Do allergy shots help seasonal allergies more than antihistamines and nasal steroids?
Abstract
Multiple randomized controlled trials (RCTs) demonstrate the effectiveness of both allergen immunotherapy and antihistamines, with or without nasal steroids, in the treatment of seasonal allergic rhinitis (strength of recommendation [SOR]: A). No RCTs directly compare immunotherapy with conservative management. Treatment decisions are driven by the clinical presentation, patient and physician preferences, practice guidelines, and expert opinion (SOR: C, based on expert opinion). In standard practice, immunotherapy is not recommended for most patients with seasonal allergic rhinitis.
