Pfizer Recalls All Chantix Nationwide

Earlier this summer, Pfizer halted global distribution of its smoking cessation drug, Chantix. A few weeks later, the company recalled over a dozen lots of the drug. Now, according to a Fierce Pharma article, the drugmaker is recalling all 0.5 mg and 1 mg lots across the country. The reason is the the drug was found to contain unacceptable levels of a specific nitrosamine, which can cause cancer over time with exposure to high levels. The drug was approved by the FDA 15 years ago, and saw nearly a billion in sales last year.
