The bottom line No known interaction

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

L-ornithine-l-aspartate and Palifermin

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 Palifermin 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 Palifermin, 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.

We read the ADVERSE REACTIONS section of Palifermin’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Palifermin column appears here.

From our pharmacist’s overview on the Palifermin page

“Palifermin (Kepivance) is given by IV to prevent the severe mouth sores that intensive chemotherapy can cause, most often in patients heading into a stem cell transplant, and I read its interaction list with genuine caution because of how fragile those patients already are. All 17 supplements on file act on absorption through the gut,…”

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.

About Palifermin

What Is Palifermin Used For?

Brand name: Kepivance

Kepivance (palifermin) is used to decrease how often and how long severe oral mucositis — painful sores in the mouth and throat — occurs in patients with hematologic malignancies (blood cancers such as lymphoma, leukemia, or multiple myeloma) who are receiving high-dose, cell-damaging (myelotoxic) therapy before an autologous hematopoietic stem cell transplant (a transplant using the patient's own stem cells).

Kepivance is specifically indicated when the preparative chemotherapy or radiation regimen is expected to cause severe mucositis in most patients. It is not recommended for use with a high-dose melphalan conditioning regimen, and it was not found to be effective in the setting of allogeneic stem cell transplant (using a donor's cells). Its safety and effectiveness have not been established for patients with non-blood cancers (non-hematologic malignancies).

Most-Reported Side Effects for Palifermin

From FAERS, the FDA’s public side-effect reporting system (388 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Mucosal inflammation 56 reports
Febrile neutropenia 39 reports
Rash 39 reports
Stomatitis 34 reports
Erythema 28 reports
