My mother is 82 and has dementia, diabetes and is in stage 4 CKD. Her average creatinine for about 2 years has been 1.7 and bun 55. She has always taken 40 mg of lasix daily as well as many blood pressure medicines which includes Dovian 80, Imdur 30, Hydralizine 75 mg 3 times day, and Coreg 6.25 x 2 day. Recently her creatinine has been from 2.4 to 2.7 with a bun of 105. Doctor changed Lasix to 80 mg and added Zaroxolyn 2.5 mg 3 times a week due to some fluid retention. Echo of heart is normal. Had breast cancer two years ago and takes Femara 2.5 mg. Potassium and oxygen test are normal. I am concerned that she is on too much fluid pills. Doctor tells me she is fine as long as potassium and oxygen is normal. She only has one kidney since 30 years old due to an accident.

It sounds like your mother may have chronic kidney disease (CKD), but I cannot make any other specific diagnosis based on the information that you present.  I am unable to make medical treatment recommendations without performing a complete history and physical examination.  I suggest that you consult with your mother’s primary care physician (PCP) and her nephrologist for advice.
