FDA says Pfizer has recalled four additional lots (to a total of 16) of its Chantix (varenicline) due to the presence of N-nitroso-varenicline above the company’s acceptable limit for the impurity. An online [notice](https://www.fda.gov/drugs/drug-safety-and-availability/fda-updates-and-press-announcements-nitrosamine-varenicline-chantix?ref=fdaweb.com) says the agency reminds consumers taking recalled Chantix to continue taking their current medicine until their pharmacist provides a replacement or their doctor prescribes a different medication that treats the same condition. “The health benefits of stopping smoking outweigh the cancer risk from the nitrosamine impurity in varenicline,” FDA says.
