Provider Alert! Chantix (Varenicline) Tablets Voluntary Recall

Date: September 22, 2021

Attention: All Providers and Pharmacies

Effective Date: September 16, 2021

Providers should monitor the Texas Children’s Health Plan (TCHP) Provider Portal regularly for alerts and updates associated to the COVID-19 event.  TCHP reserves the right to update and/or change this information without prior notice due to the evolving nature of the COVID-19 event.

Call to action: Pfizer has issued a voluntary recall of all lots of CHANTIX (Varenicline) Tablets. Potentially impacted customers were notified with a recommendation to not stop taking their medication until discussing with their doctor.

The recall is due to discovery of an impurity (nitrosamine [N-nitroso-varenicline]) in the finished product. Nitrosamine is classified as a probable human carcinogen that may be found in water and foods, including cured and grilled meats, dairy products and vegetables. Pfizer has not received reports of adverse events related to this recall to date.

How this impacts providers: Members may reach out to providers upon receipt of a recall letter from their health plan and/or pharmacy. Pharmacies may dispense another manufacturer’s Chantix due to this recall.

Next steps for providers: Providers should stay vigilant about additional recalls related to Chantix.

Additional information about the recall can be found on the FDA website.
