Food Allergy Treatment: How Xolair Offers New Hope for Allergies

Understanding Food Allergies

Food allergies occur when the immune system mistakenly identifies a harmless food protein as a threat, causing an immune response. This reaction releases chemicals like histamine, leading to symptoms ranging from mild discomfort to severe reactions. Common food allergens include peanuts, shellfish, milk, eggs, and wheat.

Xolair: A Promising Treatment

Xolair, initially targeting asthma and chronic spontaneous urticaria, has recently become the first FDA-approved medication to reduce the risk of severe allergic reactions to multiple foods. It is crucial to note that while Xolair may not cure food allergies, it significantly lowers the severity of reactions after accidental exposure. Clinical trials suggest efficacy in reducing reactions to allergens such as peanuts, cashews, and eggs.

Side Effects and Accessibility of Xolair

Xolair may cause side effects, including fever, dizziness, and fatigue, while more severe reactions like anaphylaxis are rare. In India, Xolair's high cost and limited availability pose challenges for broader access. Nonetheless, more affordable biosimilars like Emzumab have emerged.

Alternative Treatments and Self-Management

Avoiding known allergens remains the best strategy. Practices like checking ingredient lists and alerting restaurant staff about allergies are essential. Oral immunotherapy shows promise in building tolerance to allergens over time. Additionally, carrying an epinephrine auto-injector is vital for emergency situations.
