The news was also mischaracterized as it's not the active ingredient that is associated with cancer risk, it's a contaminant/by product of the production process, so it's more of a product safety recall than a drug safety recall. As far as I know, this was a voluntary risk-reduction recall by the manufacturer and not an FDA recommended or ordered recall based on safety data.
