Drug & supplement interaction

Guaiac Wood + Meclofenamate

Meclofenamate brand name: Meclomen.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Guaiac Wood and Meclofenamate 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 Meclofenamate 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.

Interaction report

Guaiac Wood and Meclofenamate

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 Meclofenamate and Guaiac Wood 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.

Guaiac Wood safety at a glance

Guaiac Wood overall Use caution Mostly used externally or as a scent; little safety data for internal use.

How we checked

Why No Interaction Is Listed for Meclofenamate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Meclofenamate is filed under 5 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Guaiac Wood has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Meclofenamate’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 Guaiac Wood and Meclofenamate 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.

Effects for Meclofenamate come from the ADVERSE REACTIONS section of its FDA label; effects for Guaiac Wood 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 Meclofenamate Products Have a Food Rule — Guaiac Wood Should Not Break It

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

If gastrointestinal complaints occur (see WARNINGS and PRECAUTIONS ), meclofenamate sodium may be administered with meals or with milk (see CLINICAL PHARMACOLOGY for a description of food effects).

From the Dosage and Administration section of the FDA label we read for Meclofenamate — 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.

From our pharmacist’s overview on the Meclofenamate page

“Meclofenamate (Meclomen) is a prescription NSAID for pain and arthritis, a class of drug that is already hard on the stomach and kidneys, so this list deserves real care rather than a quick skim. Five of its 32 supplement and herbal interactions rate major, clustered around two dangers: alcohol (beer and wine both raise the risk of sto…”

About Guaiac Wood

What is Guaiac Wood?

  • Fragrance in perfumes and soaps
  • Aromatherapy and relaxation
  • Traditional anti-inflammatory remedy
  • Skin care products
  • Traditional joint and arthritis support

Guaiac wood is mainly valued for its sweet, smoky-rosy aroma and is used widely as a fragrance ingredient and in aromatherapy. There is very little high-quality human research supporting any health or medical benefit, so it should be thought of as a scent rather than a proven remedy. If you want to use it, talk to your pharmacist or doctor first, and avoid taking it by mouth.

Bulnesia sarmientoi · Zygophyllaceae · Wood and essential oil (also called guaiacwood oil) · Essential oil, aromatherapy blends, soaps and perfumes; sometimes wood chips or resin

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

Guaiac Wood: dosing

There is no established or standardized medical dose for guaiac wood. It is most often used in small amounts as a fragrance in finished products such as soaps, perfumes, or aromatherapy diffuser blends.If you choose to use a guaiac wood product, follow the directions on the label and dilute essential oils properly before applying them to skin.

Taking Guaiac Wood and Meclofenamate Together: Common Questions

Is it safe to take Guaiac Wood with Meclofenamate?
We do not list a known interaction between Guaiac Wood and Meclofenamate. 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 Guaiac Wood and Meclofenamate 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 Guaiac Wood and Meclofenamate at the same time of day?
At least one FDA label for a product containing Meclofenamate says to take it with food. If you take Guaiac Wood on an empty stomach out of habit, keep them separate and take Meclofenamate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Meclofenamate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Guaiac Wood and Meclofenamate combination checked?
Interactions in our licensed database are recorded against drug classes. Meclofenamate is filed under 5 classifications, and Guaiac Wood has documented interactions with 1 drug class — none of Meclofenamate'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 Guaiac Wood interact with any other medications?
Yes. Guaiac Wood has 1 documented drug interaction in our database — Meclofenamate 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 Meclofenamate interact with any supplements?
Yes. Meclofenamate has documented interactions with 32 supplements in our database — Guaiac Wood is not one of them. The Meclofenamate interaction page linked on this page lists every one, ranked by severity.
