Chantix Anti-Smoking Drug Contaminated with Nitrosamine Complaint

November 12, 2021

Pfizer, Inc. makes Chantix, an anti-smoking drug that contains an ingredient known as varenicline. However, the complaint for this class action alleges that the drug also contains “dangerously high levels of N-nitroso-varenicline, a carcinogenic impurity.” Although the drug has been recalled, the complaint alleges, Pfizer should have known about the impurity earlier, because of earlier warnings about nitrosamine contamination.
