Does Citapin 500 Prescribed For Elevated Sugar Level Effect Kidneys?

Hi, may I answer your health queries right now ? Please type your query here...My mother, 71, is experiencing sugar level of 180 [pp] in the last 6 months and the creatinine level is also marginally higher at 1.5. She has been advised to take citapin 500 twice a day to control sugar. Will it effect kidneys. Will the creatinine rise further
