| The United States: Public Notification: 3 Hard Knights Contains Undeclared Drug Substance Sildenafil and Thiosildenafil |
| |
The Food and Drug Administration (FDA) is advising consumers not to purchase or use 3 Hard Knights, a product promoted and sold for sexual enhancement on various websites and in some retail stores. FDA laboratory analysis confirmed that 3 Hard Knights contains sildenafil and thiosildenafil. Sildenafil is the active ingredient in the FDA approved prescription drug Viagra, used to treat erectile dysfunction (ED). Thiosildenafil is a substance structurally similar to sildenafil. These undeclared ingredients may interact with nitrates found in some prescription drugs such as nitroglycerin and may lower blood pressure to dangerous levels. Men with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. Consumers should stop using this product immediately and consult a health care professional as soon as possible if you have experienced any negative side effects.
