The recent approval of omalizumab for the treatment of IgE-mediated food allergy is an important step forward for the millions of food allergy patients in the United States. Through the depletion of circulating IgE and the subsequent reduction of FcεR1 on key effector cells, patients increase their tolerance to food allergens. However, omalizumab does not permit patients to eat foods that they are allergic to with impunity. Rather, it protects them from most accidental exposures. In addition, omalizumab does not cure food allergy and has not demonstrated true immunomodulation. Thus, omalizumab might be a lifelong therapy for some patients. Furthermore, there are many important questions and issues surrounding the appropriate administration of omalizumab to treat food allergy, which we discuss. Managing treatment of patients with disease that falls outside the dosing range, assessing treatment response or nonresponse, addressing its appropriateness for patients older than 55, and determining whether immunotherapy plus omalizumab provides any advantage over omalizumab alone all need to be examined. Identifying appropriate patients for this therapy is critical given the cost of biologics. Indeed, not all food allergy patients are good candidates for this therapy. Also, when and how to stop omalizumab therapy in patients who may have outgrown their food allergy needs to be elucidated. Thus, although this therapy provides a good option for patients with food allergies, much information is needed to determine how best to use this therapy. Despite many unanswered questions and issues, we provide clinicians with some practical guidance on implementing this therapy in their patients.
