We found no known interaction between Myrcia and Ethinyl Estradiol, Norethindrone 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 Ethinyl Estradiol, Norethindrone states a food rule worth keeping to.
Myrcia and Ethinyl Estradiol, Norethindrone
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, Norethindrone and Myrcia 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Ethinyl Estradiol, Norethindrone
Interactions in our licensed database are recorded against drug classes, not just single drug names. Ethinyl Estradiol, Norethindrone is filed under 13 classifications — including progestin, contraceptive drugs, estrogens. Myrcia has documented interactions with 1 drug class — the most serious being levothyroxine (synthroid, others) (moderate) — and none of Ethinyl Estradiol, Norethindrone’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.

Some Ethinyl Estradiol, Norethindrone Products Have a Food Rule — Myrcia Should Not Break It
At least one FDA label for a product containing Ethinyl Estradiol, Norethindrone says to take it with food. If you take Myrcia on an empty stomach out of habit, keep them separate — and take Ethinyl Estradiol, Norethindrone 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 Ethinyl Estradiol, Norethindrone 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.
Tablets should be taken regularly with a meal or at bedtime.

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 Ethinyl Estradiol, Norethindrone page

About Myrcia
What is Myrcia?
- Blood sugar support
- Digestive upset and diarrhea
- Mild urinary complaints
- Astringent for the gut
- Traditional 'pedra-hume-caa' folk remedy
Myrcia is a group of tropical shrubs and trees in the myrtle family, used in South American folk medicine—often as a tea—mainly for blood sugar and digestive complaints. Human evidence is very limited, so it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you have diabetes or take other medicines.
Myrtaceae · Leaves (and sometimes bark) · Tea, dried leaf, capsules, liquid extracts
An interaction check asks whether these two react with each other — it does not ask whether Myrcia is a good idea for someone in your situation. Here is what our Myrcia record says about it on its own.
Myrcia: dosing
There is no established standardized dose for Myrcia. Traditional use is usually as a tea made from the dried leaves, but amounts vary widely and are not backed by clinical research.If you choose to try a commercial product, follow the directions on the label and do not exceed them.
