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

We found no known interaction between Rosemary 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.

Rosemary 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 Rosemary 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.

Rosemary safety at a glance

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. Rosemary has documented interactions with 6 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and aspirin (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 Rosemary Itself Has Been Linked To

This is not an interaction — nothing below involves Uridine Triacetate. It is the side-effect record for Rosemary on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Rosemary, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Wheezing / An allergic reaction Worth acting on Additional detail

    “Topically, allergic reactions can occur. When used in the mouth, lip and gum edema have occurred. When used on the skin, allergic contact dermatitis has occurred, likely due to the constituent carnosol.

    Rosemary might also cause occupational asthma. A case of occupational asthma caused by several aromatic herbs including thyme, rosemary, bay leaf, and garlic has been reported.”

Everything above comes from the Natural Medicines adverse-effect record for Rosemary — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Uridine Triacetate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Uridine Triacetate column appears here.

Rosemary in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally in medicinal amounts. Rosemary might have uterine and menstrual flow stimulant effects, and might increase metabolism of estradiol and estrone; avoid using. There is insufficient reliable information available about the safety of rosemary when used topically during pregnancy.

How to take them

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

At least one FDA label for a product containing Uridine Triacetate says to take it with food. If you take Rosemary 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. See the Uridine Triacetate drug page ›

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.

Everything else you take

See Every Supplement That Interacts With Uridine Triacetate

This page covers Rosemary only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Uridine Triacetate page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

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 Rosemary

What is Rosemary?

Rosemary
  • Memory and concentration
  • Digestive upset
  • Hair growth
  • Anxiety and stress (aromatherapy)
  • Muscle and joint discomfort
  • Antioxidant support

Rosemary is a fragrant Mediterranean herb that is safe and flavorful in normal food amounts. Some early research suggests possible benefits for memory, mood, and hair growth, but the evidence is limited and far from conclusive. Concentrated supplements and the essential oil should be used carefully, and the essential oil should never be swallowed.

Rosmarinus officinalis · Lamiaceae · Leaves and essential oil · Culinary herb, tea, capsules, dried leaf extract, essential oil (for aromatherapy and topical use)

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

Rosemary: dosing

There is no well-established standardized dose for rosemary as a supplement. Amounts used in studies have varied widely depending on the form (tea, extract, or aromatherapy).If you use a rosemary supplement, follow the directions on the product label and do not exceed the recommended amount.

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 Rosemary and Uridine Triacetate Together: Common Questions

Is it safe to take Rosemary with Uridine Triacetate?
We do not list a known interaction between Rosemary 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 Rosemary 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 Rosemary 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 Rosemary and Uridine Triacetate combination checked?
Interactions in our licensed database are recorded against drug classes. Uridine Triacetate is filed under 1 classification, and Rosemary has documented interactions with 6 drug classes — 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 Rosemary interact with any other medications?
Yes. Rosemary has 372 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 — Rosemary is not one of them. The Uridine Triacetate interaction page linked on this page lists every one, ranked by severity.
