Drug & supplement interaction

Levilactobacillus Brevis + Etanercept-SZZS

Etanercept-SZZS brand name: Erelzi.

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 Levilactobacillus Brevis and Etanercept-SZZS 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 label for Etanercept-SZZS states a food rule worth keeping to, and 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

Levilactobacillus Brevis and Etanercept-SZZS

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 Etanercept-SZZS and Levilactobacillus Brevis 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 Etanercept-SZZS

Interactions in our licensed database are recorded against drug classes, not just single drug names. Etanercept-SZZS is filed under a single classification — immunosuppressants. Levilactobacillus Brevis has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Etanercept-SZZS’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 Levilactobacillus Brevis and Etanercept-SZZS 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

    Levilactobacillus Brevis

    “Since Levilactobacillus brevis preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Some lactobacilli species have been isolated in cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis.”

How to take them

Some Etanercept-SZZS Products Have a Food Rule — Levilactobacillus Brevis Should Not Break It

At least one FDA label for a product containing Etanercept-SZZS says to take it on an empty stomach. Most supplements — Levilactobacillus Brevis included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Etanercept-SZZS on its own and move Levilactobacillus Brevis to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Etanercept-SZZS products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Preparation of Enbrel Single-dose Prefilled SureClick Autoinjector Leave the autoinjector at room temperature for at least 30 minutes before injecting.

From the Dosage and Administration section of the FDA label we read for Etanercept-SZZS — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Levilactobacillus Brevis

What is Levilactobacillus Brevis?

  • Digestive health
  • Gut microbiome support
  • Immune support
  • Oral and dental health
  • Vaginal health

Levilactobacillus brevis (formerly Lactobacillus brevis) is a lactic acid bacterium found in fermented foods like sauerkraut, pickles, and kimchi, and is used as a probiotic. Early research suggests possible benefits for gut and immune health, but strong human evidence is still limited. It is generally well tolerated in healthy people, but anyone with a weakened immune system or serious illness should talk to a doctor first.

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

Levilactobacillus Brevis: dosing

There is no official standardized dose for Levilactobacillus brevis. Probiotic amounts are usually measured in colony-forming units (CFU), and products vary widely in strength and strain.The best approach is to follow the directions on the product label. Doses are often taken once or twice daily, sometimes with food.

Taking Levilactobacillus Brevis and Etanercept-SZZS Together: Common Questions

Is it safe to take Levilactobacillus Brevis with Etanercept-SZZS?
We do not list a known interaction between Levilactobacillus Brevis and Etanercept-SZZS. 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 Levilactobacillus Brevis and Etanercept-SZZS 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.
Should I take Levilactobacillus Brevis and Etanercept-SZZS at the same time of day?
At least one FDA label for a product containing Etanercept-SZZS says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Etanercept-SZZS on its own and move Levilactobacillus Brevis to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Levilactobacillus Brevis and Etanercept-SZZS combination checked?
Interactions in our licensed database are recorded against drug classes. Etanercept-SZZS is filed under 1 classification, and Levilactobacillus Brevis has documented interactions with 1 drug class — none of Etanercept-SZZS'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 Levilactobacillus Brevis interact with any other medications?
Yes. Levilactobacillus Brevis has 182 documented drug interactions in our database — Etanercept-SZZS 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 Etanercept-SZZS interact with any supplements?
