The French pharmaceutical giant Sanofi announced Friday it has recalled in the United States and Canada of an over-the-counter drug, Zantac, used against heartburn. "As a precaution, Sanofi will proceed to the voluntary withdrawal of Zantac," said the French group in a statement.
"This withdrawal follows a possible contamination by an impurity of nitrosamine called N-nitrosodimethylamine (NDMA)", a substance classified as probable carcinogen by the World Health Organization, said the same source.
This is a report from the Canadian and American health authorities last month that established that "some drugs containing ranitidine (an H2 antihistamine, Ed), including Zantac, may contain low concentrations of NDMA," details Sanofi, which specifies that "evaluations are in progress" and that it "will continue to transmit the results of ongoing analyzes to the authorities".
In the United States, several large pharmacy chains like CVS and Walgreens have been removing the Zantac from their stores for several weeks.
