Walmart stops sales of Zantac and related drugs over cancer fears

Walmart has become the latest store to halt sales of the popular heartburn treatment Zantac after health regulators warned about a potentially dangerous contaminant in the drug

The nation's largest retailer said Wednesday that it suspended sales of all drugs sold over the counter, or without a prescription, that include Zantac's active ingredient, ranitidine. Aside from Zantac, that includes Equate and Member's Mark brands.

The U.S. Food and Drug Administration said last month it detected low levels of a probable cancer-causing chemical in Zantac and related generic drugs to treat ulcers and reflux disease. The same chemical has been linked to dozens of recalls of prescription blood pressure drugs in the past year.

In large quantities, the FDA says chemicals found in the products are believed to cause cancer, but the amount found in Zantac is not much more than what can be found in common foods.

The drugstore chains CVS Health, Walgreens and Rite Aid have already pulled Zantac products from their shelves.

CVS says it will continue to sell other heartburn medicines like Pepcid and Tagamet along with their generic equivalents. Zantac is sold by Sanofi which is reportedly cooperating with the FDA as well as conducting its own investigations.

Sandoz, a unit of Switzerland-based pharmaceutical giant Novartis, halted the distribution of generic versions earlier this month.
