L-ornithine-l-aspartate + Triamterene

Triamterene brand name: Dyrenium.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between L-ornithine-l-aspartate and Triamterene 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

L-ornithine-l-aspartate and Triamterene

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 Triamterene and L-ornithine-l-aspartate 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.

Worth understanding: our licensed dataset holds no drug-interaction record for L-ornithine-l-aspartate at all — not against Triamterene, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

No Interaction Found — But Data Suggests L-ornithine-l-aspartate and Triamterene 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.

  • Diarrhea reported in 5.3% of FDA reports for Triamterene Additional detail

Reported for L-ornithine-l-aspartate but not commonly for Triamterene: muscle pain and cough.

Effects for Triamterene come from the ADVERSE REACTIONS section of its FDA label; effects for L-ornithine-l-aspartate come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 13,176 voluntary FDA FAERS reports for Triamterene that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Triamterene Is Prescribed For, and What L-ornithine-l-aspartate Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Triamterene is a prescription medicine with approved uses on its FDA label. L-ornithine-l-aspartate is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Triamterene is prescribed for: Triamterene treats edema (fluid buildup and swelling) linked to several conditions. These include heart failure, cirrhosis of the liver, and nephrotic syndrome (a kidney condition). It also treats steroid-induced edema, idiopathic edema (swelling with no clear cause), and edema from secondary hyperaldosteronism (high levels of the hormone aldosterone caused by another condition). It can be used alone or with other diuretics, for extra water-removing effect or to help the body hold on to potassium.

Read the rest of what Triamterene is prescribed for

It can also help when other diuretics, such as thiazides, have not worked well enough because of secondary hyperaldosteronism. Dyrenium and triamterene capsules carry the same uses.

L-ornithine-l-aspartate has been studied for:

  • Cirrhosis studied, not established L-ornithine-l-aspartate has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    L-ornithine-l-aspartate for cirrhosis

    It is unclear if oral or intravenous L-ornithine-L-aspartate can reduce complications in adults with cirrhosis.

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 Triamterene on your own; if you are taking L-ornithine-l-aspartate for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Asarabacca (major) and Siberian Cocklebur (major).

By severity: 6 major · 136 moderate · 23 minor.

From our pharmacist’s overview on the Triamterene page

“Because triamterene (Dyrenium) both lowers blood pressure and hangs onto potassium, its supplement list calls for real vigilance. Six of the 165 ingredients on file carry a major rating, and those six deserve your attention before any others.”

About L-ornithine-l-aspartate

What is L-ornithine-l-aspartate?

L-ornithine-l-aspartate
  • Liver-related brain symptoms (hepatic encephalopathy)
  • Lowering blood ammonia levels
  • Support in cirrhosis and fatty liver
  • General liver support

L-ornithine-L-aspartate (LOLA) is a combination of two amino acids studied mainly for lowering ammonia in people with liver disease and helping manage hepatic encephalopathy. There is reasonable clinical evidence for this specific medical use, but it should be used under medical supervision rather than as a casual 'liver detox' supplement. Talk to your doctor or pharmacist before using it, especially if you have liver or kidney problems.

Oral granules/powder, tablets, oral solution, and intravenous infusion (in clinical settings)

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

L-ornithine-l-aspartate: dosing

There is no single standardized over-the-counter dose for L-ornithine-L-aspartate, and the amounts used in studies were often given in a hospital or clinical setting. Oral and IV forms are dosed differently, and the right amount depends on the condition being treated.If you are using a supplement product, follow the directions on the label and do not exceed them.

Taking L-ornithine-l-aspartate and Triamterene Together: Common Questions

Is it safe to take L-ornithine-l-aspartate with Triamterene?
We do not list a known interaction between L-ornithine-l-aspartate and Triamterene. 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 L-ornithine-l-aspartate and Triamterene have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Are L-ornithine-l-aspartate and Triamterene used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for L-ornithine-l-aspartate in each. That is a conversation for your prescriber, especially if Triamterene is being adjusted to a target.
Does Triamterene interact with any supplements?
Yes. Triamterene has documented interactions with 165 supplements in our database — L-ornithine-l-aspartate is not one of them. The Triamterene interaction page linked on this page lists every one, ranked by severity.
