Drug & supplement interaction

Kombucha + Omalizumab

Omalizumab brand name: Xolair.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Kombucha 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. 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

Kombucha 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 Kombucha 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 Omalizumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Omalizumab is filed under a single classification — immunosuppressants. Kombucha has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and disulfiram (antabuse) (minor) — 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.

Keep it in perspective

Kombucha Does Interact With Other Medications

Kombucha has 86 moderate, 1 minor known drug interactions in our database — Omalizumab isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

No Interaction Found — But Data Suggests Kombucha and Omalizumab 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.

See Every Supplement That Interacts With Omalizumab

This page covers Kombucha 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 Kombucha

What is Kombucha?

General wellness and gut health
Digestion
Immune support
Energy and detox claims
Source of probiotics

Kombucha is a fermented tea that many people enjoy as a probiotic-rich beverage, but solid human research proving specific health benefits is lacking. It is generally fine in moderate amounts for healthy adults, though homemade or unpasteurized versions can carry contamination risks. Pregnant people, those who are breastfeeding, and people with weakened immune systems should be cautious or avoid it.

Fermented sweetened tea (made with Camellia sinensis tea and a SCOBY culture) · Bottled drink, homemade fermented tea, occasionally powders or supplements

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

Kombucha: dosing

There is no established standard dose for kombucha. Many people drink a small glass (a few ounces) once a day or less, and start with a small amount to see how their body reacts.Follow the serving size on the product label, and choose reputable, commercially made brands rather than untested homemade versions.

About Omalizumab Injection

What Is Omalizumab Injection Used For?

Brand name: Xolair

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. 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.

Taking Kombucha and Omalizumab Together: Common Questions

Is it safe to take Kombucha with Omalizumab?

We do not list a known interaction between Kombucha and Omalizumab. 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 Kombucha and Omalizumab 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 Kombucha and Omalizumab combination checked?

Interactions in our licensed database are recorded against drug classes. Omalizumab is filed under 1 classification, and Kombucha has documented interactions with 2 drug classes — none of Omalizumab'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 Kombucha interact with any other medications?

Yes. Kombucha has 87 documented drug interactions in our database — Omalizumab 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 Omalizumab interact with any supplements?

Yes. Omalizumab has documented interactions with 53 supplements in our database — Kombucha is not one of them. The Omalizumab interaction page linked on this page lists every one, ranked by severity.
