The FDA is encouraging physicians and other professionals to report suspected violations they encounter at medical conferences, in professional and lay media, in materials they receive, at company-sponsored presentations, and during sales-representatives' visits. Complaints can be submitted, with supporting materials or other evidence, to the agency by e-mail at badad@fda.gov, telephone at (877) RX-DDMAC, or mail. The reports can be submitted anonymously, but the agency recommends that those filing a complaint provide their name and contact information for follow-up and collection of additional materials.
