Drug & supplement interaction

Broccoli + Dantrolene Sodium

Dantrolene Sodium brand name: Ryanodex.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Broccoli and Dantrolene Sodium 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.

Interaction report

Broccoli and Dantrolene Sodium

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 Dantrolene Sodium and Broccoli 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 Dantrolene Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dantrolene Sodium is filed under 2 classifications — skeletal muscle relaxants, hepatotoxic drugs. Broccoli has documented interactions with 2 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2a6 (cyp2a6) substrates (moderate) — and none of Dantrolene Sodium’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

No Interaction Found — But Data Suggests Broccoli and Dantrolene Sodium 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.

  • An allergic reaction Worth acting on Additional detail

    Listed in the ADVERSE REACTIONS section of the FDA label for Dantrolene Sodium. Read the label on DailyMed ›

Reported for Broccoli but not commonly for Dantrolene Sodium: stomach pain, diarrhea and a skin rash.

Effects for Dantrolene Sodium come from the ADVERSE REACTIONS section of its FDA label; effects for Broccoli come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,144 voluntary FDA FAERS reports for Dantrolene Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Broccoli

What is Broccoli?

  • General nutrition and antioxidant support
  • Heart and digestive health
  • Detoxification support
  • Cancer risk reduction (popular interest)
  • Blood sugar support

Broccoli is a nutritious cruciferous vegetable rich in fiber, vitamins, and plant compounds like sulforaphane that have drawn scientific interest for health benefits. Eating broccoli as food is safe and healthy for most people, but concentrated supplements and extracts are less studied and benefits are not firmly proven. Talk to your pharmacist or doctor before using broccoli supplements, especially in high doses.

Brassica oleracea var. italica · Brassicaceae · Florets, sprouts, seeds, and stalks · Whole vegetable (fresh, frozen, cooked), broccoli sprouts, powders, capsules, and sulforaphane or glucoraphanin extracts

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

Broccoli: dosing

There is no official or standardized supplement dose for broccoli. As a food, broccoli can simply be enjoyed as part of a balanced diet.For broccoli sprout and sulforaphane products, the amount of active compound varies a lot between brands, and a proven effective dose has not been established.

Taking Broccoli and Dantrolene Sodium Together: Common Questions

Is it safe to take Broccoli with Dantrolene Sodium?

Do Broccoli and Dantrolene Sodium 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 Broccoli and Dantrolene Sodium combination checked?
Interactions in our licensed database are recorded against drug classes. Dantrolene Sodium is filed under 2 classifications, and Broccoli has documented interactions with 2 drug classes — none of Dantrolene Sodium'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 Broccoli interact with any other medications?
Yes. Broccoli has 187 documented drug interactions in our database — Dantrolene Sodium 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 Dantrolene Sodium interact with any supplements?
Yes. Dantrolene Sodium has documented interactions with 41 supplements in our database — Broccoli is not one of them. The Dantrolene Sodium interaction page linked on this page lists every one, ranked by severity.
