Allergen-specific subcutaneous immunotherapy (SCIT) can cause IgE-mediated anaphylaxis. Allergy injections are a common trigger for anaphylaxis. This is not unexpected, because the treatment is based on injecting an allergen to which the patient is sensitive. However, life-threatening reactions are rare. Three studies suggest that fatalities from SCIT occur at a rate of approximately 1 death per 2,500,000 injections. [20, 21, 22] A total of 104 fatalities due to SCIT and skin testing were reported from 1945-2001.
