Persistence of treatment with 5-grass pollen tablets in patients with allergic rhinitis: a real-life study.

Background: In patients with allergic rhinitis, treatment adherence to allergen immunotherapy varies greatly in randomized and real-life studies.

Objective: To evaluate the use of a 5-grass pollen tablet as sublingual immunotherapy, its treatment persistence, and the reasons for discontinuation in a real-life clinical setting.

Methods: This multicenter, prospective, open-label, noncontrolled observational study evaluated the use of sublingual immunotherapy with a 5-grass pollen tablet in a cross-sectional population of patients (≥5 years old) with grass pollen-induced allergic rhinitis with or without asthma.
