Drug & supplement interaction

Ligilactobacillus Salivarius + Sarilumab

Sarilumab brand name: Kevzara.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Ligilactobacillus Salivarius and Sarilumab 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

Ligilactobacillus Salivarius and Sarilumab

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 Sarilumab and Ligilactobacillus Salivarius 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 Sarilumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sarilumab is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inducers, immunosuppressants. Ligilactobacillus Salivarius has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Sarilumab’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 Ligilactobacillus Salivarius and Sarilumab 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. One of them is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on Additional detail

    Ligilactobacillus Salivarius

    “Since Ligilactobacillus salivarius 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.”

See Every Supplement That Interacts With Sarilumab

This page covers Ligilactobacillus Salivarius only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sarilumab page lists 72 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Active Hexose Correlated Compound (ahcc) (moderate), Alfalfa (moderate), Alkanna (moderate), Alpine Ragwort (moderate) and American Ginseng (moderate).

By severity: 71 moderate · 1 minor.

From our pharmacist’s overview on the Sarilumab page

“Sarilumab (Kevzara) works by quieting an overactive immune system in rheumatoid arthritis, and most of the supplements on this page push the other way. Immune stimulants such as ashwagandha, astragalus, and American ginseng could in theory blunt the drug's benefit and let joint symptoms creep back.”

About Ligilactobacillus Salivarius

What is Ligilactobacillus Salivarius?

  • Digestive and gut health
  • Oral and dental health
  • Immune support
  • Vaginal and urinary health
  • General probiotic supplementation

Ligilactobacillus salivarius (formerly called Lactobacillus salivarius) is a probiotic bacterium found naturally in the mouth and gut of humans and animals. People take it to support digestion, oral health, and immunity, but solid human evidence is still limited for most uses. It is generally well tolerated in healthy people, but those with weakened immune systems should check with a doctor first.

Ligilactobacillus salivarius · Lactobacillaceae · Live bacterial cells (probiotic strain) · Capsules, tablets, chewable tablets, powders, and some fortified foods or oral lozenges

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

Ligilactobacillus Salivarius: dosing

There is no official standardized dose for Ligilactobacillus salivarius. Probiotic doses are usually measured in colony-forming units (CFUs), and the amount varies widely between products.The best approach is to follow the directions on the product label, since doses are tied to the specific strain and formulation.

About Sarilumab Injection

What Is Sarilumab Injection Used For?

Brand name: Kevzara

Kevzara (sarilumab) injection is approved for three conditions. In adults, it treats moderately to severely active rheumatoid arthritis (RA) when at least one other disease-modifying drug hasn't worked well enough or caused intolerance. It also treats polymyalgia rheumatica (PMR) in adults who haven't responded adequately to corticosteroids or who can't tolerate tapering them.

Kevzara is also approved for polyarticular juvenile idiopathic arthritis (pJIA) — a form of childhood arthritis — but only in patients who weigh 63 kg (about 139 lbs) or more. It is not approved for pediatric patients below that weight due to the lack of an appropriate dosage form.

Most-Reported Side Effects for Sarilumab

From FAERS, the FDA’s public side-effect reporting system (26,260 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Arthralgia 5,168 reports
Rheumatoid arthritis 4,646 reports
Joint swelling 4,578 reports
Fatigue 3,555 reports
Rash 3,349 reports

Taking Ligilactobacillus Salivarius and Sarilumab Together: Common Questions

Is it safe to take Ligilactobacillus Salivarius with Sarilumab?
We do not list a known interaction between Ligilactobacillus Salivarius and Sarilumab. 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 Ligilactobacillus Salivarius and Sarilumab 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.
How was the Ligilactobacillus Salivarius and Sarilumab combination checked?
Interactions in our licensed database are recorded against drug classes. Sarilumab is filed under 2 classifications, and Ligilactobacillus Salivarius has documented interactions with 1 drug class — none of Sarilumab'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 Ligilactobacillus Salivarius interact with any other medications?
Yes. Ligilactobacillus Salivarius has 182 documented drug interactions in our database — Sarilumab 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 Sarilumab interact with any supplements?
Yes. Sarilumab has documented interactions with 72 supplements in our database — Ligilactobacillus Salivarius is not one of them. The Sarilumab interaction page linked on this page lists every one, ranked by severity.
