Drug & supplement interaction

Tribulus + Uridine Triacetate

Uridine Triacetate brand names: Xuriden, Vistogard.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Tribulus 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, and 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

Tribulus 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 Tribulus 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.

Tribulus safety at a glance

Tribulus overall Use caution Often well tolerated short-term in healthy adults, but quality and long-term safety data are limited.

Pregnancy Possibly Unsafe When used orally. Animal research suggests that tribulus might adversely affect fetal development; avoid using. Read the full pregnancy detail

Breastfeeding Avoid Avoid while breastfeeding due to a lack of reliable safety information.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. 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. Tribulus has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and lithium (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

No Interaction Found — But Data Suggests Tribulus and Uridine Triacetate 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 / Vomiting / Nausea reported in 15.2% of FDA reports for Uridine Triacetate Additional detail
Tribulus
“Orally, tribulus can cause abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation. However, in one study, the rates of these gastrointestinal complaints were similar for patients taking tribulus and those receiving placebo.”

Listed in the ADVERSE REACTIONS section of the FDA label for Uridine Triacetate, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Tribulus but not commonly for Uridine Triacetate: kidney problems, stomach pain, constipation and liver problems.

Effects for Uridine Triacetate come from the ADVERSE REACTIONS section of its FDA label; effects for Tribulus come from the Natural Medicines adverse-effect record, quoted above. 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. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

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

At least one FDA label for a product containing Uridine Triacetate says to take it with food. If you take Tribulus 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.

Everything else you take

See Every Supplement That Interacts With Uridine Triacetate

This page covers Tribulus 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 Tribulus

What is Tribulus?

Low libido and sexual function
Athletic performance and muscle building
Testosterone support
Male and female fertility
General 'vitality' or wellness

Tribulus is a plant supplement most often marketed to boost libido, testosterone, and athletic performance, but the human evidence behind these claims is weak and inconsistent. It is generally well tolerated by healthy adults in the short term, but it should be avoided during pregnancy and breastfeeding and discussed with your pharmacist or doctor before use.

Tribulus terrestris · Zygophyllaceae · Fruit, leaf, and root · Capsules, tablets, powders, tinctures, and standardized extracts

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

Tribulus: dosing

There is no well-established standard dose for Tribulus. Studies have used a range of doses and different extracts, often standardized to a percentage of saponins, which makes it hard to compare products or recommend one amount.The best approach is to follow the directions on the specific product label and not exceed them.

Medication

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 Tribulus and Uridine Triacetate Together: Common Questions

Is it safe to take Tribulus with Uridine Triacetate?

We do not list a known interaction between Tribulus 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.

Do Tribulus and Uridine Triacetate 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.

Should I take Tribulus 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 Tribulus 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 Tribulus and Uridine Triacetate combination checked?

Interactions in our licensed database are recorded against drug classes. Uridine Triacetate is filed under 1 classification, and Tribulus has documented interactions with 3 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 Tribulus interact with any other medications?

Yes. Tribulus has 259 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 — Tribulus is not one of them. The Uridine Triacetate interaction page linked on this page lists every one, ranked by severity.
