1. Pills Viagra, Cialis (tadalafil), and Levitra (vardenafil) fight erectile dysfunction by relaxing smooth muscle in the penis, a process that increases blood flow and enables an erection.

2. Injections If oral medications don’t work, a doctor might recommend injecting medication directly into the base or the side of the penis with a tiny needle or inserting a suppository into the urethra.

3. Suppositories For guys who prefer not to inject themselves or have a fear of needles, a suppository called MUSE—containing the drug alprostadil—is also available but it is not considered as effective as the shots. “The injection is a direct delivery of medication to the penis, while the suppository is inserted into the urethra and when it is absorbed, it loses some of its strength,” says Ridwan Shabsigh, MD, director of the division of urology at Maimonides Medical Center and professor of clinical urology at Columbia University in New York City.
