Red Yeast Rice and Pitavastatin

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Red Yeast Rice interacts with whole categories of medication. Pitavastatin falls into 2 of those categories, so it can interact with Red Yeast Rice in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

HEPATOTOXIC DRUGS

1 of 2

Why this applies to Pitavastatin

Pitavastatin falls under HEPATOTOXIC DRUGS — the group Red Yeast Rice interacts with.

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.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: red yeast rice naturally contains lovastatin, which is itself a statin, just like your pitavastatin (Zypitamag, Nikita). So taking both means you're essentially doubling up on statins. That's the real concern. Both can put a little extra workload on the liver, and stacking them may raise your chances of liver irritation or higher liver enzyme levels. It could also bump up the more typical statin side effects, like muscle aches, soreness, or weakness.

To be fair, this is mostly a theoretical, by-the-numbers caution, not something proven to harm everyone. Red yeast rice products also vary a lot in strength. Still, I wouldn't combine them on your own. Please check with your pharmacist or doctor first.

HMG-CoA REDUCTASE INHIBITORS ("Statins")

2 of 2

Pitavastatin also falls under HMG-CoA REDUCTASE INHIBITORS ("Statins").

Theoretically, taking red yeast rice with other statins might increase the risk of potential adverse effects.
Red yeast rice contains varying levels of the statin drug lovastatin and might result in supratherapeutic levels when used with other statins. Based on evaluation of data from the US Food and Drug Administration's adverse event reporting system (FAERS), it is recommended that red yeast rice products be avoided in people taking prescription statins.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple way to think about this: red yeast rice naturally contains lovastatin, which is itself a statin. So if you take it alongside your pitavastatin (Zypitamag, Nikita), you're essentially stacking two statins on top of each other. That's like quietly raising your statin dose without anyone planning it, and because red yeast rice products aren't standardized, you can't really know how much you're getting.

What could that look like in real life? More of the typical statin side effects, mainly muscle aches, soreness, or weakness, and a higher chance of liver irritation. This concern is based on pharmacology and reported cases rather than hard head-to-head studies, so it's more of a sensible caution than a guarantee. Still, I'd talk with your pharmacist or doctor before combining the two.

From our pharmacist’s overview on the Pitavastatin page

“Liver strain runs through the serious end of pitavastatin's (Zypitamag, Nikita) supplement interactions, and this list deserves real care rather than a quick skim. The biggest cluster of worrisome entries is herbs and ingredients with their own record of liver injury, and alcohol belongs to that group too, with beer and wine both carry…”

About Red Yeast Rice

What is Red Yeast Rice?

Red Yeast Rice
  • High cholesterol
  • Heart health
  • Metabolic syndrome
  • Statin alternative

Red yeast rice contains monacolin K, which is chemically identical to the prescription statin lovastatin, and it can lower LDL ('bad') cholesterol. Because of this, it carries the same risks as statin drugs, and the amount of active ingredient varies widely between products. Always talk to your pharmacist or doctor before using it, especially if you have liver problems or take other medicines.

About Pitavastatin

What Is Pitavastatin Used For?

Brand names: Zypitamag, Nikita

Pitavastatin tablets are used alongside a cholesterol-lowering diet to reduce LDL-C (low-density lipoprotein, or "bad" cholesterol) in adults with primary hyperlipidemia (high cholesterol not caused by another disease).

Livalo, Pitavastatin Calcium (tablet), and some other pitavastatin tablet products are also approved for adults and children aged 8 years and older with heterozygous familial hypercholesterolemia (HeFH) — an inherited condition that causes very high LDL-C from birth. Zypitamag is labeled only for adults with primary hyperlipidemia; its labeling does not include the pediatric HeFH indication.
