Pfizer, a leading pharmaceutical manufacturer that happens to produce the only ‘fully authorized’ Covid vaccine in the United States, is recalling a drug that has been FDA-approved for 15 years. Chantix, the anti-smoking drug, has been tied to cancer with long-term usage, and is therefore being voluntarily recalled.
“Pfizer is voluntarily recalling all lots of Chantix 0.5 mg and 1 mg Tablets to the patient (consumer/user) level due to the presence of a nitrosamine, N‑nitroso-varenicline, at or above the FDA interim acceptable intake limit,” the manufacturer said in a statement. “As alternative suppliers have been approved in the United States, Pfizer is undertaking this precautionary measure.”
“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 statement continued. “The health benefits of stopping smoking outweigh the theoretical potential cancer risk from the nitrosamine impurity in varenicline.”
