Red Yeast Rice contains a statin....if you are vulnerable to any statin, the lovastatin (Merck's Mevacor) and its congeners in the Rice will have similar effects.
For many years, the FDA blocked the sale of the Red Yeast Rice products that were the most effective. Not all Red Yeast Rice products are equal. Some are stronger than others. PN damage is a cumulative effect of all statins, and once a person has symptoms of PN, it is best to avoid them all IMO. But it is your choice in the end. We've had people here decide to continue statins, even when in terrible pain. I provide the information that your doctor probably doesn't know about, and it is up to you to balance it all for yourself.

I'd really suggest going all statin free if you are expecting any improvement or want to halt progression of PN at this point.
If you decide to do Red Yeast Rice, you will have to continue with the CoQ-10 as well. Since the enzyme the Rice blocks is the same one that Big Pharma's statins block.
