Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Myrrh and Piroxicam 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 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.

Myrrh and Piroxicam

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 Piroxicam and Myrrh 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 Piroxicam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Piroxicam is filed under 9 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, anticoagulant/antiplatelet drugs. Myrrh has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and warfarin (coumadin) (moderate) — and none of Piroxicam’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 Myrrh and Piroxicam May Share Several of the Same Side Effects

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.

Effects for Piroxicam come from the ADVERSE REACTIONS section of its FDA label; effects for Myrrh come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 6,275 voluntary FDA FAERS reports for Piroxicam that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Piroxicam page

“Piroxicam (Feldene) is a potent, long-acting NSAID for arthritis pain, and since it already carries real stomach-bleeding risk on its own, my honest read is that this page calls for genuine caution rather than a quick skim. Most of the 285 interacting supplements share a single problem: they thin the blood or blunt platelets, stacking…”

About Myrrh

What is Myrrh?

Myrrh
  • Mouth and gum irritation
  • Sore throat
  • Minor wound and skin care
  • Digestive upset
  • Antimicrobial/antiseptic uses

Myrrh is a fragrant gum resin from Commiphora trees that has long been used in mouthwashes, throat remedies, and skin care. Modern evidence for most of its uses is limited and comes mostly from laboratory or small studies, so it should be viewed as a traditional remedy rather than a proven treatment. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy.

Commiphora myrrha · Burseraceae · Gum resin (and essential oil distilled from the resin) · Tincture, mouthwash/gargle, capsules, powder, essential oil, topical preparations, incense

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

Myrrh: dosing

There is no well-established standard dose of myrrh for any condition. Strengths vary widely between tinctures, mouthwashes, capsules, and essential oils.The safest approach is to follow the directions on the product label and not exceed them. Mouthwashes and gargles are usually diluted and not swallowed. Essential oil should never be swallowed and must be diluted before applying to the skin.

Taking Myrrh and Piroxicam Together: Common Questions

Is it safe to take Myrrh with Piroxicam?
We do not list a known interaction between Myrrh and Piroxicam. 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 Myrrh and Piroxicam have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
How was the Myrrh and Piroxicam combination checked?
Interactions in our licensed database are recorded against drug classes. Piroxicam is filed under 9 classifications, and Myrrh has documented interactions with 2 drug classes — none of Piroxicam'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 Myrrh interact with any other medications?
Yes. Myrrh has 88 documented drug interactions in our database — Piroxicam 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 Piroxicam interact with any supplements?
Yes. Piroxicam has documented interactions with 285 supplements in our database — Myrrh is not one of them. The Piroxicam interaction page linked on this page lists every one, ranked by severity.
