Pfizer has voluntary recalled several lots of its anti-smoking drug, Chantix.
They contain presence of a nitrosamine chemical, N-nitroso-varenicline, that may cause cancer. Pfizer says the possible carcinogen was detected in 12 lots at levels above the company’s established acceptable daily intake.
The company says long-term ingestion of the chemical may be associated with potential increased cancer risk. However, Pfizer says the health benefits of stopping smoking outweigh the potential risk.
The FDA says people should continue taking the medicine until their pharmacist provides a replacement, or their doctor prescribes a different medication.
