Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies (such as insect bites) and asthma. [ 1 ] [ 2 ] Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.
Treatment can be given as an injection, tablet, sprays or sublingual drops. The gradual increase of allergen causes the immune system to become less sensitive to the substance ( desensitization ), reducing symptoms during future exposures to the allergen, and possibly preventing new allergies.
Allergen immunotherapy is the only treatment that alters the disease mechanism. [27] Immunotherapy can be administered orally (as sublingual tablets [28] or sublingual drops), or by injections under the skin (subcutaneous). [29] Subcutaneous immunotherapy is the most common form and has the largest body of evidence supporting its effectiveness ...

The mainstay of treatment for food allergy is total avoidance of the foods identified as allergens. An allergen can enter the body by consuming a portion of food containing the allergen, and can also be ingested by touching any surfaces that may have come into contact with the allergen, then touching the eyes or nose.
Intradermal injections are used. The treatment takes 3–4 weeks before any effect is seen. For food and environmental allergies and intolerances treatments are typically given at two monthly intervals at first, but the interval between treatments is gradually lengthened. Hay fever is treated with two shots of EPD outside the pollen season.
