No Known Interaction

The bottom line No known interaction

We found no known interaction between Rice Bran and Ibuprofen 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.

Rice Bran and Ibuprofen

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 Ibuprofen and Rice Bran 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Rice Bran at all — not against Ibuprofen, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

No Interaction Found — But Data Suggests Rice Bran and Ibuprofen 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.

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

Reported for Rice Bran but not commonly for Ibuprofen: stomach upset, an allergic reaction, a severe allergic reaction and hives.

Effects for Ibuprofen come from the ADVERSE REACTIONS section of its FDA label; effects for Rice Bran come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 283,500 voluntary FDA FAERS reports for Ibuprofen 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.

From our pharmacist’s overview on the Ibuprofen page

“Most people treat ibuprofen (Advil, Motrin) as an everyday pain reliever, which is exactly why this list of 286 interacting supplements deserves real attention rather than a shrug. The dominant pattern by far is bleeding: 202 of these ingredients can add to the bleeding and stomach irritation ibuprofen already causes, and the seven maj…”

About Rice Bran

What is Rice Bran?

  • High cholesterol
  • Digestive health and fiber
  • Heart health support
  • Blood sugar support
  • Skin care (topical oil)

Rice bran is the nutrient-rich outer layer of the rice grain and is a good source of fiber, healthy fats, and plant compounds. It is most studied for helping lower cholesterol, but for most other uses the evidence is limited. It is generally considered safe as a food, but talk with your pharmacist or doctor before using concentrated supplements.

Oryza sativa · Poaceae · Bran (the outer layer of the rice grain) and rice bran oil · Powder, capsules, tablets, rice bran oil, and as a fiber food additive

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

Rice Bran: dosing

There is no single official or standardized dose for rice bran supplements. The right amount depends on the product, the form (powder, capsule, or oil), and your reason for using it.The best approach is to follow the directions on the product label and not exceed the recommended amount. If you are adding rice bran for fiber, start with a small amount and increase slowly while drinking plenty of water.

About Ibuprofen

What Is Ibuprofen Used For?

Brand names: Motrin, Children's Motrin, Advil, Children's Advil, Fenbid Forte Gel, Ibugel Forte, Arthrofen, Ebufac, Rimafen, Calprofen, Fenpaed, Galprofen, Nurofen for Children, Orbifen for Children, Brufen, Brufen Retard, Fenbid, Tab-Profen, Ibuprofen, Calodor

Oral ibuprofen products (tablets, coated tablets, and liquid-filled capsules) are used to temporarily relieve minor aches and pains from headache, backache, toothache, muscular aches, menstrual cramps, minor arthritis pain, and the common cold, and to temporarily reduce fever. The oral prescription tablet (Ibu) is also indicated for the signs and symptoms of rheumatoid arthritis and osteoarthritis, mild to moderate pain, and primary dysmenorrhea (painful periods).

Caldolor, an intravenous (IV) form, is approved for adults and children 3 months and older to manage mild to moderate pain, to manage moderate to severe pain alongside opioid pain medicines, and to reduce fever. A separate intravenous solution, Ibuprofen Lysine, is used specifically in premature infants to close a patent ductus arteriosus (PDA) — an abnormal blood vessel connection near the heart — when standard medical management has not worked.

Most-Reported Side Effects for Ibuprofen

Taking Rice Bran and Ibuprofen Together: Common Questions

Is it safe to take Rice Bran with Ibuprofen?
We do not list a known interaction between Rice Bran and Ibuprofen. 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 Bran and Ibuprofen 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.
Does Ibuprofen interact with any supplements?
Yes. Ibuprofen has documented interactions with 286 supplements in our database — Rice Bran is not one of them. The Ibuprofen interaction page linked on this page lists every one, ranked by severity.
