The FDA is warning consumers that several products promoted and sold for sexual enhancement have been found to contain undeclared ingredients and should not be purchased or used.
Laboratory analysis has confirmed the presence of these undeclared ingredients in the following products:
- 3 Hard Knights (sildenafil, thiosildenafil)
- Dick’s Hard Up (tadalafil)
- Eyeful (hydroxythiohomosildenafil)
- Full Throttle On Demand (propoxyphenyl sildenafil)
- GoldReallas (sildenafil, thiosildenafil)
- Liu Bian Li (sildenafil)
Tadalafil, the active ingredient in the FDA approved prescription drug Cialis (Eli Lilly) and sildenafil, the active ingredient in the FDA approved prescription drug Viagra (Pfizer), are indicated for the treatment of erectile dysfunction (ED). Thiosildenafil and hydroxythiohomosildenafil are structurally similar to the active ingredient in Viagra and and propoxyphenyl sildenafil is structurally similar to the active ingredient in Cialis. These drugs may interact with nitrates found in some prescription drugs such as nitroglycerin and may lower blood pressure to dangerous levels. Nitrates are often prescribed to men to treat diabetes, high blood pressure, high cholesterol, or heart disease.
These products are sold nationwide through various distribution channels, including the internet and retail stores. The FDA recommends consumers to discontinue and discard these supplements immediately.
