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 Lacticaseibacillus Paracasei 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.

Lacticaseibacillus Paracasei 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 Lacticaseibacillus Paracasei 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 Ibuprofen

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ibuprofen is filed under 10 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, anticoagulant/antiplatelet drugs. Lacticaseibacillus Paracasei has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Ibuprofen’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 Lacticaseibacillus Paracasei and Ibuprofen 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.

    “Orally, taking Lacticaseibacillus paracasei alone or in combination with other probiotics may cause gastrointestinal side effects including dyspepsia, flatulence, nausea, and bloating; however, these events are uncommon.

    Ibuprofen

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

Reported for Lacticaseibacillus Paracasei but not commonly for Ibuprofen: a higher chance of infection, stomach upset, itching and a skin rash.

Effects for Ibuprofen come from the ADVERSE REACTIONS section of its FDA label; effects for Lacticaseibacillus Paracasei 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 Lacticaseibacillus Paracasei

What is Lacticaseibacillus Paracasei?

  • Digestive health and regularity
  • Immune support
  • Diarrhea (including antibiotic-associated)
  • Allergy and eczema symptoms
  • Gut microbiome balance

Lacticaseibacillus paracasei (formerly Lactobacillus paracasei) is a probiotic bacterium found in fermented foods and supplements that is widely used to support gut and immune health. Some strains have promising research for digestion, diarrhea, and allergies, but results vary by strain and many uses are not firmly proven. It is generally well tolerated in healthy people, but those who are seriously ill or immune-compromised should check with a doctor first.

Lacticaseibacillus paracasei · Lactobacillaceae · Live bacterial cells (probiotic strain) · Capsules, tablets, powders, sachets, fermented dairy products (yogurt, kefir), and functional foods

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

Lacticaseibacillus Paracasei: dosing

There is no single official or standardized dose of L. paracasei. Probiotic doses are usually measured in colony-forming units (CFU), and the right amount can depend on the strain and the intended use.Because formulations differ, the best approach is to follow the dose on the product label. Storing the product as directed (some need refrigeration) helps keep the bacteria alive and effective.

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.

Taking Lacticaseibacillus Paracasei and Ibuprofen Together: Common Questions

Is it safe to take Lacticaseibacillus Paracasei with Ibuprofen?
We do not list a known interaction between Lacticaseibacillus Paracasei 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 Lacticaseibacillus Paracasei and Ibuprofen 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 Lacticaseibacillus Paracasei and Ibuprofen combination checked?
Interactions in our licensed database are recorded against drug classes. Ibuprofen is filed under 10 classifications, and Lacticaseibacillus Paracasei has documented interactions with 1 drug class — none of Ibuprofen'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 Lacticaseibacillus Paracasei interact with any other medications?
Yes. Lacticaseibacillus Paracasei has 182 documented drug interactions in our database — Ibuprofen 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 Ibuprofen interact with any supplements?
Yes. Ibuprofen has documented interactions with 286 supplements in our database — Lacticaseibacillus Paracasei is not one of them. The Ibuprofen interaction page linked on this page lists every one, ranked by severity.
