Levitra is generally safe when used in moderation. It has not been out long enough to conclude that there are no definitely zero long-term side effects. In clinical trials, there does not seem to be a reduction of erections, nor anatomic damage, after prolonged use.
If you find that you are needing Levitra excessively, you may want to discuss other treatments for the erectile dysfunction in consultation with a urologist.
Followup with your personal physician is essential.
