Can anyone offer advice about cholesterol levels. My diabetic consultant is suggesting that I swap my daily dose of 20mg Simvastatin to 20mg Atorvastatin. My total cholesterol is 4.7, HDL 2.1, LDL 2.4 and triglycerides 0.4, with HDL ratio 2.2. I feel rather reluctant to change as Simvastatin seems to suit me. Any advice?
