The bottom line No known interaction

We found no known interaction between Amaranth 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.

Amaranth 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 Amaranth 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 Amaranth 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.

Amaranth safety at a glance

Amaranth overall Use caution Generally safe as a food, but medicinal supplement doses are not well studied.
Pregnancy Use caution Food amounts are likely fine, but avoid concentrated medicinal doses due to lack of safety data.
Breastfeeding Use caution Food amounts are likely fine, but supplement-level doses have not been studied.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Fluvastatin’s Own FDA Label Lists

This is not an interaction — none of it involves Amaranth. 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 › Amaranth’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Amaranth side to compare — that is a limit of the record, not a statement that Amaranth has no side effects.

Overlapping uses

What Fluvastatin Is Prescribed For, and What Amaranth 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. Amaranth 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.

Amaranth has been studied for:

  • Hypercholesterolemia studied, not established Amaranth has been studied for this. Natural Medicines rates the evidence: Possibly Ineffective Read what the research shows

    Amaranth for hypercholesterolemia

    Preliminary clinical research shows that eating muffins made with amaranth flour or taking oral doses of amaranth oil 3-18 mL daily while following a reduced fat diet for 3-4 weeks does not reduce serum cholesterol levels more than the reduced fat diet alone.

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 Amaranth for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Amaranth

What is Amaranth?

Amaranth
  • Nutrition and as a gluten-free grain
  • High cholesterol
  • Diarrhea and digestive upset
  • Mouth and throat irritation (gargle)
  • Wound and skin care (traditional)

Amaranth is a nutritious plant whose seeds are used as a gluten-free pseudocereal and whose leaves are eaten as a vegetable. It is generally considered safe as a food, but evidence for its medicinal benefits (such as lowering cholesterol) is limited and mostly preliminary. Talk to your pharmacist or doctor before using concentrated supplements.

Amaranthus spp. · Amaranthaceae · Leaves, seeds, seed oil, roots, and whole plant · Seeds and flour (pseudocereal), leafy vegetable, seed oil, capsules, powders, and teas

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

Amaranth: dosing

There is no established standardized medicinal dose for amaranth. As a food, it is simply prepared and eaten like other grains or leafy vegetables.If you choose a supplement, oil, or capsule, follow the directions on the product label, since the amount of active ingredients can vary widely between products.

Taking Amaranth and Fluvastatin Together: Common Questions

Is it safe to take Amaranth with Fluvastatin?

Are Amaranth and Fluvastatin used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Amaranth in each. That is a conversation for your prescriber, especially if Fluvastatin is being adjusted to a target.
Does Fluvastatin interact with any supplements?
Yes. Fluvastatin has documented interactions with 128 supplements in our database — Amaranth is not one of them. The Fluvastatin interaction page linked on this page lists every one, ranked by severity.
