A patient is prescribed both an inhaled bronchodilator and an inhaled corticosteroid for asthma. Which instruction is generally appropriate when both are used at the same time?
Correct answer: B. Use the bronchodilator first, then the corticosteroid
- A. Use the corticosteroid first to close the airways briefly
- B. Use the bronchodilator first, then the corticosteroid
- C. Mix both medicines in the same inhaler chamber
- D. Use only the corticosteroid during an acute severe attack
Explanation
The bronchodilator opens the airways and can improve delivery of the inhaled corticosteroid. The corticosteroid controls inflammation but is not the medicine for rapid relief during an acute severe attack.
