Chantix is an anti-smoking medication that was recalled in July 2021 after tests by Pfizer found a cancer-causing chemical impurity.
UPDATE: Pfizer Expands Chantix Recalls
In August 2021, Pfizer expanded a recall for the anti-smoking drug Chantix to include another 4 lots that contain high levels of cancer-causing impurities called nitrosamines. In total, Pfizer has recalled 16 lots of Chantix that were distributed to wholesalers in the U.S. and Puerto Rico between June 2019 and June 2021.
Chantix Recalled for Cancer Risk
July 19, 2021 — The FDA and Pfizer have announced a recall for 12 lots of the anti-smoking medication Chantix® due to a risk of cancer.
What is the Problem?
The recalled lots of Chantix® tested positive for N-nitroso-varenicline, which is a type of chemical called a “nitrosamine” that is believed to cause cancer in humans. Pfizer did not report any injuries due to the recalled Chantix medications as of July 2021.
What is the Risk?
People who take the recalled medications could face a potential risk of cancer, according to Pfizer: “Long-term ingestion of N-nitroso-varenicline may be associated with a theoretical potential increased cancer risk in humans, but there is no immediate risk to patients taking this medication.”
