Armstrong K, Schwartz JS, Asch DA.
Direct sale of sildenafil (Viagra) to consumers over the Internet.
N Engl J Med 1999 Oct 28; 341:(18):1389-92


The authors conducted a systematic search of the World Wide Web to identify all sites that were selling sildenafil directly to consumers and analyzed information on the sites as to the geographic origin of the Web site, the cost of the service and the drug, and whether it provided information about sildenafil, requested information from consumers, provided disclaimers and warnings and required a medical consultation (review of information about medical history by a physician).
