Since Cialis can be used on a daily basis, it’s worth considering if you need an ED pill that’s “always on.” That said, Stendra’s lower incidence of side effects and quicker time to effect (like Viagra, Cialis also requires around one hour to take effect within the body) may make Stendra better for people who don’t see the benefits they want from Cialis.

Because the active ingredient in Viagra (sildenafil) is now available as a generic medication, it’s a significantly more affordable option than Stendra.
