Are allergy shots effective in preventing or decreasing food allergy?
Allergy shots, a form of treatment known as immunotherapy, involve injecting small quantities of substances to which the patient is allergic. The shots are given regularly for a long time with the aim of desensitizing the patient or getting the patient to tolerate the allergen without developing symptoms. This type of therapy is effective in controlling symptoms of allergies related to hay fever, indoor allergens, and insect stings. Researchers, however, have not yet proven that these shots can prevent any allergic reactions to food.
