Andiroba and Ethinyl Estradiol, Ethynodiol Diacetate

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 Ethinyl Estradiol, Ethynodiol Diacetate 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 Ethinyl Estradiol, Ethynodiol Diacetate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ethinyl Estradiol, Ethynodiol Diacetate is filed under 11 classifications — including contraceptive drugs, estrogens, cytochrome p450 1a2 (cyp1a2) inhibitors. Andiroba has documented interactions with 1 drug class — the most serious being anticonvulsants (minor) — and none of Ethinyl Estradiol, Ethynodiol Diacetate’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 Ethinyl Estradiol, Ethynodiol Diacetate page

“The stakes here are pregnancy prevention, so I read this list with genuine seriousness. Ethinyl estradiol with ethynodiol diacetate (Zovia, Demulen, Kelnor) is a combined birth control pill, and the interactions that concern me most are the ones that can quietly weaken it.”

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.
