The anti-smoking drug Chantix was recalled in July 2021 after tests found a cancer-causing chemical impurity.
UPDATE: Chantix Recalled Due to Risk of Cancer
In July 2021, Pfizer recalled 12 lots of Chantix due to high levels of nitrosamine chemicals, which are an impurity that is believed to cause cancer in people. According to the recall, “Long-term ingestion of N-nitroso-varenicline may be associated with a theoretical potential increased cancer risk in humans,” Pfizer warned.
Pfizer recalled the following lots of Chantix due to a risk of cancer:
- 56-count bottles of Chantix 0.5-mg tablets with Lot #00019213 and expiration date January 2022
- 56-count bottles of Chantix 0.5-mg tablets with Lot #EC6994 and expiration date May 2023

Pfizer also recalled 8 lots of Chantix cartons with one blister pack of 0.5 mg tablets and one blister pack of 1 mg tablets due to a risk of cancer.
