Allergen Immunotherapies: What's the Difference?


I came across an article referencing OMIT as another experimental therapy for food allergy.  There are several types of immunotherapies (Its) out there for both food allergies and airborne allergies and most, if not all, are still in clinical trials for the treatment of food allergies.  Here is a quick run down for those that are unsure of the difference.  All involve introducing an escalating dose of allergen to the body in order to build tolerance.

OIT is Oral Immunotherapy and is done by swallowing the allergen in small doses.  Read more here.

SLIT is sublingual immunotherapy and is done by placing liquid drops or tablets under the tongue for a set amount of time. Read more here.

SCIT is subcutaneous immunotherapy is done by injecting the allergen into the body. Read more here.

EPIT is epicutaneous immunotherapy and is done by placing a patch with allergen dose onto the skin.  More information on this treatment here. 

OMIT is oral mucosal immunotherapy and is done by infusing a toothpaste with allergen dose to be applied during tooth brushing.  More information on this treatment here.
