Recalls
In 2018, the US Food and Drug Administration (FDA) reported that some versions of the angiotensin II receptor blocker medicines (including valsartan, losartan, irbesartan and other "-sartan" drugs) contain nitrosamine impurities. Health Canada also reported nitrosamine impurities.
The FDA issued revised guidelines about nitrosamine impurities in September 2024.
