Drug & supplement interaction

Rice Protein + Dantrolene

Dantrolene brand names: Dantrium, Dantrium Intravenous.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Rice Protein and Dantrolene 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

Rice Protein and Dantrolene

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 and Rice Protein 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.

Rice Protein safety at a glance

Rice Protein overall Generally safe Rice protein is generally considered safe for most healthy adults when used as a food.
Pregnancy Use caution Whole food rice is fine, but concentrated supplements are not well studied in pregnancy, so check with your provider first.
Breastfeeding Use caution Likely fine as a food, but concentrated protein supplements are not well studied while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Dantrolene

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dantrolene is filed under 4 classifications — including skeletal muscle relaxants, photosensitizing drugs, hepatotoxic drugs. Rice Protein has documented interactions with 1 drug class — the most serious being ace inhibitors (aceis) (moderate) — and none of Dantrolene’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 Rice Protein and Dantrolene 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.

  • Tiredness / Vomiting Additional detail

    Rice Protein

    “Orally, rice protein has been rarely reported to cause enterocolitis symptoms of vomiting, diarrhea, and dehydration, possibly leading to acidosis and lethargy, in infants and young children. Rarely, enterocolitis symptoms are associated with an allergy to rice protein.”

From our pharmacist’s overview on the Dantrolene page

“People take dantrolene (Dantrium) for muscle spasticity from multiple sclerosis or spinal cord injury, and the drug already carries a boxed warning for liver injury. That is why its supplement interactions deserve genuine respect.”

About Rice Protein

What is Rice Protein?

  • Building and maintaining muscle
  • Post-workout recovery
  • Plant-based protein source
  • Meal replacement and shakes
  • Weight management support

Rice protein is a plant-based protein powder made from rice that offers an easy way to add protein to your diet, especially if you avoid dairy or animal products. It is generally considered safe and well tolerated, though on its own it is lower in the amino acid lysine and is often blended with pea protein for a more complete amino acid profile. Talk to your pharmacist or doctor before using it if you have kidney problems or other health conditions.

Oryza sativa · Poaceae · Seed (grain/endosperm and bran) · Powder, protein shakes, capsules, blended plant-protein products

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

Rice Protein: dosing

There is no official standardized dose for rice protein. Serving sizes are usually based on how much protein you want to add to your diet, commonly around 20 to 30 grams of protein per scoop, but this varies by product.Always follow the directions on the product label and consider your total daily protein needs from all foods.

About Dantrolene

What Is Dantrolene Used For?

Brand names: Dantrium, Dantrium Intravenous

Dantrolene sodium capsules (Dantrium, Dantrolene Sodium) are used by mouth to control spasticity — painful or disabling muscle stiffness and spasms — caused by upper motor neuron disorders such as spinal cord injury, stroke, cerebral palsy, or multiple sclerosis. They are not used for muscle spasm from arthritis or other rheumatic conditions. Oral capsules are also used before and after surgery to prevent or reduce the risk of malignant hyperthermia in patients known to be susceptible.

For an active malignant hyperthermia crisis — a sudden, dangerous overheating of the muscles triggered by certain anesthetics — the intravenous (IV) forms are given in the hospital. Dantrium Intravenous, Revonto, Ryanodex, and Dantrolene injection are all indicated to treat a malignant hyperthermia crisis and may also be given before surgery to help prevent one in high-risk patients.

Taking Rice Protein and Dantrolene Together: Common Questions

Is it safe to take Rice Protein with Dantrolene?
We do not list a known interaction between Rice Protein and Dantrolene. 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 Rice Protein and Dantrolene have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Rice Protein and Dantrolene combination checked?
Interactions in our licensed database are recorded against drug classes. Dantrolene is filed under 4 classifications, and Rice Protein has documented interactions with 1 drug class — none of Dantrolene'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 Rice Protein interact with any other medications?
Yes. Rice Protein has 23 documented drug interactions in our database — Dantrolene 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 interact with any supplements?
Yes. Dantrolene has documented interactions with 77 supplements in our database — Rice Protein is not one of them. The Dantrolene interaction page linked on this page lists every one, ranked by severity.
