Drug & supplement interaction

Yogurt + Fluconazole

Fluconazole brand names: Diflucan, Diflucan Injection.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Yogurt 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.

Yogurt 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 Yogurt 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. Yogurt has documented interactions with 3 drug classes — the most serious being ciprofloxacin (cipro) (moderate), tetracycline antibiotics (moderate) and nilotinib (tasigna) (minor) — 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 Yogurt and Fluconazole May Share Several of the Same Side Effects

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.

Overlapping uses

What Fluconazole Is Prescribed For, and What Yogurt Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Fluconazole is a prescription medicine with approved uses on its FDA label. Yogurt is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Fluconazole is prescribed for: 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.

Read the rest of what Fluconazole is prescribed for

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.

Yogurt has been studied for:

  • Vaginal candidiasis studied, not established Yogurt has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Yogurt for vaginal candidiasis

    Intravaginal yogurt has only been evaluated in combination with other ingredients; its benefits when used alone are unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Fluconazole on your own; if you are taking Yogurt for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Fluconazole

This page covers Yogurt 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 Yogurt

What is Yogurt?

  • Digestive health
  • Restoring gut bacteria after antibiotics
  • Vaginal yeast or bacterial balance
  • Source of protein and calcium
  • General immune and gut support

Yogurt is a fermented dairy food that often contains live bacteria (probiotics) and provides protein, calcium, and other nutrients. For most healthy people it is a safe, nutritious food, and some yogurts with live cultures may help with digestion and gut balance, though evidence varies by strain and condition. If you are lactose intolerant, have a milk allergy, or have a weakened immune system, talk to your pharmacist or doctor first.

Fermented milk product (made with live bacterial cultures) · Plain yogurt, Greek yogurt, drinkable yogurt (kefir-style), probiotic yogurt, dairy-free yogurt alternatives

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

Yogurt: dosing

There is no official "dose" for yogurt because it is a food, not a standardized medicine. The amount and type of live bacteria can vary widely from product to product, and many people simply eat one or more servings a day as part of a healthy diet.If you are using yogurt specifically for its probiotic content, look for a label that says "live and active cultures" and check whether the strains are listed. There is no proven "best" amount for any health condition. If you want a specific probiotic strain or dose, a standardized probiotic supplement may be more reliable.

Pharmacist Counseling Corner

Taking Yogurt and Fluconazole Together: Common Questions

Is it safe to take Yogurt with Fluconazole?
We do not list a known interaction between Yogurt 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 Yogurt and Fluconazole have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
Are Yogurt and Fluconazole used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Yogurt in each. That is a conversation for your prescriber, especially if Fluconazole is being adjusted to a target.
How was the Yogurt and Fluconazole combination checked?
Interactions in our licensed database are recorded against drug classes. Fluconazole is filed under 7 classifications, and Yogurt has documented interactions with 3 drug classes — 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 Yogurt interact with any other medications?
Yes. Yogurt has 22 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 — Yogurt is not one of them. The Fluconazole interaction page linked on this page lists every one, ranked by severity.
