Pfizer is recalling batches of its anti-smoking medication Chantix after an increased level of impurities that can cause cancer were found in the drug.
Included in the nationwide recall are two lots of Chantix 0.5mg Tablets, two lots of Chantix 1 mg Tablets, and eight lots of a Chantix kit of 0.5mg/1 mg Tablets, the drug manufacturer announced on Friday.
All are “due to the presence of a nitrosamine, N-nitroso-varenicline, above the Pfizer established Acceptable Daily Intake (ADI) level,” the company said in its recall announcement.
“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,” they added. “The health benefits of stopping smoking outweigh the theoretical potential cancer risk from the nitrosamine impurity in varenicline.”
