Pfizer Chantix Contaminated with NDMA Complaint

October 12, 2021

Pfizer makes the drug Chantix to help people stop smoking. The complaint refers to Chantix as a VCD, or varenicline-containing drug. But the complaint for this class action alleges that the company has been putting out adulterated or misbranded Chantix that has been contaminated with “a probable human carcinogen known as n-nitroso-varenicline.” The complaint alleges that Pfizer had been warned about this possibility and “was on notice of other potential nitrosamines as well, such as n-nitrosdimethylamine (‘NDMA’) and n-nitrosodiethlamine (‘NDEA’).”
