Spudville, the side effects of statins can be genetically initiated. You may be a slow metabolizer that causes your body to slowly convert the drug to an inactive form. This allows the blood level to exceed the therapeutic range, leading to side effects. The opposite can happen with fast metabolizers, resulting in sub-therapeutic levels. Likely you would be OK with a lower dose or an alternate statin. Lots of research being done on this in medical schools that have interest in personalized medicine.
Thank you for the information. I’m due to go in for the fist check up after being on it. Blood test etc. Maybe he’ll put me on another type.
