Drug & supplement interaction

Black Mulberry + Febuxostat

Febuxostat brand name: Uloric.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Black Mulberry and Febuxostat 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 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.

Black Mulberry and Febuxostat

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 Febuxostat and Black Mulberry 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.

Black Mulberry safety at a glance

Black Mulberry overall Use caution The fruit is safe as food, but concentrated supplement doses are less studied.
Pregnancy Use caution Eating the fruit as food is likely fine, but avoid concentrated extracts unless your doctor approves.
Breastfeeding Use caution Fruit as food is likely fine, but there is little safety data on supplement doses.

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

How we checked

Why No Interaction Is Listed for Febuxostat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Febuxostat is filed under 3 classifications — antigout drugs, hepatotoxic drugs, oral drugs. Black Mulberry has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and midazolam (versed) (moderate) — and none of Febuxostat’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 Black Mulberry and Febuxostat 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.

  • A skin rash reported in 4.8% of FDA reports for Febuxostat Additional detail

    “Topically, black mulberry leaf may cause contact dermatitis. A case of lichenoid contact dermatitis was reported in a 68-year-old male who came into contact with black mulberry leaves while picking black mulberries.”

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

Effects for Febuxostat come from the ADVERSE REACTIONS section of its FDA label; effects for Black Mulberry come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 16,669 voluntary FDA FAERS reports for Febuxostat 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.

From our pharmacist’s overview on the Febuxostat page

“Febuxostat (Uloric) lowers uric acid to prevent gout attacks, and because the drug itself can stress the liver, its list of 56 interacting supplements deserves real vigilance rather than a quick skim. Thirty-eight of those entries have their own record of liver harm, stacking pressure on the same organ, and two of the four major-rated…”

About Black Mulberry

What is Black Mulberry?

Black Mulberry
  • General antioxidant support
  • Blood sugar support
  • Cholesterol and heart health
  • Digestive health
  • Cold and sore throat remedies (traditional)

Black mulberry is a nutritious fruit rich in antioxidants and vitamins, and it is generally safe to enjoy as a food. Some early research on its leaf and fruit extracts hints at benefits for blood sugar and cholesterol, but the evidence is still limited. Talk with your pharmacist or doctor before using concentrated extracts, especially if you have a health condition.

Morus nigra · Moraceae · Fruit (berries), leaves, and sometimes root bark · Fresh or dried fruit, juice, jam, tea, powder, and capsules or extracts

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

Black Mulberry: dosing

There is no official standardized dose for black mulberry supplements. The amount in products varies widely depending on whether the fruit, leaf, or an extract is used.If you use a commercial product, follow the directions on the label and do not take more than recommended. Eating the fresh or dried fruit as part of a normal diet does not require special dosing.

About Febuxostat

What Is Febuxostat Used For?

Brand name: Uloric

Febuxostat (available as tablets and a dissolving oral film) is used to chronically manage hyperuricemia — high uric acid levels in the blood — in adults with gout. It is specifically for people who have not responded adequately to the highest tolerated dose of allopurinol, who cannot tolerate allopurinol, or for whom allopurinol is not appropriate.

Important limitation: febuxostat is not recommended for people who have high uric acid but no gout symptoms (asymptomatic hyperuricemia). It is also not recommended for patients whose high uric acid is caused by other conditions such as cancer treatment or Lesch-Nyhan syndrome.

Most-Reported Side Effects for Febuxostat

From FAERS, the FDA’s public side-effect reporting system (16,669 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 881 reports
Acute kidney injury 857 reports
Nausea 857 reports
Rash 800 reports
Gout 699 reports

Taking Black Mulberry and Febuxostat Together: Common Questions

Is it safe to take Black Mulberry with Febuxostat?

Do Black Mulberry and Febuxostat 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.

How was the Black Mulberry and Febuxostat combination checked?
Interactions in our licensed database are recorded against drug classes. Febuxostat is filed under 3 classifications, and Black Mulberry has documented interactions with 2 drug classes — none of Febuxostat'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 Black Mulberry interact with any other medications?
Yes. Black Mulberry has 87 documented drug interactions in our database — Febuxostat 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 Febuxostat interact with any supplements?
Yes. Febuxostat has documented interactions with 56 supplements in our database — Black Mulberry is not one of them. The Febuxostat interaction page linked on this page lists every one, ranked by severity.
