Amaranth and Ferric Carboxymaltose

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 Ferric Carboxymaltose 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 Ferric Carboxymaltose, 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 Ferric Carboxymaltose’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 Ferric Carboxymaltose’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. 7 of them are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on
  • A severe skin reaction Worth acting on
  • Raised blood pressure Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • An allergic reaction Worth acting on
  • Migraine
  • Dry skin
  • A change in taste

Showing the 10 most notable of 23 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ferric Carboxymaltose. Read the label on DailyMed › Where a percentage is shown, it is the share of 1,619 voluntary FDA FAERS reports for Ferric Carboxymaltose that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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 Ferric Carboxymaltose 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. Ferric Carboxymaltose 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.

Ferric Carboxymaltose is prescribed for: Ferric carboxymaltose injection treats iron deficiency anemia (IDA) in adults and children aged 1 year and older who cannot tolerate oral iron or haven't responded well to it. It is also approved for adults with non-dialysis dependent chronic kidney disease who have iron deficiency anemia. Additionally, ferric carboxymaltose injection is used in adults with heart failure (New York Heart Association class II or III) who have iron deficiency — specifically to help improve their ability to exercise.

Amaranth has been studied for:

  • Iron deficiency anemia studied, not established Amaranth has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Amaranth for iron deficiency anemia

    Preliminary clinical research in children shows that consuming 150 grams of bread made with 70% amaranth grain, providing approximately 22.3 mg iron, for 6 months decreases the prevalence of anemia by 61% and increases hemoglobin levels by 8% when compared with consuming bread containing 100% maize grain. The amaranth used in this study was processed to reduce phytic acid content in order to improve iron absorption.

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 Ferric Carboxymaltose 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.
