Clay + Uridine Triacetate
Uridine Triacetate brand names: Xuriden, Vistogard.
We found no known interaction between Clay 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.
Clay 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 Clay 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.
Clay safety at a glance
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.
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. Clay has documented interactions with 2 drug classes — the most serious being cimetidine (tagamet) (moderate) and quinine (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.
Clay Does Interact With Other Medications
Clay has 3 moderate known drug interactions in our database — Uridine Triacetate isn’t one of them. If you take anything else, check it against the full list below.

Clay in Pregnancy & Breastfeeding
When used orally, long-term. Clay ingestion during pregnancy appears to be associated with an increased incidence of pre-eclampsia, hypertension, and/or edema. There is insufficient reliable information available about the safety of ingesting clay short-term during pregnancy.

Some Uridine Triacetate Products Have a Food Rule — Clay Should Not Break It
At least one FDA label for a product containing Uridine Triacetate says to take it with food. If you take Clay 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.
See Every Supplement That Interacts With Uridine Triacetate
This page covers Clay 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 Clay
What is Clay?
- Detox and digestive complaints
- Skin care (masks, acne, irritation)
- Diarrhea and upset stomach
- Drawing out toxins or impurities
- Wound and rash poultices
Clay is a fine, mineral-rich earth (such as bentonite or kaolin) used on the skin and sometimes taken by mouth for digestive and 'detox' purposes. Topical use for masks and minor skin issues is popular and generally low-risk, but swallowing clay carries real safety concerns, including possible contamination with lead and other heavy metals. Talk to a pharmacist or doctor before taking clay internally.
Mineral-rich clay (bentonite, kaolin, French green clay, and similar) · Powder, capsules, masks, poultices, suspensions/drinks
An interaction check asks whether these two react with each other — it does not ask whether Clay is a good idea for someone in your situation. Here is what our Clay record says about it on its own.
Clay: dosing
There is no well-established, standardized dose for clay, and no recommended safe amount for eating it. Because of contamination and absorption concerns, taking clay internally is generally not recommended without medical guidance.If you use a topical product, follow the label directions for how long to leave a mask on and how often to use it. Choose products that are independently tested for heavy metals.

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.
