In November 2018, Sandoz Inc. voluntarily recalled tablets of losartan potassium co-formulated with hydrochlorothiazide. The recall affects one lot of losartan potassium – hydrochlorothiazide 100 mg/25 mg 1,000-count bottles distributed after October 8, 2018. One of the raw ingredients, losartan, USP, made by Zhejiang Huahai Pharmaceutical Co. contains the contaminant N-nitrosodiethylamine (NDEA). In December 2018, Torrent recalled 2 lots of losartan potassium 100 mg tablets. The raw ingredient, losartan, USP, made by Hetero Labs Limited, contains the contaminant NDEA. The International Agency for Research on Cancer classifies NDEA as a probable human carcinogen. It is found naturally occurring in certain foods, drinking water, air pollution, and industrial processes. No adverse events have been reported at this time.
