Ligilactobacillus Salivarius + Omalizumab
Omalizumab brand name: Xolair.
We found no known interaction between Ligilactobacillus Salivarius and Omalizumab 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.
Ligilactobacillus Salivarius and Omalizumab
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 Omalizumab 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.
Ligilactobacillus Salivarius safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Omalizumab
Interactions in our licensed database are recorded against drug classes, not just single drug names. Omalizumab is filed under a single classification — immunosuppressants. Ligilactobacillus Salivarius has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Omalizumab’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 Omalizumab Is Prescribed For, and What Ligilactobacillus Salivarius Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Omalizumab is a prescription medicine with approved uses on its FDA label. Ligilactobacillus Salivarius is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Omalizumab is prescribed for: Xolair is used for several allergy-driven conditions. It treats moderate to severe persistent asthma in adults and children 6 and older whose symptoms aren't controlled by inhaled steroids alone and who test positive for a year-round airborne allergen. It is also used as an add-on maintenance treatment for chronic rhinosinusitis with nasal polyps (ongoing sinus inflammation with polyp growths) in adults 18 and older who haven't responded well to nasal corticosteroids. Xolair is also approved to reduce allergic reactions — including anaphylaxis — from accidental food exposure in adults and children aged 1 and older with IgE-mediated food allergy.
Read the rest of what Omalizumab is prescribed for
It must be used alongside strict food avoidance, and it is not a substitute for emergency treatment like epinephrine. Finally, Xolair treats chronic spontaneous urticaria (persistent hives with no identified trigger) in adults and adolescents 12 and older who still have symptoms despite antihistamine treatment.
Ligilactobacillus Salivarius has been studied for:
-
Asthma studied, not established Ligilactobacillus Salivarius has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Ligilactobacillus Salivarius for asthma
Oral Ligilactobacillus salivarius has only been evaluated in combination with other ingredients; 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 Omalizumab on your own; if you are taking Ligilactobacillus Salivarius for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.
See Every Supplement That Interacts With Omalizumab
This page covers Ligilactobacillus Salivarius only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Omalizumab page lists 53 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), American Ginseng (moderate), Andrographis (moderate) and Ashwagandha (moderate).
By severity: 52 moderate · 1 minor.
From our pharmacist’s overview on the Omalizumab page
“None of the 53 supplements on file for omalizumab (Xolair) carries a major rating, so this is a list to read with steady attention rather than alarm. Xolair treats allergic asthma and chronic hives by calming part of the immune system, and every entry here pulls the other way: these are immune-stimulating products, echinacea and astrag…”

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.

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.
