FTC and NYAG attack dubious Zika-related promotions. The FTC staff has sent warning letters to ten online marketers selling products that purportedly provide protection from the Zika virus. [FTC sends warning letters to online sellers making Zika virus-protection claims. FTC News release, Aug 5, 2016] The letters warn the recipients that Zika protection claims must be supported by competent and reliable scientific evidence in the form of well-controlled human clinical testing. The products of concern include wristbands, patches, and stickers that purportedly can repel the mosquitoes that carry Zika or otherwise protect users from the virus. The letters also point out that the testing supporting claims of protection from the Zika virus must use the mosquito species that are able to carry the virus—and must be able to demonstrate that the repellent effects last as long as advertised. On August 3, New York's Attorney General issued cease-and-desist letters to seven companies that market products with false claims that the products prevent or protect against Zika virus. The products included wrist bands, bracelets, patches and stickers impregnated with ingredients such as oil of geranium, cedar, lemon grass, soy, and citronella. A.G. Schneiderman issues cease and desist letters demanding companies Stop falsely advertising ineffective products as "Zika-preventive."

Heart Rhythm Case Reports, 2:248-249, 2016] Rivaroxaban is an anticoagulant drug that Janssen manufactures. The American Medical Association is urging lawyers to better regulate "fearmongering" commercials, and other commentators want the FDA empowered to regulate lawyer ads as it does drug company ads. [Rickard LA. How lawyers scare people out of taking their meds. Washington Post, Aug 5, 2016] The situation would be improved if the ads (a) warned that patients should not stop medications without medical advice and (b) by stating (when true) that risks are rare and benefits exceed risks.


City of Hope cancer ads criticized. Dr. William M. London has severely criticized the City of Hope for suggesting in ads that its care is "miraculous." He points out that although the facility provides excellent care, portraying it as miraculous is irresponsible and potentially dangerous. [London WM. Cancer miracle mongering by City of Hope.
