Drug & supplement interaction

Aristolochia + Fluconazole

Fluconazole brand names: Diflucan, Diflucan Injection.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Aristolochia 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. 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.

Aristolochia 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 Aristolochia 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 Fluconazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fluconazole is filed under 7 classifications — including antifungals, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Aristolochia has documented interactions with 1 drug class — the most serious being nephrotoxic drugs (moderate) — and none of Fluconazole’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.

Keep it in perspective

No Interaction Found — But Data Suggests Aristolochia and Fluconazole 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. One of them is worth acting on rather than waiting out — marked below.

See Every Supplement That Interacts With Fluconazole

This page covers Aristolochia only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Fluconazole page lists 81 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Adrafinil (moderate).

By severity: 4 major · 54 moderate · 23 minor.

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.”

About Aristolochia

What is Aristolochia?

Aristolochia
  • Promoting menstruation
  • Aphrodisiac
  • Immune stimulation
  • Snakebite remedies
  • Pain and inflammation

Aristolochia contains aristolochic acid, a potent toxin linked to severe kidney damage and cancer, and it is not safe to take. The FDA and other health authorities have warned against any product containing aristolochic acid. Despite its history in traditional medicine, no proven benefit outweighs these serious dangers.

Aristolochia spp. · Aristolochiaceae · Root, stem, and aerial parts (in traditional remedies) · Dried herb, powders, capsules, teas, and traditional tinctures

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

Aristolochia: dosing

There is no safe or recommended dose of Aristolochia. Because it contains a toxic, cancer-causing compound, it should not be taken at all.If you come across a supplement, tea, or traditional remedy that lists Aristolochia (or related names like birthwort, Mu Tong, or Fang Ji) as an ingredient, do not use it.

From our Aristolochia monograph — the full record covers uses, side effects and every documented interaction.

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.

Taking Aristolochia and Fluconazole Together: Common Questions

Is it safe to take Aristolochia with Fluconazole?
We do not list a known interaction between Aristolochia and Fluconazole. 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 Aristolochia and Fluconazole 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.
How was the Aristolochia and Fluconazole combination checked?
Interactions in our licensed database are recorded against drug classes. Fluconazole is filed under 7 classifications, and Aristolochia has documented interactions with 1 drug class — none of Fluconazole'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 Aristolochia interact with any other medications?
Yes. Aristolochia has 355 documented drug interactions in our database — Fluconazole 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 Fluconazole interact with any supplements?
Yes. Fluconazole has documented interactions with 81 supplements in our database — Aristolochia is not one of them. The Fluconazole interaction page linked on this page lists every one, ranked by severity.
