Tadalafil is the main ingredient in Cialis, a drug approved for treating erectile dysfunction. Tadalafil is known to react with nitroglycerin and other nitrates, causing very serious health concerns such as extremely low blood pressure. For this reason, the Food and Drug Administration has warned against its use.
The product was also found to contain benzamidenafil, according to the FDA, an ingredient that has not been approved by the FDA. The manufacturers neglected to state that this was one of the active ingredients. Benzamidenafil, like tadalafil, has been proven to react with nitrates, and it drastically lowers blood pressure. This could prove to be life-threatening for people who take medication containing nitrates for conditions such as heart disease, diabetes, high blood pressure and high cholesterol.
