question: I am on Linisinoprol 20 mg since June 13, 2013. because my doctor says that there is an excess of protein in my urine. Will this medicine cause my kidnesys to fail  and will iit lead to cirohosis of the liver of which both side effects I have read about on line?  Will I have to take this med all my life to prevent the protein leak?  Is there a safer or alternative drug.? I am also on Hydrochlorothiazide 12.5 mg for high blood pressure and Diltiazem  240 mg for high blood as well as potassium.
