They state that the list of potential adverse effects now contains atrial fibrillation, alongside other side effects previously noted in product guidance. The coverage does not detail the number of reported cases or provide specific clinical evidence within the articles.

Overall, the reporting focuses on the change to the manufacturer’s or regulator’s published side-effect information for the Nicotinell mint lozenges, emphasizing that readers should be aware of the newly listed heart-related risk when using the product as directed.
