On October 6, 2026, the U.S. Food and Drug Administration published a warning letter, dated October 1 and addressed to Amazon CEO Andy Jassy, saying the retailer had sold unapproved over-the-counter treatments for genital herpes. The FDA says it has not approved "any over-the-counter (OTC) drug product for the treatment, cure, mitigation, or prevention of any STI." It called the sales a "serious public health concern." Agency staff bought the products through Amazon in July 2026 and confirmed they had been shipped through Fulfillment by Amazon.

Why It Matters

This is a clear example of the FDA's view that **a marketplace can be liable for what it fulfils**. The FDA has used FBA reasoning against Amazon before, but STIs are a particularly exposed category: there is real stigma, buyers want to avoid a clinic visit, and listings promise discreet cures. Sexual-wellness brands that sell on Amazon and Walmart Marketplace should expect stricter category gating and more listing takedowns that hit legitimate products. Lubricants, pH washes and "intimate care" topicals are exactly the products whose claims could look like disease treatment to an automated filter. For legitimate operators it is also an opening. Prescription herpes antivirals already reach patients through sexual-health telehealth, because they need a clinician. FDA pressure on the OTC gray market pushes that demand toward diagnosed, prescribed care, and toward at-home STI testing, which is the step the gray market skips. The broader lesson for anyone writing claims on intimate-care packaging is that wording like "relief" or "soothing" near an STI keyword now invites a warning letter.

The products named include FemiClear, HClear for him, HerpCare Ointment, HerpCare Spray, Herstat GST, Genital Herpes Ointment, RoyceDerm Herpes Relief Cream, Terragen HG Formula and Genital Herpes Intimate Wash. ICLG counts nine herpes-related products in the letter, while PhillyVoice reports that the FDA identified 10 unapproved new drugs. Some, including Terragen HG Formula, were labelled homeopathic. The FDA said that doesn't exempt them: homeopathic remedies face the same statutory requirements as any other drug. "Individuals who rely on these products may forgo timely, appropriate medical care, increasing their risk of severe complications such as infertility, sepsis, and death," the letter says. It adds that a false sense of being treated could lead people to pass infections to partners.

Amazon has 15 business days to explain how it will correct the violations and prevent them from happening again. The action was not limited to Amazon. Trade publication HBW Insight reports that the FDA warned 10 firms in total, including Walmart, over STI-treatment claims on OTC topicals, homeopathics among them. Law360 also describes the action as targeting 10 retailers. Herpes Cure Advocacy founder Dr. Jeffrey Klausner told MedPage Today that "the public should not be subject to these quack medicines."
