Pfizer Halts Production of Anti-Smoking Drug Chantix Over Cancer Concerns

Pfizer Halts Production of Anti-Smoking Drug Chantix Over Cancer Concerns
Calendar icon September 30, 2021

Pharmaceutical giant Pfizer moved from pausing production to halting the manufacture of their popular anti-smoking drug, Chantix following finding the drug contains high levels of the “probable human carcinogen” nitrosamine.  The voluntary recall of all lots of .5 mg and 1 mg Chantix (varenicline) was issued together with the recommendation that patients consult their health care providers.

Nitrosamine in significant levels was found in Chantix.  Nitrosamine has been determined to be a carcinogen (cancer-causing) in animal testing and is classified as a probable human carcinogen by the World Health Organization.  This year the FDA updated its pharmaceutical manufacturing standards “to reduce and mitigate nitrosamine impurities in active pharmaceutical ingredients and drug products.”

The FDA has identified multiple potential sources of nitrosamine in pharmaceutical products including manufacturer use of impure products, cross-contamination, and a lack of quality control and emphasizes that “manufacturers of … drug products should take appropriate measures to prevent unacceptable levels of nitrosamine impurities in their products.”

Pfizer originally paused the distribution of the drug in June, citing “an abundance of caution and further testing.” Although the company states that there is no immediate risk to patients taking Chantix, they have advised patients to consult with their health care providers for alternative treatments or medications. Distributors and wholesalers have been asked to stop the use and distribution of the tablets over the concerns.

The FDA had initially approved Chantix in May of 2006 as a prescription medication to help adults over the age of 18 to quit smoking and is typically used for 12-24 weeks. Noting Pfizer’s recall, the FDA states that “there is no immediate risk to people currently taking the drug” and that the “benefits of quitting smoking still outweigh any cancer risk from Chantix.”

If you have taken the prescription drug Chantix and have developed cancer after long-term use, you may be entitled to compensation.

  • Cellino Law and more specifically my attorney, Gregory V. Pajak, Managing Attorney, and as a whole the Cellino Law Firm and its organization. This is by far one of the most professional law firms and attorney I have ever engaged with and retained in my 35 years. The level of professionalism goes beyond words, the care and constant engagement with me as the client was touching. I was never ever just treated as simply a CASE with potentially a significant dollar number attached to my file. I was engaged regularly, Tracey (Ass’t) and Greg always made sure to remain constant, as well as consistent in overseeing that my case was handled properly and that it did matter in many ways - ensuring that the end result(s) would be fair and reasonable to my case/injury. The regular follow-up calls were very satisfying, knowing that you’re involved in your case matters significantly AND always. One of my main items to recognize Cellino Law and Gregory is that whenever I called, I was able to get through to speak directly to my Lawyer and he would answer any if not all of my questions in a very professional and genuinely caring manner. I always felt cared for and protected legally and more importantly, I was made feel as a human being that was being cared for and always keeping me abreast of all matters connected to the case. There was never a point I felt let down, on the contrary -the level of service was “STELLAR”. Greg is the consummate professional, a ‘role model’, if you will, for what other attorneys should strive to become when dealing with their clients.

  • I am writing to let you know what an outstanding job George Gridelli did for me in my personal injury lawsuit. His professionalism and expertise were evident at our first metting and he and his paralegal Diane D'Andrea took care of me as if I was a friend and not merely a client. They both went above and beyond for me in so many ways that it would be too numerous to list and I am grateful to have had such an exemplary team represent me. When working with George and watching him in court he personified to me what a lawyer is supposed to be - an honest, extremely compentent man who helped guide me through the legal system. I could not have obtained better representation anywhere else at any price. To me that says a lot abut you and your firm's integrity. Thank you again for representing me and for having such stellar individuals working for you! I will continue to recommend your firm.

  • I am writing this letter to say how much I appreciate your services pertaining to my case. Your injury attorney took a hands-on approach and left me fully informed at all times as to where my case was going as well as how much ground we had to cover; leaving the final decisions in my hands but making sure that I knew all of the risks involved in the choices. I have dealt with a few law firms in my life on various different cases and this is the first time that I never had to call and/or track down my lawyer… because of this, I have and will continue to recommend Cellino Law to my friends and associates.
