Viruseptin Lozenges

Viruseptin is a brand of cold and flu relief products widely available in Northern Europe. The product shown consists of throat lozenges containing iota-carrageenan, a natural substance derived from red seaweed. This active ingredient forms a protective physical barrier against viruses on the throat mucosa.

The brand was originally developed and launched by the Austrian pharmaceutical company Marinomed Biotech AG, which holds the patents for the Carragelose technology used in the lozenges. While Marinomed is the company of origin and innovator, the brand is commercialized and distributed in the Swedish and Nordic markets through Karo Healthcare (formerly Karo Pharma). Production typically takes place in Austria, where the specialized manufacturing facilities for this specific medical technology are located.
