Azelastine Nasal Spray for Episodic Rhinitis

Introduction to Azelastine

Azelastine nasal spray can be prescribed as needed for episodic rhinitis symptoms due to its rapid onset of action within 15-30 minutes, making it suitable for patients with intermittent or episodic allergic rhinitis 1, 2, 3

The American Academy of Allergy, Asthma, and Immunology recommends intranasal antihistamines, such as azelastine, for PRN use in episodic allergic rhinitis due to their rapid onset of action 1, 2, 3
Azelastine demonstrates a therapeutic effect within 15-30 minutes of administration, which is faster than oral antihistamines and intranasal corticosteroids 1, 4
The American Academy of Otolaryngology-Head and Neck Surgery recommends azelastine as especially useful in patients with episodic nasal symptoms or as a pretreatment prior to nasal allergen exposure due to its rapid onset and targeted delivery 5, 6

Azelastine is effective for all nasal symptoms, including rhinorrhea, sneezing, nasal itching, and nasal congestion, making it suitable for patients with mixed rhinitis 1, 2, 4
Azelastine has equal or superior efficacy to oral second-generation antihistamines, but less effective than intranasal corticosteroids for continuous use 1, 2

The most common adverse effect of azelastine is bitter taste, occurring in 8-20% of patients, while somnolence rates are low, comparable to placebo 5, 6, 4
Patients should be monitored for somnolence at initiation, particularly those operating machinery or driving 4

Azelastine can be prescribed PRN for patients with episodic or intermittent rhinitis symptoms, requiring rapid symptom relief, or needing pretreatment before known allergen exposure 1, 2, 5
Scheduled twice-daily dosing should be considered instead for patients with persistent daily symptoms requiring continuous control 5, 6
