@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.
