The bottom line No known interaction

We found no known interaction between Andiroba and Ferric Citrate 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. Additionally, although there is no interaction, the label for Ferric Citrate states a food rule worth keeping to.

Andiroba and Ferric Citrate

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 Citrate and Andiroba 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.

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.

How we checked

Why No Interaction Is Listed for Ferric Citrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ferric Citrate is filed under a single classification — oral drugs. Andiroba has documented interactions with 1 drug class — the most serious being anticonvulsants (minor) — and none of Ferric Citrate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Ferric Citrate’s Own FDA Label Lists

This is not an interaction — none of it involves Andiroba. These are the most notable effects listed in the ADVERSE REACTIONS section of Ferric Citrate’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. 3 of them are worth acting on rather than waiting out — marked below.

  • High potassium Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • Cough
  • Constipation
  • Stomach pain
  • Diarrhea
  • Vomiting
  • Nausea

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

How to take them

Some Ferric Citrate Products Have a Food Rule — Andiroba Should Not Break It

At least one FDA label for a product containing Ferric Citrate says to take it with food. If you take Andiroba on an empty stomach out of habit, keep them separate — and take Ferric Citrate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ferric Citrate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.2 ) 2.1 Dosage for Hyperphosphatemia in Chronic Kidney Disease on Dialysis The recommended starting dose is 2 tablets, swallowed whole, 3 times per day with meals.

From the Dosage and Administration section of the FDA label we read for Ferric Citrate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Ferric Citrate page

“Ferric citrate (Auryxia) does its work in the gut, binding dietary phosphate in kidney disease or supplying iron, and all 17 supplements on this list can interfere with how oral medicines get absorbed. That is worth real caution, starting with the single major-rated entry, activated charcoal, which adsorbs many drugs directly and can m…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Andiroba 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 Andiroba reference on this page ↓

About Andiroba

What is Andiroba?

Andiroba
  • Skin care and wound healing
  • Insect repellent
  • Muscle and joint aches
  • Anti-inflammatory skin conditions
  • Hair and scalp care

Andiroba is an oil pressed from the seeds of an Amazonian tree, used mainly on the skin for inflammation, minor wounds, aches, and as an insect repellent. Most evidence comes from laboratory and animal studies, so its benefits in people are not well proven. It is most often used topically; avoid internal use and use during pregnancy or breastfeeding because safety has not been established.

Carapa guianensis · Meliaceae · Seed oil (mainly), bark, and leaves · Topical oil, skin and hair products, soaps, balms, candles (insect repellent)

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

Andiroba: dosing
