Interaction Details
Ciprofloxacin is classified as belonging to the following category: Hepatotoxic Drugs
Theoretically, concomitant use might increase the risk of liver damage.
Red yeast rice contains varying levels of the drug lovastatin. Lovastatin can cause liver damage in some people. Some clinical research suggests that supplements containing red yeast rice might increase liver enzyme levels in some, but not all, participants. Cases of acute hepatitis have been associated with red yeast rice. Combining it with hepatotoxic drugs might further increase this risk.

Interaction Details
Ciprofloxacin is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Inhibitors
Theoretically, drugs that inhibit the CYP3A4 enzymes might increase levels of lovastatin from red yeast rice.
Red yeast rice contains varying levels of the statin drug lovastatin, which is metabolized by CYP3A4. Combining red yeast rice with CYP3A4 inhibitors might increase serum levels of lovastatin from red yeast rice.

Red Yeast Rice Overview
Red yeast rice is a type of fermented rice produced by the cultivation of a type of yeast called Monascus purpureus. The rice is soaked in water and then allowed to ferment with the yeast for several weeks. During the fermentation process, the rice turns a deep red color and develops a distinctive, slightly sweet, and sour taste.
Red yeast rice has a long history of use in traditional medicine and has been used as a natural remedy for a range of health conditions, including high cholesterol, high blood pressure, and heart disease. Red yeast rice is thought to work by inhibiting the production of cholesterol in the liver and by helping to improve circulation.
Red yeast rice contains a compound known as mevinolin, which is identical to the FDA-approved drug lovastatin.
Ciprofloxacin Overview
-
Ciprofloxacin is used to treat or prevent certain infections caused by bacteria such as pneumonia; gonorrhea (a sexually transmitted disease); typhoid fever (a serious infection that is common in developing countries); infectious diarrhea (infections that cause severe diarrhea); and infections of the skin, bone, joint, abdomen (stomach area), and prostate (male reproductive gland), Ciprofloxacin is also used to treat or prevent plague (a serious infection that may be spread on purpose as part of a bioterror attack) and inhalation anthrax (a serious infection that may be spread by anthrax germs in the air on purpose as part of a bioterror attack). Ciprofloxacin may also be used to treat bronchitis, sinus infections, or urinary tract infections but should not be used for bronchitis and sinus infections, or certain types of urinary tract infections if there are other treatment options. Ciprofloxacin extended-release (long-acting) tablets are used to treat kidney and urinary tract infections; however, some types of urinary tract infections should only be treated with ciprofloxacin extended release tablets if no other treatment options are available. Ciprofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections.
-
Antibiotics such as ciprofloxacin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
