Drug & supplement interaction

Higenamine + Omalizumab

Omalizumab brand name: Xolair.

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 Higenamine 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

Higenamine 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 Higenamine 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.

Higenamine safety at a glance

Higenamine overall Use caution It acts as a stimulant on the heart and is banned in competitive sports, so it should be used with caution if at all.
Pregnancy Avoid There is no safety data in pregnancy, so it should be avoided.
Breastfeeding Avoid There is no safety data during breastfeeding, so it should be avoided.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Higenamine has documented interactions with 5 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 2d6 (cyp2d6) substrates (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (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.

No Interaction Found — But Data Suggests Higenamine 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.

    Listed in the ADVERSE REACTIONS section of the FDA label for Omalizumab. Read the label on DailyMed ›

Reported for Higenamine but not commonly for Omalizumab: an irregular heartbeat, chest pain, severe muscle breakdown and a fast or pounding heartbeat.

Effects for Omalizumab come from the ADVERSE REACTIONS section of its FDA label; effects for Higenamine come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Omalizumab Is Prescribed For, and What Higenamine 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. Higenamine 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.

Higenamine has been studied for:

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

    Higenamine for asthma

    Although there has been interest in using oral higenamine for asthma, there is insufficient reliable information about the clinical effects of higenamine for this purpose.

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 Higenamine 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 Omalizumab

This page covers Higenamine 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 Higenamine

What is Higenamine?

  • Weight loss and fat burning
  • Pre-workout energy and performance
  • Appetite suppression
  • Athletic stimulant
  • Traditional medicine remedies

Higenamine is a plant-based stimulant compound added to many weight-loss and pre-workout supplements, but there is very little human evidence that it works and real concerns about heart and blood pressure effects. It is banned in sports by the World Anti-Doping Agency (WADA), and product labels often list inaccurate amounts, so most people should approach it with caution and talk to a pharmacist or doctor first.

Plant-derived alkaloid (found in plants such as Aconitum, Nelumbo/lotus, and Annona species) · Capsules, tablets, powders, pre-workout and fat-burner blends

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

Higenamine: dosing

There is no established or proven safe dose of higenamine. Supplement products vary widely, and testing has shown that the labeled amount is often unreliable, so it is hard to know how much you are actually taking.Because of this uncertainty and the potential heart effects, we do not recommend a specific dose.

Taking Higenamine and Omalizumab Together: Common Questions

Is it safe to take Higenamine with Omalizumab?
We do not list a known interaction between Higenamine 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 Higenamine 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.
Are Higenamine and Omalizumab 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 Higenamine in each. That is a conversation for your prescriber, especially if Omalizumab is being adjusted to a target.
How was the Higenamine and Omalizumab combination checked?
Interactions in our licensed database are recorded against drug classes. Omalizumab is filed under 1 classification, and Higenamine has documented interactions with 5 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 Higenamine interact with any other medications?
Yes. Higenamine has 891 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 — Higenamine is not one of them. The Omalizumab interaction page linked on this page lists every one, ranked by severity.
