Zantac (Ranitidine)

Thousands of lawsuits have been filed against the manufacturers of Zantac, including Sanofi and GlaxoSmithKline, alleging that long-term use of the drug led to various cancers such as stomach, bladder, and kidney cancer. The plaintiffs argue that the companies failed to warn consumers about the risks associated with NDMA, a probable carcinogen found in Zantac. The litigation has led to massive recalls and regulatory scrutiny. Many cases have been consolidated into multi-district litigation (MDL) to streamline the legal process, and settlements and trials are ongoing as evidence continues to emerge about the extent of the health risks and the companies' knowledge of these dangers.
