Glyconutrients and Omalizumab

Here is the interaction we found between these two, with the evidence behind it.

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Omalizumab

Omalizumab falls under IMMUNOSUPPRESSANTS — the group Glyconutrients interacts with.

Evidence from in vitro research suggests that glyconutrients stimulate certain immune responses. Theoretically, glyconutrients might interfere with immunosuppressive therapy. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), corticosteroids (glucocorticoids), and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thinking behind this one. Xolair (omalizumab) is an antibody that calms down part of your immune system to control allergic asthma, nasal polyps, or stubborn hives. Glyconutrients, on the other hand, are marketed as boosting immune activity. So the theoretical worry is that they could nudge your immune system in the opposite direction and make Xolair work a little less well, meaning more wheezing, breathing trouble, or breakout hives sneaking back in.

I want to be honest with you though: this concern comes only from lab dish studies, not from real patients, so the evidence is weak. I wouldn't lose sleep over it, but since Xolair is treating a real condition, it's worth a quick chat with your pharmacist or doctor before adding these supplements.

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 Glyconutrients

What is Glyconutrients?

  • General immune support
  • Overall wellness and energy
  • Cognitive or memory support
  • Inflammation
  • Digestive health

Glyconutrients are supplements containing certain sugar molecules (monosaccharides) that marketers claim are essential for cell communication and health. The science behind most health claims is weak and largely promotional, and your body already makes these sugars from a normal diet. They are generally low-risk, but talk to your pharmacist or doctor before using them, and don't rely on them to treat any disease.

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.
