Been taking them for 11 years ever since had stents put in, no problems except that I suffered from a lack of energy. Did a lot of research and found out that statins deplete the body of the enzyme q10. With age the body produces less anyway so I take co-enzyme q10 100mg capsules every morning and have not had any problems. I did clear it with my gp and he showed interest in the research and cleared my use of them. With the first type of statin that I was given I had muscle cramps, my gp switched me to a different type of statin and I have not had problems since.
Taking statins if you have high cholesterol, over 5.0, is better than a heart attack.
