A 33-year-old man has been arrested for selling an unregistered product claiming to treat sexual dysfunction. The product was found to contain undeclared Western drug ingredients sildenafil and tadalafil.

He sold the product named Vegetal Vigra on the Internet and three boxes of it was seized from him. Thirteen boxes of it and four boxes of two slimming products were also found in his home.

The unregistered product was reportedly obtained from the Mainland. The Department of Health will examine the products.

Sildenafil and tadalafil are Western medicines usually used for treating male sexual dysfunction. Their side effects include low blood pressure, headache, vomiting, dizziness, and transient vision disturbances. They can interact with nitrates found in some prescription drugs and lower blood pressure to dangerous levels. Their improper use can pose serious health risks, especially for people with heart problems.
