sublingual immunotherapy is a treatment for allergies that involves placing a small dose of allergens under the tongue. This method helps the immune system gradually become less sensitive to specific allergens, such as pollen or pet dander. Over time, this can reduce allergy symptoms and improve quality of life. The treatment typically starts with a low dose, which is gradually increased. Patients usually take the medication daily at home, making it a convenient option compared to traditional allergy shots. sublingual immunotherapy is considered safe and effective for many individuals with allergic rhinitis or other related conditions.
