cholesterol

Four months ago my doctor found I had high cholesterol and trigylcerides were high also.  He put me on Crestor 20 mg one daily.  After 30 days cholesterol was lowered to normal levels, but trigylcerides were still high.  He added Tricor to my regimen and after 60 days both are normal, but my creatinine level has increased to 1.3 after having been 1.0 to 1.2.  I am a 66 yr old white male with only one kidney for the past 10 years. Can either or both of these drugs have caused the increased creatinine levels?.  The nephrectomy was for a non-cancerous cyst that was blocking the tube from the kidney to the bladder.

Both of the drugs can result in elevated levels of creatinine.
