We prescribe Tadalafil (generic Cialis®)* and Sildenafil Citrate (generic Viagra®)**, which are FDA-approved and clinically proven to treat erectile dysfunction. Tadalafil* is a generic form of Cialis®, an oral medication FDA-approved for treating Erectile Dysfunction. Tadalafil (generic Cialis®)* works by blocking PDE5 (phosphodiesterase type 5), an enzyme in the body that breaks down chemicals responsible for blood flow (and therefore erections). The result is increased blood flow to the penis to help a man get and keep an erection. Tadalafil (generic Cialis®)* can be taken daily or as-needed. For daily use, take one tablet once per day without regard to timing of sexual activity. For as-needed use, take Tadalafil (generic Cialis®)* at least 1 hour before sexual activity and up to 4 hours before.
