I have lupus and recently dx with 3rd stage kidney failure. Have been treated in the past with valsartan hctz 160/12.5mg. Changed primary care physician and new physician prescribed lisinopril hctz 10/12.5 And my systolic numbers have gone up but the diastolic number (70) has stayed the same since using lisinopril and I have gained about 7 pounds. I thought people with lupus shouldn't use hydrochlorothiazide? AND I'm also vitamin D deficient (severe) please advise.
