I took Torsemide two years ago first recommended by a nephrologist and ended up at the Mayo ER after a few months. I stopped that immediately as my GFR went to Stage 4. Towards the end of last year, I stopped taking Farxiga because my nephrologist at the time said to do so. It was a 5mg dose and the kidney dose is 10mg. I started again with a new Mayo nephrologist and he said it was good. After another 4 months, I stopped again because I touched the tip of Stage 4 with fatigue, frequent urination, and nauseous. It was not worth it. I feel so much better now that I am off it. As I said in another post, just because a company advertises so frequently on the TV daily does not make it a great product. For me, it was not helpful in any way.
