Omalizumab is a monoclonal antibody directed against IgE that plays a role in the release of inflammatory mediators from mast cells and basophils. It is currently only approved for allergy-mediated asthma but is being used off-label to treat other allergic symptoms. Diphenhydramine, fexofenadine/pseudoephedrine, and guaifenesin are not used to treat asthma.
