If a patient meets the criteria for nitro assistance, odds are they don't take Viagra and their doctor has made it clear that it is NOT a wise choice. But, most people find the contraindication as a joke and embarrassing to ask someone, which I agree is a potential problem especially when you don't have emergent fluid replacement at your disposal. But, I don't know anyone who this has happened to.
Just an FYI on this topic.
Apparently some guys use their prescription nitro paste as a topical erectile enhancer.
