We found no known interaction between Water Avens and Fluconazole in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Water Avens and Fluconazole

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 Fluconazole and Water Avens 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 Water Avens at all — not against Fluconazole, 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 Fluconazole’s Own FDA Label Lists

This is not an interaction — none of it involves Water Avens. These are the most notable effects listed in the ADVERSE REACTIONS section of Fluconazole’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Low potassium Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • An irregular heartbeat Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • A low platelet count Worth acting on
  • A severe allergic reaction Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Fluconazole. Read the label on DailyMed › Water Avens’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Water Avens side to compare — that is a limit of the record, not a statement that Water Avens has no side effects.

From our pharmacist’s overview on the Fluconazole page

“Fluconazole (Diflucan) treats fungal infections, and I would pair it with supplements carefully. Nearly half of the 81 ingredients with an interaction on file, 38 of them, put extra strain on the liver, which is already busy processing the antifungal.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Water Avens is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Water Avens reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Water Avens and Fluconazole records this page draws on were last updated July 11, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Water Avens

What is Water Avens?

  • Diarrhea and digestive upset
  • Sore throat and mouth irritation
  • Mild fever
  • General tonic
  • Astringent for minor wounds

Water avens is a traditional herb whose root has been used as an astringent for diarrhea, sore throats, and digestive complaints. There is very little modern scientific research to confirm that it works or to define a safe dose, so use it cautiously and talk with a pharmacist or doctor first.

Geum rivale · Rosaceae · Root and rhizome (occasionally aerial parts) · Dried root, tea/decoction, tincture

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

Water Avens: dosing

There is no established or standardized dose for water avens. Traditional use involved teas (decoctions) of the dried root or tinctures, but reliable, research-based dosing is not available.If you choose to use a product, follow the directions on the label and do not exceed them.

About Fluconazole

What Is Fluconazole Used For?

Brand names: Diflucan, Diflucan Injection

Fluconazole treats infections caused by Candida and Cryptococcus fungi. Diflucan tablets and oral fluconazole tablets and suspension are approved to treat vaginal yeast infections (vaginal candidiasis), thrush in the mouth or throat (oropharyngeal candidiasis), and yeast infections of the esophagus. All forms — tablets, oral suspension, and injection — are used for cryptococcal meningitis (a serious fungal brain infection). In smaller studies, fluconazole has also shown effectiveness against Candida urinary tract infections, peritonitis (infection in the abdomen), and serious systemic (bloodstream and organ) Candida infections.

Fluconazole is also used to prevent candidiasis in people undergoing bone marrow transplants who receive chemotherapy or radiation therapy. Note that vaginal candidiasis is an approved use for the tablets and Diflucan oral products, but not for the injection or oral suspension alone.

Most-Reported Side Effects for Fluconazole
