Special Precautions of Red Yeast

• Red yeast is POSSIBLY SAFE for most people when taken by mouth for up to 3 months. There isn't enough information to know if taking it for longer periods is safe. It can cause stomach discomfort, heartburn, intestinal gas, and dizziness.
• Red yeast contains chemicals similar to the prescription drugs called "statins." Therefore, red yeast might also cause side effects similar to statin drugs, such as liver damage and severe muscle pain and muscle damage.
• There is also concern about product quality. Many red yeast rice products have been found to contain varying amounts of the statin-like chemicals. Some products may contain none and others may contain high amounts, which are more likely to cause serious side effects.
• Serious allergic reactions can occur after breathing in red yeast.
• Red yeast that is not fermented correctly may contain citrinin. Citrinin is a poison that may cause kidney damage.
• Pregnancy and breast-feeding: Red yeast is LIKELY UNSAFE during pregnancy. It has caused birth defects in animals. Not enough is known about the safety of using red yeast during breast-feeding. Don’t use during pregnancy or breast-feeding.
• Liver disease: Red yeast contains chemicals that are the same as the statin drug lovastatin. Like statin drugs, red yeast should be avoided in people with liver problems.
• Alcohol interacts with Red Yeast.
• Cyclosporine (Neoral, Sandimmune) interacts with Red Yeast.
• Gemfibrozil (Lopid) interacts with Red Yeast.
• Medications that can harm the liver (Hepatotoxic drugs) interacts with Red Yeast.
• Medications that decrease the break down of other medications in the liver (Cytochrome P450 3A4 (CYP3A4) inhibitors) interacts with Red Yeast.
• Medications used for lowering cholesterol (Statins) interacts with Red Yeast.

Red yeast can help lower cholesterol. Taking red yeast along with other medications used to lower cholesterol might increase the risk of adverse effects. Do not take red yeast if you are already taking medications used for lowering cholesterol.

• Niacin interacts with Red Yeast.

Benefits and uses of Red Yeast are

Red yeast supplements are manufactured by culturing Monascus purpureus yeast on rice at carefully controlled temperature and growing conditions to increase the concentrations of chemicals that lower blood cholesterol and triglycerides. These chemicals are similar to the prescription drugs known as "statins," including lovastatin (Mevacor) and others.

• Lowering high cholesterol. Some research showed that taking a specific red yeast product for two to three months could significantly lower total and “bad cholesterol” (low-density lipoprotein (LDL) cholesterol) levels and triglycerides (another type of blood fat). But, this specific product contained large amounts of a chemical similar to "statin" drugs, such as lovastatin. Statins are approved by the FDA to lower cholesterol. In the U.S., the FDA now considers this product and other red yeast products that contain statins to be illegal unapproved drugs. However, outside the U.S., these specific red yeast products are still available. Some red yeast products available in the U.S. these days contain little or no statins. It is not known if these products do much to reduce cholesterol levels in people with high cholesterol.Some other products still contain significant amounts of statins. One analysis shows that that some of these products can contain up to 5 mg of statins per tablet.
• Lowering high cholesterol and triglyceride levels caused by human immunodeficiency virus (HIV) disease (AIDS).
• Indigestion.
• Diarrhea.
• Improving blood circulation.
• Spleen and stomach problems.
