No Known Interaction
The bottom line No known interaction

We found no known interaction between Radish and Vismodegib 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.

Radish and Vismodegib

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 Vismodegib and Radish 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.

Radish safety at a glance

Radish overall Generally safe Radish is widely eaten as food and is generally safe in normal dietary amounts.
Pregnancy Use caution Normal food amounts are likely fine, but concentrated supplements and unwashed raw sprouts should be avoided.
Breastfeeding Use caution Food amounts are likely fine, but safety of concentrated radish supplements is not well studied.

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

How we checked

Why No Interaction Is Listed for Vismodegib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Vismodegib is filed under 4 classifications — including cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors, p-glycoprotein substrates. Radish has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Vismodegib’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 to actually watch for

What Radish Itself Has Been Linked To

This is not an interaction — nothing below involves Vismodegib. It is the side-effect record for Radish on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Radish, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Hives Worth acting on Additional detail

    “A case of allergy to oral intake of radish has been reported. Symptoms included throat tightness and generalized urticaria.”

  • Stomach upset Additional detail

    “Large amounts of radish may cause irritation of the gastrointestinal mucus membrane (18). Mild indigestion has also been associated with use of a specific product containing radish, camu camu, acerola, honey, and tapioca in clinical research. However, it is unclear if this adverse event is due to radish, other ingredients in the product, or the combination.”

Everything above comes from the Natural Medicines adverse-effect record for Radish — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Vismodegib’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Vismodegib column appears here.

Everything else you take

See Every Supplement That Interacts With Vismodegib

This page covers Radish only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Vismodegib page lists 57 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), St. John's Wort (major), Bitter Melon (moderate), Black Pepper (moderate) and Bulbine Natalensis (moderate).

By severity: 2 major · 38 moderate · 17 minor.

From our pharmacist’s overview on the Vismodegib page

“St. John's wort can quietly undercut vismodegib (Erivedge), the pill for advanced basal cell carcinoma, by speeding up the gut pump that clears the drug from the body, and a cancer treatment that silently loses potency is the worst kind of interaction.”

About Radish

What is Radish?

  • Digestive support
  • Liver and gallbladder health
  • Antioxidant support
  • Respiratory and cough relief
  • General nutrition

Radish is a common edible root vegetable that is nutritious and generally safe to eat as food. Some people use radish (especially black radish) and its extracts for digestion and liver support, but high-quality human evidence for supplement-level health benefits is limited. Eating radish as part of a normal diet is fine for most people; talk to your pharmacist or doctor before using concentrated supplements.

Raphanus sativus · Brassicaceae · Root, leaves, seeds, and sprouts · Fresh vegetable, juice, sprouts, powders, and capsules or extracts

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

Radish: dosing

There is no standardized medicinal dose for radish. As a food, you can simply eat it as part of a normal diet.For radish juice, powders, or capsules, a proven supplement dose has not been established by research.
