Tadalafil (Cialis®) is a medicine prescribed to men who are suffering from impotence. Tadalafil (Cialis®) must be taken prior to a man participating in sexual activity to have the desired effects. It works by promoting a greater flow of blood into a man’s penis while he is being aroused. This erectile dysfunction medication enables his penis to become erect and then sustains the erection for a longer period of time allowing him to complete the act of sexual intercourse.
