Drug & supplement interaction

Rutin + Fluconazole

Fluconazole brand names: Diflucan, Diflucan Injection.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Rutin 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.

Rutin 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 Rutin 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. Rutin has documented interactions with 1 drug class — the most serious being antidiabetes 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.

No Interaction Found — But Data Suggests Rutin 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.

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 Rutin

What is Rutin?

  • Varicose veins and chronic venous insufficiency
  • Hemorrhoids
  • Easy bruising and fragile capillaries
  • Swelling (edema) in the legs
  • General antioxidant support

Rutin is a plant flavonoid (often taken from buckwheat or citrus) that people use mainly for blood vessel and circulation problems like varicose veins and hemorrhoids. The evidence is limited and mostly preliminary, so it should not replace proven treatments. It is generally well tolerated, but talk to your pharmacist or doctor before starting it, especially if you are pregnant or breastfeeding.

A flavonoid found in many plants, such as buckwheat, citrus fruits, apples, and tea · Tablets, capsules, powders, and combination supplements (sometimes with vitamin C or other bioflavonoids)

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

Rutin: dosing

There is no official, standardized dose of rutin. Different products contain different amounts, and rutin is often combined with other ingredients.Because a proven safe and effective dose has not been clearly established, the best approach is to follow the directions on the product label and not take more than recommended.

From our Rutin 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.

Most-Reported Side Effects for Fluconazole

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Rutin and Fluconazole Together: Common Questions

Is it safe to take Rutin with Fluconazole?
We do not list a known interaction between Rutin 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 Rutin 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 Rutin and Fluconazole combination checked?
Interactions in our licensed database are recorded against drug classes. Fluconazole is filed under 7 classifications, and Rutin 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 Rutin interact with any other medications?
Yes. Rutin has 86 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 — Rutin is not one of them. The Fluconazole interaction page linked on this page lists every one, ranked by severity.
