The bottom line No known interaction

We found no known interaction between Andiroba and Norgestrel 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.

Andiroba and Norgestrel

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 Norgestrel 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 Norgestrel

Interactions in our licensed database are recorded against drug classes, not just single drug names. Norgestrel is filed under 5 classifications — including contraceptive drugs, cytochrome p450 1a2 (cyp1a2) inhibitors, hepatotoxic drugs. Andiroba has documented interactions with 1 drug class — the most serious being anticonvulsants (minor) — and none of Norgestrel’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 Norgestrel page

“Norgestrel (Ovrette) is a progestin-only birth control pill, so the biggest danger on this page is not a strange side effect but a pill that quietly stops working. That risk makes this a page for genuine vigilance.”

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 Norgestrel 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.

Andiroba: dosing

About Progestin-Only (norethindrone) Oral Contraceptives

What Is Progestin-Only (norethindrone) Oral Contraceptives Used For?

Brand names: Ovrette, Orval 21

Norethindrone progestin-only pills — sometimes called the "mini-pill" — are used solely to prevent pregnancy. They do not contain estrogen, which makes them an option for women who cannot or prefer not to use estrogen-containing contraceptives.

When taken perfectly (same time every day, no missed pills), fewer than 1 in 100 women will become pregnant in the first year. With typical use, that number rises to about 9 in 100 — mostly because of late or skipped pills. Consistency is everything with this method.

Most-Reported Side Effects for Norgestrel

From FAERS, the FDA’s public side-effect reporting system (2,254 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Heavy menstrual bleeding 247 reports
Pregnancy on oral contraceptive 210 reports
Intermenstrual bleeding 182 reports
Polymenorrhoea 157 reports
Nausea 143 reports
