Frequently Asked Questions About Erectile Dysfunction

Many TV commercials advertise ED medications, but what are they and how do they work? One of the most common is sildenafil (brand name Viagra), which is taken orally; other medications in this class include vardenafil (Levitra) and tadalafil (Cialis). Dr. Garza explains that medications in this class relax certain muscles in the penis, allowing for better blood flow. These pills need to be taken about an hour before sexual intercouse. Injections for more instantaneous erections are also available. Men may choose a self-injection option, an insert or testosterone replacement therapy.
