Allergy shots

An allergy shot injects medicine into your body, which contains a small amount of substance (allergen) that triggers your allergic reaction. The purpose of the allergen is to create a level of desensitization in the body and alter your immune system's tolerance to the allergen. Allergens in the shots are tailored to your specific allergies.

You should experience improvements to some or all of your symptoms caused by allergens within six to 12 months. Improvement can be permanent after a course of three to five years.

Allergy shots are only one part of an allergy treatment plan. Your provider may also ask you to take allergy medicines and reduce your exposure to allergens.
