Does Diovan cause increased protein in urine?

Diovan (valsartan) is an angiotensin II receptor blocker used to treat high blood pressure and heart failure. While it generally does not cause increased protein in urine, there may be instances where it can lead to mild proteinuria in some patients, particularly those with pre-existing kidney conditions. It is important for patients on Diovan to have their kidney function and protein levels monitored regularly. If significant proteinuria occurs, it is advisable to consult a healthcare provider.
