Allergy immunotherapy helps retrain your immune system to become less sensitive to common allergens, offering long-term relief from persistent seasonal or environmental allergy symptoms.
How is Allergic Immunotherapy Performed?
The two most common methods of allergic immunotherapy are:
- Sublingual Immunotherapy (SLIT): Sublingual immunotherapy consists of allergens that are given either as liquid drops—placed under the tongue—or in the form of allergy tablets. It may sometimes be referred to as an oral vaccine.
- Subcutaneous Injection Immunotherapy (SCIT): Subcutaneous immunotherapy, also commonly referred to as allergy shots, is an injection given subcutaneously with a small needle. You'll receive multiple injections over a period of several weeks with a gradual buildup of allergen—this helps your immune system get used to the allergen and, as a result, make it less reactive when exposed to the allergen in question.
In order for allergic immunotherapy to be successful, you will be required to take the allergen either sublingually or subcutaneously for a three to five-year duration or longer, based on your doctor's recommendation.
