The affected lots of Chantix are being pulled from the market after it was discovered that they may contain levels of N-nitroso-varenicline, a type of nitrosamine, that exceed the Acceptable Daily Intake (ADI) level set by 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,” the recall notice states, noting that Chantix is generally used in the short-term for smoking cessation to begin with. Pfizer explains that, at the time the recall notice was issued, there had been no adverse health outcomes associated with use of the recalled medications. In fact, the company says that smoking is more dangerous than the ingredient being called into question. “The health benefits of stopping smoking outweigh the theoretical potential cancer risk from the nitrosamine impurity in varenicline. Nitrosamines are common in water and foods, including cured and grilled meats, dairy products and vegetables. Everyone is exposed to some level of nitrosamines,” Pfizer said in its recall announcement. If you have any of the affected lots of Chantix at home, contact your doctor to decide on the course of action that’s best for you, whether that means getting a new package of the medication or changing your course of treatment. You should also contact Stericycle Inc. at 888-276-6166 (available on weekdays from 8 a.m. to 5 p.m.) for information on how to return the medication and get a refund.
