For which symptoms can montelukast be administered to a child aged 6 months?

• A. Exercise-induced bronchoconstriction
• B. Asthma attacks
• C. Seasonal allergies
• D. Year-round allergies

Answer: (D)

Montelukast is a leukotriene receptor antagonist commonly used to manage asthma and allergic rhinitis symptoms. In children aged 6 months, its indication aligns with managing year-round allergies, also known as perennial allergic rhinitis. Montelukast is effective in alleviating symptoms such as nasal congestion, sneezing, and runny nose associated with allergic rhinitis.

While montelukast can be used for conditions like exercise-induced bronchoconstriction, asthma attacks, and seasonal allergies, there are specific age restrictions and clinical considerations for these conditions. For instance, the use of montelukast for asthma typically requires a diagnosis that may not be validated in very young children, as their respiratory systems are still developing. Seasonal allergies are generally less frequently prevalent in infants compared to older children. Therefore, its approval and application for year-round allergies make it the most suitable answer for a child as young as 6 months.
