Background: Tobacco use remains a leading cause of death in the U.S. Varenicline is a preferred medication for tobacco cessation, and a prior report in the literature showed its use fell dramatically after the voluntary recall of Chantix (name-brand varenicline) in July 2021.
Objectives: Working with data on prescriptions for varenicline and nicotine-replacement therapy (NRT), we studied use from 2018 to 2023 to determine if varenicline use had recovered or if there had been a compensatory increase in NRT use.
Methods: Data are yearly from state employees and their dependents who were aged >18 years and were health-insurance beneficiaries of the Washington Public Employees Benefits Board from July 2018 through June 2023. Data include numbers of tobacco users and numbers of prescriptions filled.
Results: The 5-year prevalence of tobacco use among 224,816 beneficiaries was 4.6%. The percentage of tobacco users who filled a prescription for varenicline fell from highs of 9.5% and 9.6% in the 2018-2019 and 2019-2020 year to lows of 5.3% and 6.4% in the 2021-2022 and 2022-2023 years. For nicotine replacement therapy, prescriptions rose modestly over the 5 years, from 4.5% in 2018-2019 to 6.0% in 2022-2023.
Discussion: Varenicline use dropped after the voluntary recall of Chantix by Pfizer in mid-2021 and has not returned to pre-recall levels.
Conclusion: Pharmacists and other clinicians should address this drop, in addition to addressing longer-term challenges to increasing varenicline use; these include the requirement for a prescription and the black-box warning by the Food and Drug Administration, rescinded in 2016.
