Montelukast

Excellent choice! Montelukast is particularly effective at managing asthma triggered by allergens, occupational irritants, and exercise-induced bronchoconstriction—all of which are key contributors to Amy’s current worsening symptoms. Additionally, montelukast provides extra benefit for patients with coexisting allergic rhinitis, which Amy experiences (seasonal congestion, sneezing, watery eyes during spring).
