Levitra will work in some men who don't respond to Viagra
Reps are saying that Levitra will work in some men who don't respond to Viagra.
It's true...but not that surprising. Someday you'll also likely hear that Viagra can work when Levitra doesn't.
Explain to patients that this doesn't necessarily mean that one drug is more effective. It just means that some people respond differently to drugs in the same class.
