The bottom line No known interaction

We found no known interaction between Peru Balsam and Medroxyprogesterone 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.

Peru Balsam and Medroxyprogesterone

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 Medroxyprogesterone and Peru Balsam 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Peru Balsam at all — not against Medroxyprogesterone, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Peru Balsam Itself Has Been Linked To

This is not an interaction — nothing below involves Medroxyprogesterone. It is the side-effect record for Peru Balsam on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Peru Balsam, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Kidney problems Worth acting on Additional detail

    “Peru balsam can cause kidney damage when taken orally or applied topically in large amounts (18). Topical use is associated with allergic contact dermatitis and other skin reactions (2,18).”

    “There are numerous reports of Peru balsam and its extracts causing allergic contact dermatitis, particularly when present in fragrances, cosmetics, and topical medicines. Among people who undergo patch testing for allergic contact dermatitis, reactions to Peru balsam occur in 4% to 8.4%, of whom 70% are women.”

  • A skin rash Additional detail

Everything above comes from the Natural Medicines adverse-effect record for Peru Balsam — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Medroxyprogesterone’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Medroxyprogesterone column appears here.

See Every Supplement That Interacts With Medroxyprogesterone

This page covers Peru Balsam only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Medroxyprogesterone page lists 139 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 95 moderate · 41 minor.

From our pharmacist’s overview on the Medroxyprogesterone page

“Medroxyprogesterone (Provera, Depo-Provera) only works if its blood level holds steady, and 121 of the 139 supplements and herbs on file can shift that level through a single liver enzyme, CYP3A4. That makes this a list to respect, with three entries rated major.”

About Peru Balsam

What is Peru Balsam?

  • Wound and skin healing
  • Hemorrhoids
  • Coughs and sore throat
  • Antimicrobial and antiseptic
  • Diaper rash and minor skin irritation

Peru Balsam is a fragrant tree resin used mainly in topical products for wounds, hemorrhoids, and skin care, and sometimes in cough and throat remedies. Evidence for most uses is limited and largely traditional, and it is a well-known cause of allergic skin reactions, so use it cautiously and check with your pharmacist or doctor first.

Myroxylon balsamum var. pereirae · Fabaceae · Balsam (resin) obtained from the tree bark · Topical ointments, creams, suppositories, lozenges, and as a fragrance ingredient

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

Peru Balsam: dosing

There is no well-established standardized dose for Peru Balsam. It is usually found as one ingredient in finished topical products, lozenges, or syrups rather than as a stand-alone supplement.Follow the directions on the specific product label, and use the smallest amount needed.

From our Peru Balsam monograph — the full record covers uses, side effects and every documented interaction.

What Is Medroxyprogesterone Used For?

Brand names: Provera, Amen, Depo-Provera, Depo-subQ Provera 104

Medroxyprogesterone is used for different conditions depending on the product form. The injectable forms — including Depo-Provera and intramuscular medroxyprogesterone acetate injectable suspension — are used to prevent pregnancy. Depo-subQ Provera 104 (the subcutaneous injection) is also approved to manage pain associated with endometriosis.

The tablets are also used to prevent endometrial hyperplasia (abnormal thickening of the uterine lining) in postmenopausal women with a uterus who are taking daily conjugated estrogens.
