Abstract

The aim of this study is to evaluate the frequency of dosing topical antibiotics as monotherapy in the treatment of acne vulgaris, and physician specialty prescribing these medications.This study is a retrospective review of all visits with a sole diagnosis of acne vulgaris (ICD-9-CM code 706.1) found on the National Ambulatory Medical Care Survey (NAMCS) in 1993-2010. We recorded the number of visits surveyed where acne vulgaris was the sole diagnosis, number of visits where topical antibiotics were the only treatment prescribed, and the specialty of physician in each encounter.Topical erythromycin or clindamycin were the sole medication prescribed in 0.81% of the visits recorded, with 60% of these prescriptions arising from dermatologists and 40% from non-dermatologists. The trend of prescribing topical antibiotic monotherapy is declining (p < 0.001) over the 18-year study period.The development of resistance of Propionibacterium acnes to topical antibiotic regimens has led to the need to re-evaluate the use of topical antibiotics in the treatment of acne vulgaris. While the rate of topical antibiotic monotherapy is declining, their use should be reserved for situations where the direct need for antibiotics arises. If a clinician feels that antibiotics are a necessary component to acne therapy, they should be used as part of a combination regimen.
