question: I have been taking 20 mg of pravachol daily for 3 years. My alt and ast blood levels have always been in the 30 s. They are now AST 45 and ALT 77. I am 60 years old 6 feet tall and weigh 182 lbs. The balance of my bloodwork is normal. I reacently had an ultrasound and everything came back normal. No iron issues or hepatits A,B or C . My dr is no concerned and says we will recheck in 6 months unless I have any symptoms. Do you concur with thi approach.
