Zantac and generic heartburn drugs pulled off some store shelves because of cancer worries
CVS Pharmacy has stopped selling Zantac, as well as its generic version of the heartburn medication, over concerns that they might contain a substance that could cause cancer. CVS, the largest pharmacy chain in the country, said over the weekend it was suspending sale of Zantac and other products which contain ranitidine until further notice. The US Food and Drug Administration said earlier this month that it has learned that some ranitidine -- acid-reducing and heartburn medicines, including those known by the brand name Zantac -- contain low levels of an impurity that could cause cancer.
