A Florida man is suing Zantac maker Sanofi Aventis US LLC over claims that his long-time use of the heartburn drug caused him to develop breast cancer, Law360 reported.

Joseph L. Galimidi, said that he started using Zantac in 2009, and continued using it for the next nine years to treat heartburn and acid reflux. He was diagnosed in 2013 with breast cancer, had a mastectomy, and started chemotherapy. He says he has suffered lifelong injuries from his cancer.

Galimidi connected his Zantac use to his cancer diagnosis after learning last fall that several products containing ranitidine, the same active ingredient in Zantac, contained levels of the probable cancer-causing impurity N-Nitrosodimethylamine, or NDMA, far above what the Food and Drug Administration (FDA) deems safe for daily consumption.

On April 1, more than six months after Galimidi filed his lawsuit, the FDA called for the withdrawal of all prescription and over-the-counter drugs containing ranitidine, including Zantac, after finding that levels of NDMA in ranitidine can increase when exposed to higher temperatures and the longer the length of time since it was manufactured.

Laboratory animals exposed to NDMA have developed cancerous tumors and liver damage. There have been no studies published at this point that identify a person’s risk of developing cancer who has taken these drugs. But, the impurity may be attributed to several different types of cancers, including liver, bladder, stomach, colon, kidney, and pancreatic cancer.

Galimidi claims that Sanofi knew or should have known that Zantac contained NDMA. He is one of several people who have filed lawsuits against makers of Zantac.
