Warning Letter – Even FB Claims Are Regulated

An important lesson from a Warning Letter citing FB Claims:

In this Warning Letter to SilveryGuy, dated August 14, 2020, FDA – CDER informed the recipient that they had evaluated the company’s website and Facebook (FB) page. This demonstrates that even social media claims can establish the intended use of a product. Be careful what your company claims on Facebook!


The FDA found that the company’s Colloidal Silver was misleadingly represented as safe and/or effective for the treatment or prevention of COVID-19. Among other evidence, the FDA cited a particular Facebook post that said, “What’s your plan if the wuhan #Coronavirus fills up hospitals with patients and you can’t get a bed for treatment? #colloidalsilver may be your last option or your first. Check my latest blog entry to find out how you can save your life and keep your family safe.”
