Monascus Purpureus Possible Side Effects

Monascus purpureus or red yeast rice is an herbal supplement derived from the fermentation of rice in China. Despite its effectiveness in the treatment of high cholesterol and stomach or spleen disorders, moascus purpureus poses a risk for side effects in some patients.

Types of Side Effects

• Possible side effects of monascus purpureus include stomach pains, gas, bloating and dizziness.

Time Frame

• According to the Natural Medicines Comprehensive Database recommends that moascus purpureus is only safe for short-term usage of three months or less because its effects for longer periods of time are unknown and not well-studied.

Features: Drug Interactions

• Monascus purpureus mimics the actions of prescription medications called statins that are known to cause liver damage in some patients; particularly those also using acetaminophen, seizure medications like Tegretol, antibiotics like erythromyacin and anti-fungal medication like itraconazole.

Risks

• Like statin medications, there is a risk for muscle and kidney damage while taking monascus purpureus. The condition it contributes to is known as rhabdomyolysis, a breakdown of muscle fibers that leads to kidney dysfunction or sudden failure.

Considerations

• If you have a medical history of liver disease, you should not take monascus purpureus due to its potential side effects. The Natural Medicines Comprehensive Database also advises that the drug is not safe for pregnant or nursing women.
