Abstract

Purpose: Sublingual immunotherapy is currently promoted by various companies, with administration schedules variable in the different products even though almost all are standardized immunologically. So, this study was planned to examine the efficacy of simple nondaily dosing of sublingual immunotherapy instead of the widely used daily schedule.
Materials and Methods: Fifty-two patients with allergic rhinitis and bronchial asthma were enrolled. Sublingual immunotherapy (manufactured at the allergen immunotherapy preparation unit at Mansoura University) was given in suitable bottles with a dropper mechanism that permits comfortable dosing under the tongue. The physician recommended that the patient put the drops under his/her tongue and leave the drops beneath the tongue for 2 minutes before swallowing. This was repeated every 3 days, with the drop number and concentration gradually rising.
Results: After 2 months of follow-up, 65.8% responded partially to the symptom score and 26.3% responded completely to the medication score. There was a significant decline in the symptom and medication scores from the baseline scores (p<0.0001). After 4 months of follow-up, 95.8% responded partially to symptom scores and no one has not responded; 54.2% responded completely to medication scores; and 81% of studied patients had no side effects. However, the most frequent side effect was a sore throat.
Conclusion: Our nondaily schedule of sublingual immunotherapy is tolerable, safe, and effective in patients with allergic rhinitis and bronchial asthma.
