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.”
“Nitrosamines are common in water and foods, including cured and grilled meats, dairy products and vegetables,” the statement rationalized. “Everyone is exposed to some level of nitrosamines. These impurities may increase the risk of cancer if people are exposed to them above acceptable levels over long periods of time.”
On August 23, the FDA gave its theoretical ‘full approval’ to Pfizer-BioNTech’s Covid vaccine, which is being manufactured under a differerent label not currently on the market: Comirnaty.
“Biotech giant Pfizer expects to generate $33.5 billion in Covid-19 vaccine sales in 2021, up from previous estimates of $26 billion, according to its second quarter earnings reports,” Forbes reported in late July. “These projections are based on the 2.1 billion doses of the Pfizer/BioNTech vaccine which the company expects to manufacture and deliver by the end of the year.”
“Pfizer has repeatedly argued that a third dose will be needed, while many experts have said that more data is necessary to support the use of a booster shot,” the report noted. “Meanwhile, the World Health Organization has called for a moratorium on administering booster doses through 2021 to try to give low-income countries a chance to catch up on vaccination coverage.”
