Which corticosteroid is most commonly taken for asthma?

• A. Flovent
• B. Flonase
• C. Nasonex
• D. Qvar

Answer: (A)

Inhaled corticosteroids are the mainstay for long-term control of persistent asthma because they target airway inflammation directly with fewer systemic effects than oral steroids. Among the options, Flovent, which contains fluticasone, is a widely prescribed inhaled corticosteroid for daily maintenance therapy to prevent symptoms and exacerbations. That makes it the most commonly used choice for asthma in everyday practice.

Flonase and Nasonex are intranasal corticosteroids used for allergic rhinitis and not for asthma control, so they don’t address the asthma condition itself. Qvar is another inhaled corticosteroid used for asthma, but Flovent is more commonly prescribed overall, which is why it’s the best answer here.
