Sublingual immunotherapy (SLIT) is allergy vaccination administered as droplets under the tongue, absorbed through the oral mucosa. Studies confirm that sublingual immunotherapy generally relieves symptoms while reducing the patient’s consumption of symptom relieving medication.
The use of SLIT products is rapidly rising and their acceptance is largely related to convenience and a good tolerability profile, enabling patients to treat themselves at home and avoid the regular doctor’s appointments required for injection-based allergy vaccination.
