The bottom line No known interaction

We found no known interaction between Arrowroot and Probenecid 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.

Arrowroot and Probenecid

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 Probenecid and Arrowroot 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Arrowroot at all — not against Probenecid, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Arrowroot Itself Has Been Linked To

This is not an interaction — nothing below involves Probenecid. It is the side-effect record for Arrowroot on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Arrowroot, this list is the first place to look.

  • Stomach upset / Constipation Additional detail

    “Orally, arrowroot starch from the root or rhizome is well tolerated when used in the amounts found in foods (12). There is a limited amount of information available about the adverse effects of arrowroot when used in medicinal amounts. In one clinical trial, it was reported to cause dyspepsia, constipation, and dark stools (12,32448).”

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

From our pharmacist’s overview on the Probenecid page

“Probenecid does its work through the kidneys, pulling uric acid out of the blood to control gout, and that is exactly why the 30 supplement and herbal interactions on file deserve genuine care rather than a quick skim. The three rated major strike where this drug is most vulnerable: two are herbs, Siberian cocklebur among them, that ca…”

About Arrowroot

What is Arrowroot?

Arrowroot
  • Diarrhea
  • Irritable bowel syndrome (IBS) symptoms
  • Digestive upset
  • Gluten-free thickener/food ingredient
  • Soothing skin and cosmetics

Arrowroot is a starch made from the roots of Maranta arundinacea and is mainly used as a gentle, easy-to-digest thickening agent in food. Some people use it for diarrhea and digestive discomfort, but solid human evidence for these health benefits is limited. As a food it is generally well tolerated, but talk with your pharmacist or doctor before using it to treat a medical condition.

Maranta arundinacea · Marantaceae · Rhizomes (roots), processed into starch · Powder (starch), flour, capsules, food thickener, cosmetic ingredient

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

Arrowroot: dosing

There is no official or standardized medicinal dose for arrowroot. In cooking, it is used in small amounts as a thickener, and there is no established "therapeutic" dose proven to treat any condition.If you are using a packaged arrowroot product or supplement, follow the directions on the label.

About Probenecid

What Is Probenecid Used For?

Brand names: Benemid, Benuryl, Probecid

Probenecid tablets are used to treat hyperuricemia (high uric acid levels in the blood) associated with gout and gouty arthritis. By helping the kidneys remove more uric acid, it lowers uric acid levels over time and helps prevent painful gout attacks.

Probenecid tablets are also used alongside certain penicillin-type antibiotics — including penicillin, ampicillin, methicillin, oxacillin, cloxacillin, and nafcillin — to raise and sustain the antibiotic's level in the bloodstream, making the antibiotic work more effectively.
