Other drugs are available that can treat erectile dysfunction (ED).

If you’re interested in finding an alternative to Viagra, talk with your doctor. They can tell you about other medications that may work well for you.

Examples of other drugs that may be used to treat ED include: tadalafil (Cialis) vardenafil (Levitra, Staxyn) avanafil (Stendra) alprostadil (Caverject, sildenafil 100mg generic Caverject Impulse, Edex, Muse) testosterone therapy, which is only used if you have low levels of testosterone.
