Trends in varenicline use for tobacco cessation, and their implications.

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 (brand) varenicline (name) 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 ≥18 years of age 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 years 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 prerecall 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use; these include the requirement for a prescription and the black-box warning by the Food and Drug Administration, rescinded in 2016.
