Drug & supplement interaction

Alfalfa + Uridine Triacetate

Uridine Triacetate brand names: Xuriden, Vistogard.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Alfalfa 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.

Alfalfa 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 Alfalfa 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.

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. Alfalfa has documented interactions with 6 drug classes — the most serious being warfarin (coumadin) (major), antidiabetes drugs (moderate) and contraceptive 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.

No Interaction Found — But Data Suggests Alfalfa and Uridine Triacetate May Share a Side Effect

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 reported in 15.2% of FDA reports for Uridine Triacetate Additional detail

    Alfalfa

    “Orally, flatulence and bulkier feces were reported during the first week of a case series of three subjects ingesting alfalfa. In a case series of 15 patients ingesting alfalfa, increased fecal volume and increased stool frequency was reported. Additional adverse effects included abdominal discomfort in two patients, diarrhea in two patients, loose stools in six patients, and intestinal gas in 13 patients.”

Reported for Alfalfa but not commonly for Uridine Triacetate: stomach upset, bloating or gas, low potassium and a skin rash.

Effects for Uridine Triacetate come from the ADVERSE REACTIONS section of its FDA label; effects for Alfalfa 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 — Alfalfa Should Not Break It

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

What is Alfalfa?

Alfalfa
  • High cholesterol
  • Digestive complaints
  • Menopausal symptoms
  • Arthritis and joint pain
  • General nutritional supplement

Alfalfa is a nutrient-rich legume that people use for high cholesterol, menopause symptoms, and general wellness, but solid human evidence for most of these uses is limited. It is best avoided by people with autoimmune diseases, those who are pregnant or breastfeeding, and anyone with a weakened immune system, and you should check with your pharmacist or doctor before trying it.

Medicago sativa · Fabaceae · Leaves, sprouts, and seeds · Capsules, tablets, dried leaf tea, sprouts, liquid extract, and powder

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

Alfalfa: dosing

There is no well-established standard dose for alfalfa supplements. Products vary widely in strength and form, including capsules, tablets, teas, and extracts.Because a proven safe and effective dose has not been set, the best approach is to follow the directions on the product label and not exceed the recommended amount. They can help you decide if it is appropriate for you.

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 Alfalfa and Uridine Triacetate Together: Common Questions

Is it safe to take Alfalfa with Uridine Triacetate?
We do not list a known interaction between Alfalfa 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 Alfalfa and Uridine Triacetate have any of the same side effects?
Yes — our sources link each of them separately to one 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 Alfalfa 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 Alfalfa 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 Alfalfa and Uridine Triacetate combination checked?
Interactions in our licensed database are recorded against drug classes. Uridine Triacetate is filed under 1 classification, and Alfalfa 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 Alfalfa interact with any other medications?
Yes. Alfalfa has 583 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 — Alfalfa is not one of them. The Uridine Triacetate interaction page linked on this page lists every one, ranked by severity.
