The list includes products, which FDA testing show contain active drug ingredients which in the USA, are available only by prescription.
The 7 products are: Zimaxx, Libidus, Neophase, Nasutra, Vigor-25, Actra-Rx and 4Everon.
Chemical analyses showed the products contain either chemical ingredients that are similar to sildenafil or a second drug called vardenafil, the FDA said. The FDA has sent warning letters to the product marketers banning their products as illegal drugs.
The MayoClinic reports:
They contain potentially harmful drugs, the FDA says, which aren't included on the product labels. The drug-containing supplements aren't regulated or approved by the FDA, and because the source of the ingredients is unknown there's no guarantee that the ingredients are 'safe, effective or pure.'
The FDA says that products such as the ones on its warning list claim that they are 'all natural,' but they contain the active ingredients in FDA-approved medications for ED. An FDA chemical analysis showed that Zimaxx contains sildenafil, the active ingredient in the FDA-approved ED drug Viagra. The other products on the warning list contained either a version of sildenafil or vardenafil, which is the active ingredient in another FDA-approved ED drug, Levitra.
