What are allergy shots/injections/immunotherapy?
Allergy immunotherapy is one of the modalities of treatment for allergies and asthma. It consists of a series of injections given initially once or twice a week during the build-up phase and once every 2-4 weeks during the maintenance phase. It modifies the immune system so that it is better able to deal with the allergens. It usually lasts 3-5 years. It has been proven to be effective for allergies, allergic asthma and insect sting reactions but not for foods. The injections are given under the skin (subcutaneously).
