Also known as allergy shots, immunotherapy is used to treat allergic rhinitis symptoms, such as sneezing, watery eyes and runny nose, in people who suffer yearly from this allergy. During treatment, increasing, controlled doses of an allergen are injected into a patient over several months. The goal is to increase the patient's tolerance to the allergen while reducing symptoms brought on by an allergic reaction.
"Immunotherapy can lead to the long-lasting relief of allergy symptoms, and is successful in up to 90 percent of patients with hay fever," said Dr. Linda Cox, chair of the AAAAI's Immunotherapy and Allergy Diagnostics Committee. "It also has been shown to prevent the development of new allergies and it can prevent the progression of allergic diseases such as hay fever and asthma ."
Immunotherapy is also recommended for people with allergic asthma, conjunctivitis and allergies to stinging insects .
This recommendation was provided by the American Academy of Allergy, Asthma and Immunology in a press release.
