ENT Surgical Consultants is Chicagoland’s premier SLIT center. Allergy drop treatment works similar to allergy shots by delivering a slowly increasing dose of physician-prescribed antigen that, over time, builds the body’s tolerance. The difference is that the drops are placed under the tongue and affect the immune system through very specialized cells found under the tongue. Research shows that SLIT is equally effective as shots. Allergy drops are administered at home by the patient. No more coming into the office for weekly appointments!
