@wgj Farxiga is used for both diabetes and kidney disease. The difference is the strength meaning that endocrinology use 5 mg and nephrologists use 10 mg. With both, there can be multiple severe side effects such as urinating frequently at night causing lack of sleep. I went off of it twice and my creatinine eGFR improved but there are others who continued with Farxiga with good results. As others have said, good daily hydration levels and watching intake of sodium, potassium, and phosphorus go a long way to improving your eGFR score. You may also wish to use a 24 hour urine test which many nephrologists like for kidney function in complimenting eGFR.

My labs from the nephrologist will be this Thursday. I went to my GP last Thursday and asked him to test one week off of Farxega to see if there was improvement. My GFR went from 26 to 44. That is the highest it has been in two years. Different lab but that shouldn't make that big of a difference, should it? I am still doing Forteo for bones. I called the Forteo company and asked if they had any information on reduced kidney function. They said in all their clinical trials there were no problems with creatinine and other numbers that would indicate an effect on kidneys. However, I neglected to ask if all the participants in the trials had normal function to begin with. Prior to the low number, I was drinking 64 ounces of water plus almond milk and a cup of tea every day. When I got the GFR of 26, I upped the water to 74 ounces, lowered my protein intake and stopped the Farxega. With only those changes, the number jumped in one week. I will report again when I hear from the nephrologist the end of this week. Fingers crossed.
