Pfizer Chantix Adulterated with N-Nitroso-Varenicline Complaint

September 23, 2022

One of Pfizer, Inc.’s most popular products is the varenicline-containing drug (VCD) Chantix. Chantix is designed to help people stop smoking, and, unlike many other products for this use, it does not contain nicotine. However, the complaint for this class action alleges that the drugs have recently been contaminated with N-nitroso-varenicline, and possibly other substances as well. The complaint alleges this renders the drugs unfit for their intended use and worthless.
