Bottom Line: The availability of free medication samples in dermatology offices appears to change prescribing practices for acne, a common condition for which free samples are often available.
Author: Michael P. Hurley, M.S., and colleagues from the Stanford University School of Medicine, California.
Background: Free drug samples provided by pharmaceutical companies are widely available in dermatology practices.
How the Study Was Conducted: The authors investigated prescribing practices for acne vulgaris and rosacea. Data for the study were obtained from a nationally representative sample of dermatologists in the National Disease and Therapeutic Index (NDTI), a survey of office-based U.S. physicians, and from an academic medical center where free drug samples were not available.
Results: Branded and branded generic drugs (products that have novel dosage forms of off-patent products or use a trade name for a molecule that is off patent) accounted for 79 percent of the prescriptions written nationally by dermatologists compared with 17 percent at an academic medical center without samples. The average total retail cost of prescriptions at an office visit for acne was estimated to be twice as high ($465) nationally compared with about $200 at an academic medical center without samples.
Discussion: “Free drug samples can alter the prescribing habits of physicians away from the use of less expensive generic medications. The benefits of free samples in dermatology must be weighed against potential negative effects on prescribing behavior and prescription costs.”

Editorial: Drug Samples in Dermatology
In a related editorial, Kenneth A. Katz, M.D., M.Sc., of the Permanente Medical Group Inc., Pleasanton, Calif., and colleagues write: “The study was cross-sectional and did not determine causality, and no clinical outcomes were assessed. But the demonstrated association between samples and prescribing is strong and is consistent with a growing body of evidence that drug samples affect physician prescribing practices.”
“Hurley et al conclude their article by calling for policies to ‘properly mitigate’ the ‘inappropriate influence on prescribing patterns.’ We agree, and furthermore call on our own profession’s leaders to help dermatologists recognize the lack of evidence of benefit from samples and the substantial evidence of harm to patients and the health care system,” they continue.
“Our specialty should take a strong, united stance discouraging physicians from dispensing free drug samples in any form, including topical medications,” they conclude.
