Lonsurf and nightly toilet visits

Tueffel Member Posts: 311


We are starting day 4 on the first cycle of Lonsurf. Last night Papa was hourly on the toilet. I am worried that something is wrong with the kidney. The oncologist warned us that the drug can cause the appearance of proteins in the urine. 

Did anyone have something similar? If so did it go away or is it a bad sign?

Take care
