Andiroba and Aluminum Hydroxide

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 Aluminum Hydroxide 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 Aluminum Hydroxide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aluminum Hydroxide is filed under 3 classifications — including antacids, oral drugs. Andiroba has documented interactions with 1 drug class — the most serious being anticonvulsants (minor) — and none of Aluminum Hydroxide’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.

From our pharmacist’s overview on the Aluminum Hydroxide page

“An antacid sounds harmless, and that is exactly why the supplement interactions with aluminum hydroxide (Amphojel, Gaviscon) deserve real attention before you combine it with much of anything. The most serious entry is activated charcoal, which can soak up many medications in the gut and sharply cut how much of them your body actually…”

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 ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Andiroba and Aluminum Hydroxide 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 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.
