Montelukast Treatment Considerations

Introduction to Montelukast Therapy

  • The American College of Physicians recommends intranasal corticosteroids over montelukast for initial treatment of allergic rhinitis, due to superior efficacy in reducing symptoms 1, 2
  • Montelukast may be considered for patients with concurrent asthma and allergic rhinitis, as it addresses both conditions simultaneously, though it remains suboptimal as monotherapy for either condition 3

Patient Selection for Montelukast

  • Patients who refuse or cannot tolerate intranasal corticosteroids may use montelukast as an alternative, despite its lesser efficacy 1, 5
  • Montelukast can be used as add-on therapy when intranasal corticosteroids alone provide inadequate control 3

Montelukast Pharmacokinetics and Administration

  • Clinical benefits of montelukast begin by the second day of daily treatment, providing continuous control rather than acute symptom relief 4
