For Generic Viagra vs Brand Viagra, documenting what improved, what did not improve, when adverse effects appeared and whether doses were missed gives the next review something concrete to use. A previous experience with Generic Viagra vs Brand Viagra should be interpreted alongside changes in diagnosis, concomitant medicines and current health status instead of treated as permanent proof.",
