The FDA is warning consumers to not buy or use Zhen Gong Fu, a product promoted for sexual enhancement.
An analysis confirmed that Zhen Gong Fu was found to contain undeclared sildenafil, the active ingredient in Viagra (Pfizer), indicated for erectile dysfunction (ED). Sildenafil may interact with nitrates found in some prescription medication such as nitroglycerin and may significantly lower blood pressure.
The FDA advises that consumers should stop using this product immediately and throw it away. Those who have experienced adverse effects should consult a healthcare professional as soon as possible. Zhen Gong Fu is sold on various websites and in some retail stores.
