"FDA Greenlights First Drug for Preventing Allergic Reactions to Multiple Foods"

The FDA has approved Xolair (omalizumab) injection for reducing allergic reactions, including anaphylaxis, from accidental exposure to multiple foods in certain adults and children with immunoglobulin E-mediated food allergy. Xolair, originally approved for allergic asthma, is the first medication to reduce allergic reactions to more than one type of food after accidental exposure. Its safety and efficacy were established in a study of subjects allergic to peanut and at least two other foods. Common side effects include injection site reactions and fever, and Xolair comes with warnings for anaphylaxis and other potential adverse effects.
