My creatinine value is abnormal, what types of medicine will improve it?

Depends: Need to know if level is high from poor blood flow to kidney (pre-renal), intrinsic kidney trouble (intra-renal) or blockage (post-renal). Most common kidney problems in us are from high blood pressure and diabetes. Control those diseases and creatinine should behave itself.

See a doctor: If creatinine value is abnormal,need evaluation & necessary investigations to assess which stage of renal failure. needs treatment accordingly.
