Condurango and Aprepitant

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 Aprepitant and Condurango 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 Condurango at all — not against Aprepitant, 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 Aprepitant’s Own FDA Label Lists

This is not an interaction — none of it involves Condurango. These are the most notable effects listed in the ADVERSE REACTIONS section of Aprepitant’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on
  • Dehydration Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Aprepitant. Read the label on DailyMed › Condurango’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Condurango side to compare — that is a limit of the record, not a statement that Condurango has no side effects.

Overlapping uses

What Aprepitant Is Prescribed For, and What Condurango Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Aprepitant is a prescription medicine with approved uses on its FDA label. Condurango is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Aprepitant is prescribed for: Aprepitant prevents nausea and vomiting. It is always used together with other anti-nausea medicines for chemotherapy. Uses depend on the product. Emend (capsules and oral suspension) and aprepitant capsules are used for chemotherapy-related nausea and vomiting.

Cinvanti (intravenous) is also for chemotherapy in adults. Aponvie (intravenous) and aprepitant capsules are used to prevent nausea and vomiting after surgery in adults. It has not been studied for treating nausea and vomiting that has already started.

Condurango has been studied for:

  • Cancer studied, not established Condurango has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Condurango for cancer

    Although there has been interest in using oral condurango for cancer, there is insufficient relable information about the clinical effects of condurango for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Aprepitant on your own; if you are taking Condurango for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Aprepitant

This page covers Condurango only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aprepitant page lists 158 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 · 116 moderate · 39 minor.

From our pharmacist’s overview on the Aprepitant page

“Aprepitant (Emend, Cinvanti) keeps chemotherapy patients from vomiting, so a supplement that undoes it mid-cycle is a problem, and I read this list with genuine vigilance. Nearly all 158 entries touch CYP3A4, the liver enzyme that clears aprepitant.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Condurango is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).

About Condurango

What is Condurango?

  • Digestive upset
  • Loss of appetite
  • Stimulating gastric secretion
  • Indigestion and bloating
  • Traditional tonic

Condurango is the bark of a South American vine traditionally used as a bitter to stimulate appetite and ease digestive complaints. Modern scientific evidence supporting any of these uses is very limited, and its safety has not been well studied, so use caution and talk with a pharmacist or doctor before trying it.

Marsdenia condurango · Apocynaceae · Dried bark · Tincture, fluid extract, tea (decoction), homeopathic preparations

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

Condurango: dosing

There is no well-established or standardized dose of condurango. Traditional preparations included tinctures, fluid extracts, and bark teas, but the amounts vary widely between products.If you choose to use a condurango product, follow the directions on the label and do not exceed them.
