Drug & supplement interaction

Bifidobacterium Breve + Liraglutide Recombinant

Liraglutide Recombinant brand name: Saxenda.

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 Bifidobacterium Breve and Liraglutide Recombinant 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

Bifidobacterium Breve and Liraglutide Recombinant

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 Liraglutide Recombinant and Bifidobacterium Breve 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.

Bifidobacterium Breve safety at a glance

Bifidobacterium Br... overall Use caution Generally well tolerated in healthy people, but caution is needed for those who are very ill or immunocompromised.
Pregnancy Use caution Probiotics are often considered low-risk, but evidence is limited, so use only with your doctor's guidance.

How we checked

Why No Interaction Is Listed for Liraglutide Recombinant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Liraglutide Recombinant is filed under a single classification — antidiabetes drugs. Bifidobacterium Breve has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Liraglutide Recombinant’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 Bifidobacterium Breve and Liraglutide Recombinant 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. One of them is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on Additional detail

Overlapping uses

What Liraglutide Recombinant Is Prescribed For, and What Bifidobacterium Breve Has Been Studied For

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

Liraglutide Recombinant is prescribed for: Saxenda is used alongside a reduced-calorie diet and increased physical activity for chronic weight management. It is approved for adults with a BMI of 30 or higher, or a BMI of 27 or higher if they also have at least one weight-related condition such as high blood pressure, type 2 diabetes, or dyslipidemia (abnormal cholesterol or fat levels). It is also approved for adolescents aged 12 and older who weigh more than 60 kg and meet certain BMI thresholds for obesity. Saxenda should not be used together with other liraglutide-containing products or any other GLP-1 receptor agonist.

Its safety and effectiveness in combination with other prescription or over-the-counter weight-loss products have not been established.

Bifidobacterium Breve has been studied for:

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

    Bifidobacterium Breve for obesity

    It is unclear if oral Bifidobacterium breve is beneficial for obesity.

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

    Bifidobacterium Breve for diabetes

    Oral Bifidobacterium breve has only been evaluated in combination with other ingredients for various forms of diabetes; its effect when used alone is unclear.

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 Liraglutide Recombinant on your own; if you are taking Bifidobacterium Breve for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Liraglutide Recombinant

This page covers Bifidobacterium Breve only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Liraglutide Recombinant page lists 239 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate), Agaricus Mushroom (moderate) and Agmatine (moderate).

By severity: 1 major · 208 moderate · 30 minor.

From our pharmacist’s overview on the Liraglutide Recombinant page

“If you take liraglutide (Saxenda), handle this page with real care, because all 239 ingredients on it act on the same thing the drug does, your blood sugar. The one major entry, Siberian cocklebur, has caused severe hypoglycemia, dangerously low blood sugar, in people and should never be combined with a glucose-lowering medicine.”

About Bifidobacterium Breve

What is Bifidobacterium Breve?

  • Digestive health and regularity
  • Infant colic and gut support
  • Diarrhea (including antibiotic-related)
  • Constipation
  • General immune and gut microbiome support

Bifidobacterium breve is a 'friendly' gut bacterium taken as a probiotic, most often to support digestion and balance the gut microbiome. Some studies suggest possible benefits for certain digestive and infant conditions, but evidence is still limited and varies by strain. It is generally well tolerated in healthy people, but anyone with a weak immune system or serious illness should check with a doctor or pharmacist first.

Bifidobacterium breve · Bifidobacteriaceae · Live bacterial cells (probiotic strain) · Capsules, powders, sachets, chewables, drops, and fortified foods or drinks

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

Bifidobacterium Breve: dosing

There is no single standard dose of Bifidobacterium breve. Probiotic amounts are usually measured in colony-forming units (CFU), and products vary widely in their strain and strength.The best approach is to follow the directions on the product label, since dosing was often based on the specific strain studied.

Taking Bifidobacterium Breve and Liraglutide Recombinant Together: Common Questions

Is it safe to take Bifidobacterium Breve with Liraglutide Recombinant?
We do not list a known interaction between Bifidobacterium Breve and Liraglutide Recombinant. 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 Bifidobacterium Breve and Liraglutide Recombinant 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.
Are Bifidobacterium Breve and Liraglutide Recombinant 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 Bifidobacterium Breve in each. That is a conversation for your prescriber, especially if Liraglutide Recombinant is being adjusted to a target.
How was the Bifidobacterium Breve and Liraglutide Recombinant combination checked?
Interactions in our licensed database are recorded against drug classes. Liraglutide Recombinant is filed under 1 classification, and Bifidobacterium Breve has documented interactions with 1 drug class — none of Liraglutide Recombinant'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 Bifidobacterium Breve interact with any other medications?
Yes. Bifidobacterium Breve has 182 documented drug interactions in our database — Liraglutide Recombinant 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 Liraglutide Recombinant interact with any supplements?
Yes. Liraglutide Recombinant has documented interactions with 239 supplements in our database — Bifidobacterium Breve is not one of them. The Liraglutide Recombinant interaction page linked on this page lists every one, ranked by severity.
