Drug & supplement interaction

Pumpkin + Amiloride, Hydrochlorothiazide

Amiloride, Hydrochlorothiazide brand names: Moduretic, Amilzide, Moduret 25, Amil-Co.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Pumpkin 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.

Pumpkin 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 Pumpkin 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 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. Pumpkin has documented interactions with 1 drug class — the most serious being lithium (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.

What to actually watch for

No Interaction Found — But Data Suggests Pumpkin and Amiloride, Hydrochlorothiazide 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. 3 of them are worth acting on rather than waiting out — marked below.

  • Shortness of breath / Hives / An allergic reaction Worth acting on Additional detail

    Pumpkin

    “Orally, pumpkin seed oil and pumpkin pulp have been reported to cause anaphylactic reactions in children and adults. A case review highlights 4 cases of anaphylaxis in children (3 from pumpkin pulp, 1 from pumpkin seeds), and 7 cases in adults (1 from pumpkin flesh, 6 from pumpkin seeds).”

How to take them

Some Amiloride, Hydrochlorothiazide Products Have a Food Rule — Pumpkin Should Not Break It

At least one FDA label for a product containing Amiloride, Hydrochlorothiazide says to take it with food. If you take Pumpkin 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.

About Pumpkin

What is Pumpkin?

Pumpkin
  • Benign prostatic hyperplasia (BPH) symptoms
  • Overactive bladder
  • Eye and skin health (vitamin A source)
  • General nutrition and fiber
  • Hair health

Pumpkin is a nutritious squash, and its seeds and seed oil are the parts most often used as supplements, mainly for urinary and prostate symptoms. The evidence for these uses is limited and mostly preliminary, though eating pumpkin as a food is safe and a good source of vitamin A, fiber, and antioxidants. Talk to your pharmacist or doctor before using concentrated pumpkin seed supplements.

Cucurbita pepo · Cucurbitaceae · Fruit flesh, seeds, and seed oil · Whole food, capsules, softgels (seed oil), powders, raw or roasted seeds

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

Pumpkin: dosing

There is no official standardized dose for pumpkin supplements. Studies have used different forms and amounts of seed or seed oil, so it is hard to recommend one exact dose.The best approach is to follow the directions on the product label and not exceed the recommended amount.

About Amiloride and Hydrochlorothiazide

What Is Amiloride and Hydrochlorothiazide Used For?

Brand names: Moduretic, Amilzide, Moduret 25, Amil-Co

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.

Taking Pumpkin and Amiloride, Hydrochlorothiazide Together: Common Questions

Is it safe to take Pumpkin with Amiloride, Hydrochlorothiazide?
