Are there are any potential contra indications
in that Viagra should not be taken by a person who takes
L-
Arginine? If so, is the contraindication just for that day? In other words, would I be safe if I did not take L-Arginine on the day I took Viagra? Or, do I have to stop taking L-Arginine completely if I am going to occasionally take Viagra (i.e. take Viagra once a week)? Thank you for your response.
