Drug & supplement interaction

Rice Protein + Celecoxib

Celecoxib brand names: Celebrex, Elyxyb.

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 Celecoxib 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 Celecoxib

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 Celecoxib 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 Celecoxib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Celecoxib is filed under 9 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, cytochrome p450 2d6 (cyp2d6) inhibitors. Rice Protein has documented interactions with 1 drug class — the most serious being ace inhibitors (aceis) (moderate) — and none of Celecoxib’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 Rice Protein and Celecoxib 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 / Diarrhea / Vomiting reported in 7.7% of FDA reports for Celecoxib 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.”

    Celecoxib

    Listed in the ADVERSE REACTIONS section of the FDA label for Celecoxib, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Rice Protein but not commonly for Celecoxib: dehydration.

Effects for Celecoxib come from the ADVERSE REACTIONS section of its FDA label; effects for Rice Protein come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 130,888 voluntary FDA FAERS reports for Celecoxib 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.

See Every Supplement That Interacts With Celecoxib

This page covers Rice Protein only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Celecoxib page lists 117 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Siberian Cocklebur (major) and Wine (major).

By severity: 5 major · 84 moderate · 28 minor.

From our pharmacist’s overview on the Celecoxib page

“Alcohol tops my worry list here. Beer and wine both carry major ratings with celecoxib (Celebrex, Elyxyb) because mixing alcohol with an NSAID raises the odds of stomach and intestinal bleeding, the drug's best-known danger.”

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.

Taking Rice Protein and Celecoxib Together: Common Questions

Is it safe to take Rice Protein with Celecoxib?
We do not list a known interaction between Rice Protein and Celecoxib. 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 Celecoxib have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Celecoxib combination checked?
Interactions in our licensed database are recorded against drug classes. Celecoxib is filed under 9 classifications, and Rice Protein has documented interactions with 1 drug class — none of Celecoxib'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 — Celecoxib 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 Celecoxib interact with any supplements?
Yes. Celecoxib has documented interactions with 117 supplements in our database — Rice Protein is not one of them. The Celecoxib interaction page linked on this page lists every one, ranked by severity.
