Last week, the Food and Drug Administration (FDA) requested that manufacturers immediately withdraw all prescription and over-the-counter ranitidine products from the market, due to a possible contaminant. Ranitidine products, commonly known by the brand name Zantac, will not be available for new or existing prescriptions or over-the-counter use in the United States.
The request was made because the FDA has determined that the contaminant known as N-Nitrosodimethylamine in some ranitidine products increases over time and when stored at higher than room temperatures. This may result in consumer exposure to unacceptable levels of this impurity.
