Allergic rhinitis (AR) is one of the most common types of allergy worldwide. It has significant negative impact on the quality of life (QOL). One of the available causal treatments of AR is allergen specific immunotherapy which remains effective even after the end of treatment course, unlike symptomatic drugs. AR patients aged above five years, allergic to unavoidable allergen like house dust, mite etc., and refractory to maximal pharmacotherapy were included in present study. Patients allergic to avoidable allergen, taking beta-blocker medication, having other immunological disease, and who were pregnant, breast-feeding or lost to follow up, were excluded from the study. All patients included in the study underwent sublingual immunotherapy (SLIT). The impact of treatment is measured by calculating the difference between SNOT-20 score before and after treatment (which is 6 months interval). Total 30 patients were studied. Paired-t test calculated value of cumulative score and nasal symptom score are 7.853 and 6.85 respectively. Both are greater than table value of 2.46. So paired-t test shows that SLIT is very much effective in treatment of AR. The present study re-establish the fact that SLIT not only reduces AR symptoms, it also improves the QOL. It has very good patient compliance with minimal side effects.
