Valsartan was not entirely taken off the market, but certain batches were recalled starting in 2018 due to contamination with nitrosamines, specifically N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA), which are potential carcinogens. The presence of these impurities was linked to changes in the manufacturing process by some suppliers. Regulatory agencies like the FDA and EMA initiated recalls to ensure patient safety, while valsartan from uncontaminated sources remained available.
