Hi, I am a 72 yr. old WF who has stage 3 kidney disease due to the chemo drugs I was given for lung cancer 4 yrs. ago. EFR 34, BUN 22, Creatinine 1.6, RBC 3.92, HDL CHO 37, LDL 85, TRI 317, A1C 6.8, Glucose160 non-fasting. - On Simvastatin 20mg, Amlodipine 5mg, Metoprolol 75mg, and Calcitroil .25mcg. PTH intact 89.6. Other blood work is fairly normal. BP 138/72, W-135, H 5 -4 I drink 2 glasses of wine/day. I am fairly active and am careful about my diet. My question is ,I am concerned about the side effects of Simvastatin; I do not have any heart issues. My Ferritin is very high-651. My kidney specialist is not sure why. Would you know why?
