Are there any differences in the three products? It's hard to say because there have been no head-to-head tests. We know that all three work by blocking the same enzyme, and all three are pills (though Viagra is blue, Levitra is orange, and Cialis is yellow). The three do have some different properties, however. Perhaps the biggest distinction belongs to Cialis, which its marketers claim is effective for up to 36 hours -- or about five to seven times longer than the other two.
One last difference: Bayer and GlaxoSmithKline have tabbed tough guy and former NFL coach Mike Ditka as their Levitra spokesman. Even though he's about twice the age of Viagra pitchman and Rangers first baseman Rafael Palmeiro, "Coach Ditka" could back Palmeiro down with just a scowl.
