“Allergy shots” or allergy desensitization is a form of desensitizing a patient with allergic disease to their allergen causing their illness. These injections work by influencing your immune system slowly to become tolerant of your known allergy(ies). They are indicated for the treatment of allergic nasal conditions, i.e. hayfever, insect sting allergy and in some mild cases of asthma. There are various types and protocols for administering these injections. The medical terminology for allergen shots is SubCutaneousallergenImmunoTherapy or SCIT.
