Side-by-side evaluation of alternate options with other options
Other commonly used PDE5 inhibitors for ED include sildenafil, vardenafil and avanafil. Non-oral options such as alprostadil are available for people who cannot use PDE5 inhibitors.

- Vardenafil (Levitra): similar onset and duration to sildenafil with a different side effect profile for some users.
- Avanafil aka Spedra: may have a faster onset in some people, sometimes working in 15 to 30 minutes, with several hours of effect.
- Alprostadil: available as an injection or urethral suppository for patients unsuitable for oral PDE5 inhibitors.

Choice should be based on individual tolerability, response, underlying health conditions and cost. Discuss treatment options in concert with your clinician.
