Drug & supplement interaction

L-ornithine-l-aspartate + Rotigotine

Rotigotine brand name: Neupro.

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 L-ornithine-l-aspartate and Rotigotine 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.

L-ornithine-l-aspartate and Rotigotine

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 Rotigotine 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 Rotigotine, 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.

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

See Every Supplement That Interacts With Rotigotine

This page covers L-ornithine-l-aspartate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Rotigotine page lists 7 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Ayahuasca (moderate), Black Horehound (moderate), Dimethylsulfoxide (dmso) (moderate), Syrian Rue (moderate) and Turpentine Oil (moderate).

By severity: 6 moderate · 1 minor.

From our pharmacist’s overview on the Rotigotine page

“Rotigotine (Neupro) treats Parkinson's disease and restless legs through a skin patch, and the seven supplement interactions on file split along those two facts. None rates major, six are moderate and one minor, so this reads as a watch list rather than a stop list.”

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 Rotigotine Together: Common Questions

Is it safe to take L-ornithine-l-aspartate with Rotigotine?
We do not list a known interaction between L-ornithine-l-aspartate and Rotigotine. 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 Rotigotine have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
Does Rotigotine interact with any supplements?
Yes. Rotigotine has documented interactions with 7 supplements in our database — L-ornithine-l-aspartate is not one of them. The Rotigotine interaction page linked on this page lists every one, ranked by severity.
