”; Läkemedelsverket) recently announced that it has launched a new guide (Ämnesguiden) that lists some substances and whether the MPA typically considers said substances to be medical or not. The purpose of this guide is to facilitate for the questioner, generally being a company, an authority or a consumer, to assess whether a certain substance included in a product is typically considered a medical substance – and the product thereby being subject to medical products regulation – or a foodstuff. The guide provides an indication on how the MPA has previously assessed certain substances. However, the guide is not legally binding and an overall assessment on a case-by-case basis must still be undertaken.
