Corydalis Yanhusuo and Vancomycin

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 Vancomycin and Corydalis Yanhusuo 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 Vancomycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Vancomycin is filed under 2 classifications — antibiotic drugs, oral drugs. Corydalis Yanhusuo has documented interactions with 14 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and antihypertensive drugs (moderate) — and none of Vancomycin’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.

What Vancomycin’s Own FDA Label Lists

This is not an interaction — none of it involves Corydalis Yanhusuo. These are the most notable effects listed in the ADVERSE REACTIONS section of Vancomycin’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.

  • Hearing loss Worth acting on
  • Kidney problems Worth acting on mentioned in 11.2% of FDA reports for Vancomycin
  • Low potassium Worth acting on
  • A severe skin reaction Worth acting on mentioned in 4.1% of FDA reports for Vancomycin
  • Wheezing Worth acting on
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Anemia Worth acting on
  • A higher chance of infection Worth acting on mentioned in 7.1% of FDA reports for Vancomycin

Showing the 10 most notable of 33 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Vancomycin. Read the label on DailyMed › Where a percentage is shown, it is the share of 64,480 voluntary FDA FAERS reports for Vancomycin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Corydalis Yanhusuo’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Corydalis Yanhusuo side to compare — that is a limit of the record, not a statement that Corydalis Yanhusuo has no side effects.

About Corydalis Yanhusuo

What is Corydalis Yanhusuo?

  • Pain relief
  • Menstrual cramps
  • Headache
  • Stress and sleep support
  • Stomach and abdominal discomfort

Corydalis yanhusuo is a traditional Chinese herb used mainly for pain. Some early laboratory and animal research suggests its compounds may affect pain and the nervous system, but high-quality human studies are limited, so its true benefits and long-term safety are not well established. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Corydalis yanhusuo · Papaveraceae · Dried tuber (rhizome) · Capsules, tablets, powders, tinctures, and as part of traditional herbal formulas

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

Corydalis Yanhusuo: dosing

There is no well-established standard dose for corydalis. Doses used in traditional practice and in studies vary, and products differ in how concentrated they are.The safest approach is to follow the directions on the product label and to use the lowest amount that seems reasonable. Because product quality varies, choose brands that use third-party testing when possible.

About Vancomycin

What Is Vancomycin Used For?

Brand names: Vancocin, Vancoled

Vancomycin is used to fight serious bacterial infections caused by certain hard-to-treat bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). When given intravenously (by IV), it treats conditions like septicemia (a serious bloodstream infection), infective endocarditis (infection of the heart valves), skin and skin structure infections, bone infections, and lower respiratory tract infections.

When taken by mouth — as capsules or oral solution (brands include Vancocin and Firvanq) — vancomycin treats Clostridioides difficile-associated diarrhea (C. diff) and staphylococcal enterocolitis (a gut infection caused by Staphylococcus aureus). It's important to know that the oral form does not work for bloodstream or other serious infections, and the IV form does not work for C. diff or gut infections — each route has its own specific uses.

Most-Reported Side Effects for Vancomycin

From FAERS, the FDA’s public side-effect reporting system (65,520 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Acute kidney injury 4,892 reports
Fever 4,046 reports
Drug reaction with eosinophilia and systemic symptoms 2,695 reports
Renal failure 2,468 reports
Diarrhea 2,392 reports
