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

Miracle Fruit and Ketoconazole

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 Ketoconazole and Miracle Fruit 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.

Miracle Fruit safety at a glance

Miracle Fruit overall Use caution Generally well tolerated as a food, but long-term and high-dose safety has not been well studied.
Pregnancy Use caution There is not enough reliable safety data, so it is best to avoid concentrated supplements and use caution.
Breastfeeding Use caution There is not enough reliable safety data, so caution is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Ketoconazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ketoconazole is filed under 8 classifications — including antifungals, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Miracle Fruit has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Ketoconazole’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.

What Ketoconazole’s Own FDA Label Lists

This is not an interaction — none of it involves Miracle Fruit. These are the most notable effects listed in the ADVERSE REACTIONS section of Ketoconazole’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. 7 of them are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • Increased appetite
  • Changes to your period
  • Breast tenderness

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

From our pharmacist’s overview on the Ketoconazole page

“Ketoconazole (Nizoral) is already hard on the liver, so treat its 182 interacting supplements with genuine care, starting with the six rated major. Most of the list runs through CYP3A4, the liver enzyme ketoconazole strongly blocks, so it can raise levels of over a hundred herbal ingredients, while grapefruit pushes ketoconazole itself…”

About Miracle Fruit

What is Miracle Fruit?

Miracle Fruit
  • Making sour foods taste sweet
  • Sugar substitute or sweetness enhancer
  • Reducing added sugar intake
  • Improving taste during chemotherapy
  • Novelty 'flavor tripping' experiences

Miracle fruit contains a protein called miraculin that temporarily makes sour and acidic foods taste sweet for up to about an hour. It is generally considered safe as a food when used occasionally, but high-quality research on any health benefits is limited. If you are pregnant, breastfeeding, or have a medical condition, check with your pharmacist or doctor first.

Synsepalum dulcificum · Sapotaceae · Fruit (berry) · Fresh berries, freeze-dried tablets, freeze-dried powder, frozen pulp

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

Miracle Fruit: dosing

There is no official or standardized medical dose for miracle fruit. Products are usually sold as a single fresh berry, a freeze-dried tablet, or a small amount of powder meant for one taste-changing session.The best approach is to follow the directions on the product label and not use more than recommended.

About Ketoconazole

What Is Ketoconazole Used For?

Brand name: Nizoral

Ketoconazole 2% shampoo and foam are used to treat tinea versicolor (also called pityriasis versicolor) — a fungal infection caused by Pityrosporum orbiculare (also known as Malassezia furfur), a yeast that naturally lives on the skin.

This infection creates light or dark patches, most often on the trunk, neck, arms, and upper thighs. Even after the fungus is cleared, those skin patches may take months to return to their normal color — that's normal, and depends on your skin type and sun exposure. Tinea versicolor can also come back, since the fungus lives on healthy skin even when there's no active infection.

Most-Reported Side Effects for Ketoconazole

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.

Pruritus 984 reports
Fatigue 975 reports
Nausea 873 reports
