Pfizer withdraws its Chantix drug:
Pfizer has expanded its Chantix quit smoking drug recall to include all 0.5mg and 1mg tablet batches due to a possible carcinogenic ingredient that may be present above the acceptable intake limit set by the Food and Drug Administration.
The drug Chantix may have the presence of N-nitroso-varenicline in FDA interim intake levels above acceptable, which has the potential for cancer risks with long-term use. The irony of a drug created to help quit a cancerous habit, smoking, which is itself carcinogenic.
Pfizer said there is no immediate risk to patients taking the drug and that the benefits of taking the drug outweigh the potential to cause cancer from the drug.
N-nitroso-varenicline or nitrosamines are commonly found in water and food, as well as cured and grilled meats, dairy and vegetables, and fried products. They are especially abundant in overcooked products. At high levels and for long periods of time, they can cause cancer.
Chantix, which is used to help people quit smoking, is intended for short-term use.
The recalled drug was distributed nationwide in the United States, the U.S. Virgin Islands, and Puerto Rico from May 2019 to September 2021.
Individuals who are currently taking the recalled Chantix should consult their physician regarding an alternative treatment option. Pfizer said in a statement on the recall: "Pfizer places the utmost emphasis on patient safety and product quality at every stage of the manufacturing process and supply chain."
The drug company said it has not received any reports of adverse events related to the recall. We could say fortunately, as it means that it was not yet on the market enough to cause any damage. At the same time, the danger of nitrosamines has long been known and it is surprising that a pharmaceutical powerhouse like Pfizer has fallen into such a trivial mistake.
