I had intense muscle pain with simvastatin, which cleared after I stopped. A few months later, Dr tried me on Niaspan, the 3-week starter pack 500 mg working up to 1,000 mg. My BS went up from 6.7 to 7.2 (average) & muscle pains began again. The cholesterol treatment I have used since I was diagnosed is benecol/flora & oat bran. That reduced my Chol from 7.6 to 5.
Since reduced carb in May this year, my chol has dropped from 5.4 to 4.3. The total drop from 7.6 to 4.3 is 40% - much better than claimed.
Dietitian Ally recommends eating almonds to get the stannol esters we buy in benecol. I add ground almonds to my porridge-oats-free porridge.
