The immune system is a network of cell types working together to defend and protect the body from “invaders” such as viruses, infections and disease. If you suffer from allergies, your body’s immune system may overreact to certain allergens*. Or, if you have an immunodeficiency disorder, your body’s immune system is compromised and has difficulty fighting infections.
The concept behind immunotherapy (allergy shots) is that the immune system can be desensitized to specific allergens that trigger allergy symptoms. The allergen(s) are identified through a combination of a medical evaluation performed by a trained allergist, and an allergy diagnostic testing (skin or allergy blood tests).
Allergy immunotherapy is a proven effective treatment for allergic rhinitis, allergic asthma and stinging insect allergy. It also may be effective in some individuals with atopic dermatitis (eczema) if they have allergies to airborne allergens. Currently, immunotherapy for food allergies* is not recommended and strict avoidance of the food is advised although investigations with oral desensitization for food allergies are in progress in the United States. Immunotherapy can potentially lead to lasting remission of allergy symptoms, and it may play a preventive role in the development of asthma and new allergies.
You might benefit from immunotherapy to help build up a tolerance to your offending triggers. Sublingual Immunotherapy (also known as Allergy Tablets) or Liquid Drops Formulations are offered to some patients who suffer from allergies to short ragweed and some grass pollen. The tablets or drops will increase tolerance to the pollen and reduce symptoms over time. For continued effectiveness, treatment may be needed for three years or longer.
Sublingual Immunotherapy, commonly known as Allergy drops, are a method of treating allergies by placing drops underneath the tongue: a small dose of an allergen being introduced into the patient allows the body to build immunity over time. A dropper of antigens is placed under the tongue daily until the patient doesn’t experience any reactions anymore. They can be used for a wide variety of allergies in most patients from infants to adults.
