Hi, I'm Piotr from Poland.

Please write how your blood creatinine increased after starting Tolvaptan treatment?

I have been taking tolvaptan for less than two months. when I started my creatinine was 1.7 mg / dl and now it is 1.94 mg / dl. In the meantime, I did tests 3 times and there was a creatinine increase in each of them. is it the tolvaptan effect? I read that at the beginning of the treatment there is a sudden drop in egfr, how was it for you?

I cordially greet everyone.
