No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Guaiac Wood and Indapamide 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.

Interaction report

Guaiac Wood and Indapamide

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 Indapamide 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 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 Indapamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Indapamide is filed under 5 classifications — including thiazide diuretics, diuretic drugs, qt interval-prolonging drugs. Guaiac Wood has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Indapamide’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 Indapamide 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.

  • Diarrhea reported in 4.9% of FDA reports for Indapamide Additional detail

Where a percentage is shown, it is the share of 17,821 voluntary FDA FAERS reports for Indapamide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it.

From our pharmacist’s overview on the Indapamide page

“A water pill like indapamide (Lozol) lowers blood pressure and pulls potassium down, and most of the 215 supplements and herbs on file press on those same levers. Thirteen entries rate major, so this is a list to read with real care rather than skim.”

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.

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.

About Indapamide

What Is Indapamide Used For?

Brand names: Lozol, Lozide

Indapamide tablets are used to treat high blood pressure (hypertension), either on their own or together with other blood pressure medications. Lowering blood pressure helps reduce the risk of related complications.

Indapamide tablets are also used to treat salt and fluid retention (edema) associated with congestive heart failure. In certain cases, indapamide may also be appropriate during pregnancy when swelling is caused by a medical condition rather than normal pregnancy changes — but routine use in otherwise healthy pregnant women is not recommended.

Most-Reported Side Effects for Indapamide

From FAERS, the FDA’s public side-effect reporting system (17,821 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hyponatraemia 1,318 reports
Acute kidney injury 949 reports
Dyspnea 920 reports
Dizziness 899 reports
