Drug & supplement interaction

Cannabis + Amiloride, Hydrochlorothiazide

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

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

We found no known interaction between Cannabis 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.

Cannabis 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 Cannabis 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. Cannabis has documented interactions with 18 drug classes — the most serious being warfarin (coumadin) (major), alcohol (ethanol) (moderate) and anesthesia (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.

Keep it in perspective

No Interaction Found — But Data Suggests Cannabis 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. 10 of them are worth acting on rather than waiting out — marked below.

Cannabis in Pregnancy & Breastfeeding

Lactation Likely Unsafe

When used orally or inhaled. Delta-9-tetrahydrocannabinol (THC) is concentrated and excreted in breast milk for longer than 6 weeks after cessation of cannabis use. Prolonged cannabis use during lactation has been associated with delayed motor development. Observational research in mothers who successfully abstained from cannabis use for 6 weeks (confirmed by a negative THC urine screen) after smoking cannabis prenatally at least twice weekly, found that THC levels in breastmilk increased during the first 2 weeks of abstinence and then decreased but remained detectable at 6 weeks. For patients planning to breastfeed, recommend abstaining from cannabis use prenatally and during lactation. Recommendations to discard breastmilk until THC levels are undetectable are not practical, as this may take more than 6 weeks. According to the American College of Obstetrics and Gynecology, cannabis use during lactation is discouraged due to limited long-term safety data in infants.

How to take them

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

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

What is Cannabis?

Cannabis
  • Chronic pain
  • Nausea and vomiting from chemotherapy
  • Muscle spasticity (e.g., multiple sclerosis)
  • Anxiety and stress
  • Sleep problems
  • Appetite stimulation

Cannabis contains many active compounds, mainly THC (which causes a 'high') and CBD (which does not). Some uses, such as chemotherapy-related nausea, certain seizure disorders, and muscle spasticity, have meaningful evidence, while many other popular uses are not well proven. It can cause real side effects and impairment, so talk to your doctor or pharmacist and follow your local laws before using it.

Cannabis sativa · Cannabaceae · Dried flowers (buds), leaves, and extracted resins/oils · Dried flower for smoking or vaporizing, edibles, oils and tinctures, capsules, topical creams, prescription products (e.g., dronabinol, nabilone, cannabidiol)

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

Cannabis: dosing

There is no single standard dose for cannabis. The right amount depends on the product, its strength, the THC and CBD content, how it is taken, and the person using it. Products can vary a lot in potency, which makes consistent dosing difficult.A common harm-reduction approach is to 'start low and go slow,' meaning begin with a small amount and wait to see how it affects you before taking more. This is especially important with edibles, which can take an hour or more to work.For prescription cannabis-based medicines, follow your doctor's instructions exactly.

Taking Cannabis and Amiloride, Hydrochlorothiazide Together: Common Questions

Is it safe to take Cannabis with Amiloride, Hydrochlorothiazide?
We do not list a known interaction between Cannabis and Amiloride, Hydrochlorothiazide. 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 Cannabis and Amiloride, Hydrochlorothiazide have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Cannabis and Amiloride, Hydrochlorothiazide at the same time of day?
At least one FDA label for a product containing Amiloride, Hydrochlorothiazide says to take it with food. If you take Cannabis on an empty stomach out of habit, keep them separate and take Amiloride, Hydrochlorothiazide with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Amiloride, Hydrochlorothiazide products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Cannabis and Amiloride, Hydrochlorothiazide combination checked?
Interactions in our licensed database are recorded against drug classes. Amiloride, Hydrochlorothiazide is filed under 10 classifications, and Cannabis has documented interactions with 18 drug classes — none of Amiloride, Hydrochlorothiazide'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 Cannabis interact with any other medications?
Yes. Cannabis has 1,137 documented drug interactions in our database — Amiloride, Hydrochlorothiazide 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 Amiloride, Hydrochlorothiazide interact with any supplements?
Yes. Amiloride, Hydrochlorothiazide has documented interactions with 236 supplements in our database — Cannabis is not one of them. The Amiloride, Hydrochlorothiazide interaction page linked on this page lists every one, ranked by severity.
