Recommendations
  • Consult with a healthcare provider before combining red yeast rice with rosuvastatin.
  • Consider Coenzyme Q10 to help mitigate potential muscle-related side effects.
Watch out for
  • Red yeast rice contains a natural statin (monacolin K, the same compound as lovastatin), so taking it with a prescription statin is effectively a double dose and raises the risk of muscle damage (myopathy) and liver strain. Do not combine — watch for unexplained muscle pain or weakness, or dark urine, and talk to your prescriber.
  • Monitor for muscle pain or weakness when taking red yeast rice with rosuvastatin; consult healthcare provider if symptoms occur.
