Xolair (omalizumab) is an anti IgE medication that works by inhibiting the allergic reaction process. It is FDA approved for use in children over age 6 with asthma and in children over age 12 with chronic urticaria (hives). At Latitude, we offer Xolair in conjunction with OIT to increase safety for some patients over age 4. While this injectable biologic has been granted Breakthrough Therapy Designation for the prevention of severe allergic reactions to food allergy by the FDA, it is still an “off label” usage and may not be covered by insurance. If our allergist prescribes this medication for you, we can work with you and your insurance plan to help understand the out-of-pocket costs before proceeding.
