I began with a drug called Mevacor but my cardiologist soon switched me over to Lipitor. There was a period of liver screening at the first. Since there is finally a generic form of Lipitor I've changed to it. It's considerably cheaper than Lipitor.
To my knowledge I've not had any ill effects from it. My cholesterol has dropped from well over 200 to less than 100 at my last physical. In fact, one of the drugs I took was Zetia and I have discontinued taking it because of the very low lipids count. It should go without saying that I had to make some diet changes but none so sever that they were a problem.
