How should I take red yeast rice?
Red yeast rice contains an active ingredient called monacolin K, which has the same chemical structure as the active drug in the "statin" cholesterol medicine lovastatin (Advicor, Altoprev, Mevacor). For this reason, red yeast rice supplements may produce the same side effects and drug interactions as statin cholesterol medications produce.
The US Food and Drug Administration (FDA) considers red yeast products that contain more than trace amounts of this statin-identical ingredient to be illegal and unapproved drugs. Red yeast rice products sold within the United States are formulated not to contain high levels of monacolin K. However, red yeast rice with higher levels of monacolin K are still available in other countries.
When considering the use of herbal supplements, seek the advice of your doctor. You may also consider consulting a practitioner who is trained in the use of herbal/health supplements.
If you choose to use red yeast rice, use it as directed on the package or as directed by your doctor, pharmacist, or other healthcare provider. Do not use more of this product than is recommended on the label.
