Brief Summary
WHO recommend to divide AR into 4 subgroups according to the symptom frequency (intermittent or persistent) and severity (mild or moderate-to-severe). For the persistent moderate-to-severe AR subgroup, the guideline suggests to treat with intranasal corticosteroid (INS) plus antihistamines (AH1) for 2-4 weeks. If the symptom is controlled then degrade the treatment (usually with INS) and maintenance for more than 4 weeks. However, up to 70% of patients suffering from AR do not follow treatment recommendation, they stopped medication when they feel better. This behavior always leads to uncontrolled AR, which has been identified as a high-risk factor of induction and exacerbation of asthma and chronic rhinosinusitis. A recent survey showed that AR patients prefer to an on-demand treatment rather than continuous treatment. In general, poor adherence is always a considerable issue for all long-term treatments. Previous studies have shown that as dosing frequency increases, the adherence rate decreases. Thus, less medication frequency is an important factor to optimize the management of chronic diseases including AR. Intranasal AH1 can relieve AR symptoms including sneezing, rhinorrhea and nasal itching in 3 to 5 minutes, while INS can inhibit the underlying mucous allergic inflammation and is recommended as the first-line medication for moderate-to-severe AR. INS combined AH1 have shown a synergic effect on control AR inflammation and provide rapid AR symptom relief. Investigators hypothesis that the on-demand administration of INS combined AH1 can achieve similar AR control level with less dosing frequency as compared to the daily INS maintenance in controlled moderate-to-severe AR patients.

Outcome Measures
Primary Outcomes (1)
AR control level after 4-week treatment among the three groups with different treatment
The efficacy and safety of on-demand INS (Fluticasone) combined with nasal spray AH1(Azelastine), on-demand INS and INS maintenance therapy were evaluated and compared by recording the daily symptom score and adverse events. The primary endpoint is the AR control level after 4-week treatment.
