The bottom line No known interaction

We found no known interaction between Lacticaseibacillus Casei and Fenofibrate 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 Casei and Fenofibrate

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 Fenofibrate and Lacticaseibacillus Casei 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 Fenofibrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fenofibrate is filed under 3 classifications — cytochrome p450 2c9 (cyp2c9) inhibitors, hepatotoxic drugs, oral drugs. Lacticaseibacillus Casei has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Fenofibrate’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 Lacticaseibacillus Casei and Fenofibrate 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.

Overlapping uses

What Fenofibrate Is Prescribed For, and What Lacticaseibacillus Casei Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Fenofibrate is a prescription medicine with approved uses on its FDA label. Lacticaseibacillus Casei is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Fenofibrate is prescribed for: Fenofibrate is used alongside a cholesterol-lowering diet in adults to improve abnormal lipid levels. Tricor (tablet) and fenofibrate tablets are indicated to lower LDL cholesterol (bad cholesterol), total cholesterol, triglycerides, and apolipoprotein B, and to raise HDL cholesterol (good cholesterol) in adults with primary hypercholesterolemia (high cholesterol) or mixed dyslipidemia (mixed abnormal lipid levels). They are also used to treat severe hypertriglyceridemia (very high triglycerides). Antara and Lipofen (capsules) are indicated to reduce triglyceride levels in adults with severe hypertriglyceridemia, and to lower LDL cholesterol in adults with primary hyperlipidemia when other recommended LDL-lowering therapies cannot be used.

Fenofibrate has not been shown to reduce heart attacks or cardiovascular deaths in patients with type 2 diabetes.

Lacticaseibacillus Casei has been studied for:

  • Hyperlipidemia studied, not established Lacticaseibacillus Casei has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Lacticaseibacillus Casei for hyperlipidemia

    It is unclear if oral Lacticaseibacillus casei is beneficial for hyperlipidemia.

  • Diabetes studied, not established Lacticaseibacillus Casei has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Lacticaseibacillus Casei for diabetes

    It is unclear if oral Lacticaseibacillus casei is beneficial for treatment of type 2 or gestational diabetes.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Fenofibrate on your own; if you are taking Lacticaseibacillus Casei for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Fenofibrate

This page covers Lacticaseibacillus Casei only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Fenofibrate page lists 59 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 4 major · 46 moderate · 9 minor.

From our pharmacist’s overview on the Fenofibrate page

“Fenofibrate (Tricor, Antara) is a cholesterol and triglyceride medicine that can strain the liver on its own, so this list of 59 supplements deserves genuine care rather than a shrug. Most of it, 38 ingredients, involves herbs that also stress the liver, ashwagandha among them, and stacking those effects is the risk that matters most h…”

About Lacticaseibacillus Casei

What is Lacticaseibacillus Casei?

  • Digestive health
  • Diarrhea (including antibiotic-related)
  • Immune support
  • Constipation
  • Gut microbiome balance

Lacticaseibacillus casei (formerly Lactobacillus casei) is a 'friendly' probiotic bacterium found in fermented foods and many supplements. It is most studied for digestive issues like diarrhea, where some evidence is encouraging, but results vary by strain and condition. It is generally well tolerated in healthy people, but those with weakened immune systems should check with a doctor first.

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

Lacticaseibacillus Casei: dosing

There is no single official standardized dose for L. casei. Probiotic amounts are usually measured in colony-forming units (CFUs), and products vary widely.The best approach is to follow the directions on the product label.

Taking Lacticaseibacillus Casei and Fenofibrate Together: Common Questions

Is it safe to take Lacticaseibacillus Casei with Fenofibrate?
We do not list a known interaction between Lacticaseibacillus Casei and Fenofibrate. 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 Casei and Fenofibrate 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.
Are Lacticaseibacillus Casei and Fenofibrate used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Lacticaseibacillus Casei in each. That is a conversation for your prescriber, especially if Fenofibrate is being adjusted to a target.
How was the Lacticaseibacillus Casei and Fenofibrate combination checked?
Interactions in our licensed database are recorded against drug classes. Fenofibrate is filed under 3 classifications, and Lacticaseibacillus Casei has documented interactions with 1 drug class — none of Fenofibrate'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 Casei interact with any other medications?
Yes. Lacticaseibacillus Casei has 182 documented drug interactions in our database — Fenofibrate 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 Fenofibrate interact with any supplements?
Yes. Fenofibrate has documented interactions with 59 supplements in our database — Lacticaseibacillus Casei is not one of them. The Fenofibrate interaction page linked on this page lists every one, ranked by severity.
