http://www.medications.com/effect/view/40513 Not sure but didn't have a problem with sugar until a month after starting Lipitor 80mg. Leg muscles feel like they are going to cramp when I move quickly and I now have much fatigue both muscles and general. AND, I now have to start Metformin for diabetes.

I doubt that it caused your diabetes. Drs. are drug-happy. There are many natural products to help health issues. http://www.medications.com/effect/view/40513?item=18751 Fri, 10 Apr 2009 00:34:50 -0400 http://www.medications.com/effect/view/40513?item=18754 taking high dose of lipitor will show the side effect much quiker than low dose .so the best way to know about your blood sugar try to stop it and see if the symptom goes away that would be definately lipitor .if you continue with high dose for few months http://www.medications.com/effect/view/40513?item=18754
