Sanofi US is concerned by the proliferation of products that may appear to be from pharmaceutical companies but in fact are fakes or counterfeits. Counterfeit drugs are designed to deceive consumers by using misleading packaging and mimicking the shape, color, size, and imprints of genuine drugs. Counterfeit drugs often contain only trace amounts of the alleged active ingredients and sometimes have no active ingredients at all.

Sanofi is committed to eradicating these illegal operations. Why? Because taking counterfeit medications can cost patients their lives. As a company, we are involved with many organizations, including international pharmaceutical associations and law enforcement agencies to address this ever-growing problem.
