sublingual immunotherapy

Abbreviation: SLIT
Allergen desensitization in which the antigen is administered in droplet form under the tongue instead of being injected subcutaneously. SLIT is a relatively safe form of immunotherapy and is often used at home instead of in a medical office, several times a week.

Patient care

Adverse effects include oral itching or swelling and gastrointestinal upset. The incidence of systemic side effects may be reduced with SLIT as opposed to immunotherapy by subcutaneous injection.
