The bottom line No known interaction

We found no known interaction between Black Rice and Fluvastatin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Interaction report

Black Rice and Fluvastatin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Fluvastatin and Black Rice in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Black Rice at all — not against Fluvastatin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

What Fluvastatin’s Own FDA Label Lists

This is not an interaction — none of it involves Black Rice. These are the most notable effects listed in the ADVERSE REACTIONS section of Fluvastatin’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • A change in thyroid levels Worth acting on
  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Fluvastatin. Read the label on DailyMed › Black Rice’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Black Rice side to compare — that is a limit of the record, not a statement that Black Rice has no side effects.

Overlapping uses

What Fluvastatin Is Prescribed For, and What Black Rice Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Fluvastatin is a prescription medicine with approved uses on its FDA label. Black Rice is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Fluvastatin is prescribed for: Fluvastatin capsules are used alongside a low-cholesterol diet to lower total cholesterol, LDL-C (bad cholesterol), triglycerides, and a protein called apolipoprotein B, while raising HDL-C (good cholesterol), in adults with primary hypercholesterolemia (high cholesterol) or mixed dyslipidemia (multiple abnormal blood fat levels). Fluvastatin capsules are also approved for children and adolescents aged 10–16 with hereditary high cholesterol (heterozygous familial hypercholesterolemia) when diet alone hasn't worked enough. In adults who already have clinically evident coronary heart disease (CHD), both fluvastatin capsules and fluvastatin sodium extended-release tablets (including Lescol XL) are used to slow the buildup of plaque in coronary arteries and reduce the risk of needing coronary revascularization procedures (procedures to restore blood flow to the heart). Fluvastatin sodium extended-release tablets and Lescol XL are also approved to reduce LDL-C in adults with primary hyperlipidemia, and in patients aged 10 and older with hereditary high cholesterol who specifically require the higher daily dose.

Black Rice has been studied for:

  • Hyperlipidemia studied, not established Black Rice has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Black Rice for hyperlipidemia

    It is unclear if oral black rice is beneficial in patients with hyperlipidemia.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Fluvastatin on your own; if you are taking Black Rice for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Black Rice is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Black Rice reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Black Rice and Fluvastatin records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Black Rice

What is Black Rice?

Black Rice
  • Heart health support
  • Antioxidant intake
  • Digestive and gut health
  • Blood sugar and weight management
  • General nutrition

Black rice is a nutritious whole-grain food that is rich in fiber, plant protein, and antioxidant pigments called anthocyanins. Eaten as part of a balanced diet it is a healthy choice, but strong human evidence that black rice or its extracts treat or prevent specific diseases is still limited. Talk with your pharmacist or doctor before using concentrated black rice supplements.

Oryza sativa · Poaceae · Whole grain (bran and endosperm) · Whole grain, cooked rice, flour, rice bran, extracts, and supplement capsules

An interaction check asks whether these two react with each other — it does not ask whether Black Rice is a good idea for someone in your situation. Here is what our Black Rice record says about it on its own.

Black Rice: dosing

There is no established medicinal dose for black rice. As a food, a typical serving is a cooked portion similar to other rice, included as part of a balanced diet.For supplements or extracts, follow the directions on the product label, since amounts vary by product and have not been standardized.
