In asthma management, when should inhaled corticosteroids be used?

• A. To treat acute bronchospasm only
• B. As a long-term controller when rescue therapy is insufficient.
• C. For antibiotic prophylaxis
• D. For relief during exercise only

Answer: (B)

Inhaled corticosteroids are used as long-term anti-inflammatory controllers to reduce airway swelling and hyperresponsiveness, which helps prevent daily symptoms and flare-ups. They’re not a quick-relief medication for acute bronchospasm—that role belongs to short-acting bronchodilators. Because inflammation underlies persistent asthma, ICS are taken regularly as part of maintenance therapy, especially when using rescue inhalers frequently or when symptoms aren’t adequately controlled by rescue therapy alone. They don’t work right away; it may take weeks to notice the full benefit, so consistency is key even when you feel well. They’re not for antibiotic prophylaxis, and while management may include exercise precautions, ICS aren’t used only during exercise or solely for that purpose.
