Several sexual enhancement supplements were recalled this week because the products contain undeclared drugs, according to the Food and Drug Administration.
The products, called Vicerex and Black Ant, manufactured by American Lifestyle, are marketed as enhancing sexual desire and performance.
Vicerex was found to contain the drug tadalafil (sold under the brand name Cialis), and Black Ant was found to contain the drug sildenafil (brand name Viagra). Both tadalafil and sildenafil are FDA-approved drugs to treat erectile dysfunction.
