The red warning triangle is a part of additional information on labelling required nationally for Iceland (blue box). Medicinal products which can reduce the ability to drive or operate machines must have a warning triangle. This once harmonised requirement among the Nordic countries has changed in recent years. The red warning triangle is applicable In Denmark, Norway and Finland. Denmark and Norway publish lists of active substances that shall bear the warning triangle on packaging but their contents differ. This symbol is no longer used in Sweden. These different requirements between the Nordic countries have created challenges for Iceland. Being a very small market, products are often in multilingual packaging, most often shared with one of the Nordic countries. The consequence is that products that are on the market in Iceland and can reduce the ability to drive or operate machines are not all bearing the warning triangle, it depends on which of the Nordic countries Iceland shares packaging with. Information on ability to drive or operate machines are always stated in the packaging leaflet of each product. Therefore it is of vital importance to read the packaging leaflet.
