... had numerous other issues throughout the last three weeks - too many to mention. They now have him on Vancomycin and Cefepime Hydrochloride. I have reviewed the side effects for both these meds; however, he already has almost all of these side effects prior to be put on these meds. Anyone have any thoughts or suggestions. The only side effect he does not and did not have prior to and does not yet have is hives/rashes
