After several trials and error, I have settled on Benzepril HCL. I went through three other prescriptions due to hives and insane itching.
Living with Celiac Disease gave me the ability to trouble shoot a situation. I examined everything that went into my mouth on a regular basis.
I was taking a Fish Oil suppliment with my blood pressure meds and cholestrol meds. Apparently, for me, it was reactive. I stopped the Fish Oil and the itching left after about a weeks time.
Everyone is different, but hope this helps. Getting old sucks!
If you doctor can't find a good fit for you, get a new doctor!
