Overall, there’s no “best” erectile dysfunction medication for everyone. You’ll usually get the best results by working with your healthcare provider to choose the medication that’s best suited to your needs and preferences.

- Avoid alcohol to enhance safety and effectiveness.
- Combined use may cause lightheadedness or dizziness.
Levitra, which contains vardenafil, and Viagra, which contains sildenafil, both belong to a class of medications referred to as PDE5 inhibitors. As their name suggests, PDE5 inhibitors work by inhibiting the effects of the PDE5 enzyme, or phosphodiesterase-5. This enzyme is found in the smooth muscle cells of your blood vessels, where it’s involved in regulating blood flow. Healthy erections are all about steady, consistent blood flow. When you feel sexually aroused, your nervous system causes the muscles in your penis to relax, increasing the flow of blood to the corpora cavernosa -- a pair of sponge-like chambers of tissue inside your penis. This process usually begins in response to sexual stimulation, such as being touched by your partner or seeing sexual imagery. As more blood flows to the corpora cavernosa, your penis becomes larger and firmer, creating an erection.

A fibrous membrane called the tunica albuginea wraps around this tissue, helping you to maintain your erection during sexual intercourse. After you reach orgasm and ejaculate, blood flows out from this tissue and your penis starts to become flaccid once again. A range of issues can cause erectile dysfunction, but many cases of ED are caused by health issues that affect blood flow to your penis.
