[11-30-2018] The Food and Drug Administration is advising consumers not to purchase or use Willy Go Wild, a product promoted and sold for sexual enhancement on various websites and in some retail stores.
FDA laboratory analysis confirmed that Willy Go Wild contains sildenafil and tadalafil, the active ingredients in the FDA-approved prescription drugs Viagra and Cialis, respectively, used to treat erectile dysfunction. These undeclared ingredients may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower blood pressure to dangerous levels. People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.
Health care professionals and patients should report adverse events or side effects related to the use of this product to FDA's MedWatch Safety Information and Adverse Event Reporting Program:

Consumers should exercise caution before purchasing any product in the above categories.
