Fourth recall: Chantix from Pfizer for a carcinogenic ingredient
And now it’s four times for Pfizer – the Chantix recall, that is.
On Thursday, September 16, Pfizer extended its recall of Chantix 0.5 mg and 1 mg tablets to all lots. In July and August, Pfizer had already issued recalls of several batches of popular anti-smoking drugs because they may contain too much of the carcinogenic N-nitroso-varenicline that meets or exceeds the Food and Drug Administration’s acceptable intake limit. United States.
Pfizer’s latest expanded recall is intended as a precautionary measure, the company said.
Reason for recall
“Long-term ingestion of N-nitroso-varenicline may be associated with a potential theoretical increased risk of cancer in humans, but there is no immediate risk for patients taking this drug. The health benefits of quitting smoking outweigh the theoretical potential cancer risk from the nitrosamine impurity in varenicline, ”Pfizer said in its recall notice, posted on the FDA website.
According to the FDA, nitrosamines are common in water and foods, including cured and grilled meats, dairy products, and vegetables. “Everyone is exposed to some level of nitrosamines. These impurities can increase the risk of cancer if people are exposed to them at levels above acceptable levels over long periods of time. “
Chantix is designed to help people quit smoking, but it is intended for short term use. People who smoke cigarettes are 15 to 30 times more likely to have lung cancer than people who don’t smoke, according to the Centers for Disease Control and Prevention.
According to the FDA, there is no immediate risk to patients who take Chantix. But they should let their health care provider know to see if any alternative treatments are available.
Or, well, quit the cold turkey if you can.
