Medication Adherence to Intranasal Corticosteroids in Allergic Rhinitis Patients with Comorbid Medical Conditions.

Patients having AR with severe nasal symptoms at first presentation, who are sensitized to DP HDM and who have elevated total serum IgE levels have a higher adherence to INCS use. The use of multiple medicines had no impact on the adherence to INCS. As a lack of symptoms was a barrier towards adherence, the benefits of using INCS according to the prescribed dose and frequency must be emphasized to patients with mild and moderate AR at each medical visit. A good rapport between patients and their health care providers is needed to build trust and overcome the barriers, particularly to allay the fears of adverse effects of INCS. The other barriers, such as running out of supply, can be overcome by posting medications directly to patients by the healthcare providers.
