The bottom line No known interaction

We found no known interaction between Asian Water Plantain and Oxycodone 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 Oxycodone states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Asian Water Plantain and Oxycodone

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 Oxycodone and Asian Water Plantain 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 Oxycodone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Oxycodone is filed under 6 classifications — including narcotic drugs, cytochrome p450 2d6 (cyp2d6) substrates, cns depressants. Asian Water Plantain has documented interactions with 1 drug class — the most serious being nephrotoxic drugs (minor) — and none of Oxycodone’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.

No Interaction Found — But Data Suggests Asian Water Plantain and Oxycodone May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

    Asian Water Plantain

    “There is limited information available about the potential adverse effects of Asian water plantain. Orally, it has been used as a part of Traditional Chinese Medicine (TCM) with apparent safety; there have been no reported adverse effects in most patients. However, one case of hepatotoxicity and nephrotoxicity has been reported with the use of a combination TCM product containing Asian water plantain.”

    Oxycodone

    Listed in the ADVERSE REACTIONS section of the FDA label for Oxycodone. Read the label on DailyMed ›

Reported for Asian Water Plantain but not commonly for Oxycodone: kidney problems and bleeding or bruising.

Effects for Oxycodone come from the ADVERSE REACTIONS section of its FDA label; effects for Asian Water Plantain come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Oxycodone Products Have a Food Rule — Asian Water Plantain Should Not Break It

At least one FDA label for a product containing Oxycodone says to take it with food. If you take Asian Water Plantain on an empty stomach out of habit, keep them separate — and take Oxycodone 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 Oxycodone 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.

( 2.2 , 5.1 , 5.2 , 5.3 ) XTAMPZA ER is administered, twice daily, every 12 hours, and must be taken with food .

From the Dosage and Administration section of the FDA label we read for Oxycodone — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

See Every Supplement That Interacts With Oxycodone

This page covers Asian Water Plantain only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Oxycodone page lists 145 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Kava (major).

By severity: 8 major · 114 moderate · 23 minor.

From our pharmacist’s overview on the Oxycodone page

“Oxycodone is a potent opioid painkiller, and anything that deepens its sedation can slow breathing itself, which is why this list deserves genuine respect. Of the 145 supplement and herbal ingredients on record, eight rate major, and the biggest cluster by far, 78 ingredients, adds extra drowsiness on top of the opioid's own.”

About Asian Water Plantain

What is Asian Water Plantain?

Asian Water Plantain
  • Promoting urination (diuretic)
  • Fluid retention and swelling
  • Urinary discomfort
  • Cholesterol and heart health support
  • Kidney and bladder support

Asian water plantain (Ze Xie) is a rhizome long used in traditional Chinese medicine, mainly as a diuretic and for fluid retention. Modern evidence is mostly limited to laboratory and animal studies, so its benefits in people are not well proven, and quality human safety data are lacking. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Alisma plantago-aquatica · Alismataceae · Dried rhizome (root-like stem), known as Rhizoma Alismatis or Ze Xie · Dried sliced rhizome, powders, decoctions (teas), capsules, and as part of multi-herb traditional Chinese medicine formulas

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

Asian Water Plantain: dosing

There is no well-established standardized dose for Asian water plantain as a supplement. In traditional Chinese medicine, the dried rhizome is typically used as part of a multi-herb formula prepared by a trained practitioner, not taken alone.If you use a commercial product, follow the directions on the label and do not exceed the recommended amount. Do not use it as a substitute for prescribed diuretics or other proven treatments.

About Oxycodone

What Is Oxycodone Used For?

Brand names: OxyContin, Roxicodone, OxyIR, Percolone, Oxecta, OxyNeo

Oxycodone is prescribed for pain severe enough to need daily, long-term opioid treatment — pain that hasn't responded well to non-opioid medicines or shorter-acting options. The extended-release form is designed for continuous pain control, not for occasional or as-needed use.

It is approved for adults and, in certain cases, for opioid-tolerant children 11 years and older who are already on opioid therapy. Because of the serious risks involved, it is reserved for situations where other approaches have genuinely fallen short.

Taking Asian Water Plantain and Oxycodone Together: Common Questions

Is it safe to take Asian Water Plantain with Oxycodone?
We do not list a known interaction between Asian Water Plantain and Oxycodone. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Asian Water Plantain and Oxycodone have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Asian Water Plantain and Oxycodone at the same time of day?
At least one FDA label for a product containing Oxycodone says to take it with food. If you take Asian Water Plantain on an empty stomach out of habit, keep them separate and take Oxycodone with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Oxycodone products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Asian Water Plantain and Oxycodone combination checked?
Interactions in our licensed database are recorded against drug classes. Oxycodone is filed under 6 classifications, and Asian Water Plantain has documented interactions with 1 drug class — none of Oxycodone's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Asian Water Plantain interact with any other medications?
Yes. Asian Water Plantain has 355 documented drug interactions in our database — Oxycodone is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Oxycodone interact with any supplements?
Yes. Oxycodone has documented interactions with 145 supplements in our database — Asian Water Plantain is not one of them. The Oxycodone interaction page linked on this page lists every one, ranked by severity.
