Pfizer voluntary re-called its smoking cessation drug Chantix because it contains a chemical that may cause cancer. The company says the possible substance was detected in 12 lots at levels above the company’s established acceptable daily intake.
It says long-term ingestion may be associated with a 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.
