Kidney creatanine count jumped from 1.3 to 1.8 in about two months. Am trying to figure out why. Am also using neurontin as a sleep aid as of 1/1/12. Other drugs include levoxyl 137, tricor 140, wellbutrin 300.My kidney function was severely compromised by extensive use of NSAIDS in 1988-1990 (ibuprofen).
