No Known Interaction
Medically reviewed by · Updated June 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Oleic Acid and Uridine Triacetate 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 Uridine Triacetate states a food rule worth keeping to.

Interaction report

Oleic Acid and Uridine Triacetate

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 Uridine Triacetate and Oleic Acid 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.

Oleic Acid safety at a glance

Oleic Acid overall Generally safe Generally recognized as safe when consumed in normal amounts from foods like olive oil.
Pregnancy Use caution Amounts found in foods are fine, but concentrated supplements are not well studied in pregnancy.
Breastfeeding Use caution Food amounts are considered safe, but supplement-level doses lack good safety data.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Uridine Triacetate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Uridine Triacetate is filed under a single classification — oral drugs. Oleic Acid has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Uridine Triacetate’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

What to actually watch for

What Uridine Triacetate’s Own FDA Label Lists

This is not an interaction — none of it involves Oleic Acid. These are the most notable effects listed in the ADVERSE REACTIONS section of Uridine Triacetate’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Diarrhea mentioned in 15.2% of FDA reports for Uridine Triacetate
  • Vomiting mentioned in 15.2% of FDA reports for Uridine Triacetate
  • Nausea mentioned in 8.7% of FDA reports for Uridine Triacetate

From the ADVERSE REACTIONS section of the FDA label for Uridine Triacetate. Read the label on DailyMed › Where a percentage is shown, it is the share of 138 voluntary FDA FAERS reports for Uridine Triacetate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Oleic Acid’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Oleic Acid side to compare — that is a limit of the record, not a statement that Oleic Acid has no side effects.

How to take them

Some Uridine Triacetate Products Have a Food Rule — Oleic Acid Should Not Break It

At least one FDA label for a product containing Uridine Triacetate says to take it with food. If you take Oleic Acid on an empty stomach out of habit, keep them separate — and take Uridine Triacetate 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 Uridine Triacetate 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.

Administer the dose with food (applesauce, pudding or yogurt) or in milk or infant formula.

From the Dosage and Administration section of the FDA label we read for Uridine Triacetate — 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.

From our pharmacist’s overview on the Uridine Triacetate page

“Uridine triacetate is a drug you take when absorption truly cannot fail, whether as Vistogard, the emergency antidote for fluorouracil or capecitabine overdose, or as Xuriden for hereditary orotic aciduria. That is why the 17 supplement interactions on file deserve real care rather than a shrug.”

About Oleic Acid

What is Oleic Acid?

  • Heart health
  • Healthy cooking fat
  • Skin moisturizing
  • Part of the Mediterranean diet
  • Anti-inflammatory support

Oleic acid is a heart-healthy monounsaturated fat found mainly in olive oil, canola oil, avocados, and nuts. As part of a Mediterranean-style diet, it is widely viewed as a healthier replacement for saturated fats, but it is still a calorie-dense fat, so amounts matter. Talk to your pharmacist or doctor before using concentrated supplements.

Fatty acid found in plant oils and animal fats · Olive oil, capsules, softgels, cooking oils, skin products

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

Oleic Acid: dosing

There is no official standardized dose of oleic acid as a supplement. Most people get healthy amounts simply by using olive oil and eating foods like nuts and avocados in place of less healthy fats.If you use an oleic acid product or olive oil supplement, follow the directions on the product label. Because it is a fat with calories, keep portion sizes reasonable.

About Uridine Triacetate

What Is Uridine Triacetate Used For?

Brand names: Xuriden, Vistogard

Uridine triacetate is available as two different products for two distinct uses. Vistogard is used for emergency treatment after an overdose of the chemotherapy drugs fluorouracil or capecitabine — or when someone develops severe, early, or life-threatening side effects from those drugs (such as heart or nervous system problems, severe digestive reactions, or a dangerous drop in white blood cells) within 96 hours of their last dose.

Xuriden is used to treat hereditary orotic aciduria, a rare inherited condition in which the body cannot make enough of a building block called uridine, causing a buildup of orotic acid and problems with blood cell production and other body functions. Both products are approved for adults and children.

Taking Oleic Acid and Uridine Triacetate Together: Common Questions

Is it safe to take Oleic Acid with Uridine Triacetate?
We do not list a known interaction between Oleic Acid and Uridine Triacetate. 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.
Should I take Oleic Acid and Uridine Triacetate at the same time of day?
At least one FDA label for a product containing Uridine Triacetate says to take it with food. If you take Oleic Acid on an empty stomach out of habit, keep them separate and take Uridine Triacetate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Uridine Triacetate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Oleic Acid and Uridine Triacetate combination checked?
Interactions in our licensed database are recorded against drug classes. Uridine Triacetate is filed under 1 classification, and Oleic Acid has documented interactions with 1 drug class — none of Uridine Triacetate'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 Oleic Acid interact with any other medications?
Yes. Oleic Acid has 86 documented drug interactions in our database — Uridine Triacetate 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 Uridine Triacetate interact with any supplements?
Yes. Uridine Triacetate has documented interactions with 17 supplements in our database — Oleic Acid is not one of them. The Uridine Triacetate interaction page linked on this page lists every one, ranked by severity.
