In this observational study, 65 children were treated with SLIT with a build-up phase of 11 days, culminating in a peak dose of 300 IR, and followed by a maintenance phase of 300 IR three times weekly. There were 51 boys and 14 girls; age range was 38 to 80 months (median age, 60 months). Allergens used were house dust mites in 42 patients, grass pollen in 11, olive pollen in five, Parietaria pollen in four, and cypress pollen in three patients. Adverse reactions and changes in the treatment schedule were compared in children aged 38 to 60 months vs those aged 61 to 80 months.
