While most people savor meals without hesitation, for roughly 33 million Americans with food allergies, each bite carries the weight of potential danger. From meticulously reading ingredient labels to staying alert for hidden allergens, mealtimes can feel like a high-stakes gamble.

But what if you could enjoy your meals freely without fearing anaphylaxis?

We at Premier Allergy of Texas are excited to share some promising news: Xolair injection for allergies like chronic hives is now an FDA-approved food allergy treatment. This is a significant leap forward in allergy care, offering families renewed peace of mind around mealtimes.

Let’s take a closer look at how Xolair works and whether it’s the right food allergy treatment option for you or your loved ones.

Considering Xolair for Food Allergies?

What Is Xolair?

Xolair (omalizumab) is a monoclonal antibody medication traditionally used to manage asthma and chronic hives. It works by blocking a critical component of the immune system responsible for triggering allergic reactions. Now, Xolair is gaining attention as a new treatment option for food allergies.

In early 2024, the FDA approved Xolair for people with Immunoglobulin E (IgE)-mediated food allergies like peanuts, eggs, and more. This approval came after strong clinical studies showed that Xolair can help people better tolerate accidental exposure to these allergens, reducing the risk of serious allergic reactions.

How Xolair Works in the Body

Food allergies happen when your immune system mistakes harmless food proteins for threats. This reaction is driven by IgE antibodies, which attach themselves to immune cells like mast cells. When you eat food you’re allergic to, these cells release chemicals like histamine that cause symptoms such as itching, swelling, trouble breathing, or even more serious reactions.

Xolair for food allergies works by binding to those IgE antibodies circulating in your blood, preventing them from triggering this allergic response. Think of it like cutting the fuse before the fireworks start. By calming your body’s reaction to allergens over time, Xolair can make accidental exposures cause milder reactions or prevent them altogether.

Recent studies show that Xolair reduces allergic reactions and has fewer side effects than oral immunotherapy (OIT), which involves gradually exposing patients to allergens. This makes Xolair safer and more effective for many people with multiple food allergies.

What Food Allergies Can Xolair Treat?

Now that we’ve covered how Xolair works, let’s look at the kinds of food allergies it’s approved to treat.

Xolair is designed for people with IgE-mediated food allergies—the kind that can trigger rapid, potentially life-threatening reactions like anaphylaxis. It is especially helpful because you can use Xolair for multiple food allergies.

Common food allergies Xolair is approved for include:

• Peanuts
• Tree nuts (e.g., cashews, walnuts, hazelnuts)
• Milk
• Eggs
• Wheat

What to Expect With Xolair Treatment

If you’re considering Xolair or omalizumab for food allergies, here’s what you need to know:

Administration

Xolair is an injection given just under the skin, usually every 2 to 4 weeks. Depending on your age, weight, and IgE levels, you may need one or two injections at a time.

Effectiveness Timeline

If you’re wondering how long Xolair takes to work, it typically requires a few months to reach its full effect. Many patients start seeing results within 4–6 months, with improved tolerance to small amounts of allergens.

Continued Precautions

Xolair injection for allergies helps reduce reactions from accidental exposure, but you’ll still need to avoid known allergens and carry emergency epinephrine just in case.

Possible Side Effects

While most patients tolerate Xolair for food allergies well, some notice mild side effects like:

• Injection site swelling
• Headaches
• Fatigue

Severe reactions are rare, but your healthcare provider will monitor you closely during your first few injections to ensure everything goes smoothly.

Is Xolair the Best Treatment for Food Allergies?

Xolair may be a suitable option if:

• You or your child is 1 year or older
• You have confirmed IgE-mediated food allergies
• You are allergic to multiple foods
• You’ve experienced severe reactions in the past
• You feel anxious about accidental exposures
