Side effects may be similar to those for the prescription drug lovastatin
. Heartburn, gas, bloating, muscle pain or
damage, dizziness, asthma, and kidney problems are possible. People with liver disease should not use red yeast products. These are the same possible side effects of statin use without any proven results.
In theory, red yeast may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding.
