Montelukast Treatment Guidelines

Efficacy and Indications

The American College of Allergy, Asthma, and Immunology states that intranasal corticosteroids are more effective than montelukast for allergic rhinitis and should be first-line treatment 1, 2, 3
Montelukast has similar efficacy to oral antihistamines but is less effective than intranasal corticosteroids 2
For asthma, inhaled corticosteroids remain the preferred long-term control medication over leukotriene receptor antagonists 3
The American Academy of Allergy, Asthma, and Immunology recommends montelukast for patients with both allergic rhinitis and asthma, as it can manage both conditions simultaneously 2

The FDA recommends explicitly counseling parents and patients about serious neuropsychiatric risks, including suicidal thoughts, depression, anxiety, sleep disturbances, and behavioral changes before prescribing 3
Monitor for unusual behavioral or mood changes, particularly in the first weeks of therapy 3
Never use montelukast for acute asthma exacerbations or as rescue therapy—always ensure a short-acting beta-agonist is available for acute symptoms 3
Do not discontinue montelukast when symptoms improve; it provides continuous control and must be taken daily 3
Onset of action is typically on the second day of treatment, unlike antihistamines which work quickly 2
