Viagra, Cialis & Levitra Compared
They all provide a result, but which one is best?
With the introduction of a third drug for use in erectile dysfunction, we thought it may be useful to set out a brief comparison of the characteristics of each drug. Our patients report that the side effects of Cialis tadalafil tend to last longer, which is not surprising in view of its length of action, but are less marked than with the other preparations.
