Barley + Amiloride, Hydrochlorothiazide
Amiloride, Hydrochlorothiazide brand names: Moduretic, Amilzide, Moduret 25, Amil-Co.
We found no known interaction between Barley and Amiloride, Hydrochlorothiazide 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 Amiloride, Hydrochlorothiazide 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.
Barley and Amiloride, Hydrochlorothiazide
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 Amiloride, Hydrochlorothiazide and Barley 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.
Barley safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Amiloride, Hydrochlorothiazide
Interactions in our licensed database are recorded against drug classes, not just single drug names. Amiloride, Hydrochlorothiazide is filed under 10 classifications — including potassium-sparing diuretics, thiazide diuretics, diuretic drugs. Barley has documented interactions with 1 drug class — the most serious being triclabendazole (egaten) (moderate) — and none of Amiloride, Hydrochlorothiazide’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.

Some Amiloride, Hydrochlorothiazide Products Have a Food Rule — Barley Should Not Break It
At least one FDA label for a product containing Amiloride, Hydrochlorothiazide says to take it with food. If you take Barley on an empty stomach out of habit, keep them separate — and take Amiloride, Hydrochlorothiazide 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 Amiloride, Hydrochlorothiazide 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.
DOSAGE AND ADMINISTRATION Amiloride hydrochloride and hydrochlorothiazide tablets should be administered with food.
From the Dosage and Administration section of the FDA label we read for Amiloride, Hydrochlorothiazide — 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.
What Amiloride, Hydrochlorothiazide Is Prescribed For, and What Barley Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Amiloride, Hydrochlorothiazide is a prescription medicine with approved uses on its FDA label. Barley is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Amiloride, Hydrochlorothiazide is prescribed for: Amiloride hydrochloride and hydrochlorothiazide tablets are used for patients with high blood pressure (hypertension) or congestive heart failure who tend to develop low potassium (hypokalemia) when taking a thiazide or other diuretic alone — or for whom keeping potassium levels in a normal range is especially important, such as people taking digoxin or those with significant heart rhythm problems. The tablets may be used on their own or alongside other blood pressure medicines, such as methyldopa or beta blockers. This combination product is not intended as the first-choice treatment for swelling (edema) or high blood pressure unless low potassium is a specific concern.
Barley has been studied for:
-
Hypertension studied, not established Barley has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Barley for hypertension
Although there has been interest in using oral barley for hypertension, there is insufficient reliable information about the clinical effects of barley for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Amiloride, Hydrochlorothiazide on your own; if you are taking Barley for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Amiloride, Hydrochlorothiazide page
“The typical Moduretic (amiloride with hydrochlorothiazide) patient is managing blood pressure long term, and the supplements that crowd reaches for (herbal blood pressure aids, potassium, calcium) are exactly what fills this list. It deserves a careful read, not a skim.”

About Barley
What is Barley?
- High cholesterol
- Heart health support
- Blood sugar support
- Digestive regularity and fiber
- General nutrition
Barley is a nutritious whole grain that is a good source of soluble fiber called beta-glucan, which has solid evidence for modestly lowering LDL ('bad') cholesterol when eaten regularly. It is safe as a food for most people, but those with celiac disease or gluten sensitivity should avoid it since it contains gluten. Talk to your pharmacist or doctor before using concentrated barley supplements, especially if you have a health condition.
Hordeum vulgare · Poaceae · Grain (seed), and sometimes young leaves/grass and bran · Whole grain, flour, flakes, barley bran, beta-glucan supplements, barley grass powder, tea, and capsules
An interaction check asks whether these two react with each other — it does not ask whether Barley is a good idea for someone in your situation. Here is what our Barley record says about it on its own.
Barley: dosing
There is no single official supplement dose for barley. For cholesterol benefits, research has generally used a few grams of barley beta-glucan per day, taken as part of the diet, but the exact amount can vary by product.Because products differ widely in strength and form, the best approach is to follow the directions on the product label.
