Brief Summary

Allergic rhinitis in children is common. According to the international study of asthma and allergies in childhood (ISAAC) phase III, the global prevalence of allergic rhinitis among children is increasing to 40.1% and the prevalence of allergic rhinitis in Bangkok area in 2018, among children aged 6-7 and 13-14 years was 16.32%. This disease is a global health problem affecting quality of life of patients in daily life, work, study and sleep. Intranasal corticosteroid is the most effective treatment for allergic rhinitis. From real world evidence; most of allergic rhinitis patient use the drug when symptoms worsen. In children, the use of intranasal corticosteroid may cause minor local side effects such as dryness, burning sensation or epistaxis. In some intranasal corticosteroid, long-term use may result in decreased growth compared to placebo which make parents concern. The investigators interested in studying the efficacy of intranasal corticosteroid comparing between daily use and as needed use in children with allergic rhinitis. To study the appropriate form of treatment to increase cooperation. Patient will have a better quality of life and reduce the risk of side effects from prolonged use of intranasal corticosteroid. From the literature review, it was found that most studies were conducted among adult patients with seasonal allergic rhinitis In Thailand in 2020, Thongngam et al. studied the efficacy of intranasal corticosteroid was compared between daily use and as needed use in adult patients with perennial allergic rhinitis. The results of the study concluded that the daily use group can reduced more TNSS (total nasal symptoms score) but was not statistically significant and had a greater increase in peak nasal inspiratory flow (PNIF) compared to as needed group. Interestingly, the quality of life assessment (RCQ-36 score) in both2 groups improved equally, In as needed group, the cumulative dose was 51% lower than the daily dose group. The investigators want to compare the efficacy of intranasal corticosteroid between daily versus as needed use in children with perennial allergic rhinitis which had not been studied before.

Outcome Measures

Primary Outcomes (2)

  • TNSS (total nasal symptoms score)

    change in TNSS 4 nose symptoms (sneezing, itching nose, watery running nose and blockage) The minimum score is 0 and maximum score is 3 each symptoms (\_\_/12) higher scores mean worse outcome.

    8 week

  • VAS score (Visual analog scale score for rhinitis)

    change in VAS score Score is 0 - 10 mm higher scores mean worse outcome.

    8 week

Secondary Outcomes (9)
