Trends in Oral Antibiotic Use for Acne Treatment: A Retrospective, Population-Based Study in the United States, 2014 to 2016.

Abstract

Antibiotic resistance related to prolonged antibiotic use is an emerging threat to public health. To evaluate recent trends in oral antibiotic use for acne treatment. A retrospective study was conducted from January 2014 through September 2016 using the IBM MarketScan® claims database. Patients were aged ≥9 years, prescribed an oral antibiotic, and diagnosed with acne vulgaris on 2 separate occasions. The primary outcome was the duration of oral antibiotic treatment over 12 months; continuous use was defined as ≤30-day gap between prescriptions. The most commonly prescribed antibiotic treatments (N=46,267) were doxycycline (36.7%) and minocycline (36.5%). Overall, 36%, 18%, 10%, and 5% of patients continuously used any oral antibiotic at 3, 6, 9, and 12 months, respectively. Among patients who continuously used tetracyclines, a similar percentage was prescribed minocycline (40.2%, 18.6%, 10.5%, and 5.1%) vs doxycycline (34.7%, 14.6%, 7.7%, and 3.9%) at 3, 6, 9, and 12 months, respectively. A greater percentage of patients continued use of tetracyclineclass antibiotics than other therapeutic classes. Retrospective analysis of health-care claims data. Relatively short study duration. Nearly 20% of patients continuously used oral antibiotics for ≥6 months, exceeding American Academy of Dermatology guideline recommendations of 3 to 4 months.
