Sublingual Immunotherapy (SLIT)

What is Sublingual Immunotherapy (SLIT)?

Sublingual immunotherapy (SLIT), also called allergy drops, works similarly to allergy shots/injections by gradually helping your body build tolerance to the substance(s) causing your allergies. The difference is that the antigen is placed under your tongue in a liquid drop form instead of an injection

The area under the tongue has the highest concentration of antigen/allergen presenting cells found anywhere in the body. This cell, called the dendritic cell, is the messenger that delivers antigens to the cells that enable allergic tolerance. By consistently delivering allergy drops to this cell daily, the body learns to tolerate things that cause allergic reactions.
