BackgroundLittle is known about how dermatologists prescribe hormonal antiandrogen acne treatment (HAAT).ObjectiveThe aim of this study was to investigate dermatologists’ HAAT-prescribing habits and HAAT’s impact on systemic antibiotic use in women with acne.MethodsWe performed a retrospective study at an academic medical center of female patients receiving HAAT (combined oral contraceptive [COC], spironolactone) for acne from January 2005 to October 2015. Data from a control group of female acne patients who never received HAAT were also collected.ResultsA total of 672 female patients received HAAT. Out of all systemic medications for acne, antibiotics were used as first-line treatment in 39% of patients, COCs in 12%, and spironolactone in 21%. Mean antibiotic durations in patients who initiated HAAT for the first time at the study site (250.4 days) were significantly longer than in patients who received HAAT prior to presentation and continued HAAT at the study site (192.0 days) (p = 0.021). A statistically significant inverse association was found between HAAT use and mean antibiotic duration (p = 0.016).ConclusionsHAAT is not typically used as a first-line systemic therapy in women with acne. HAAT usage is associated with shorter cumulative antibiotic durations and early HAAT initiation can decrease systemic antibiotic use in acne treatment.
