For a patient receiving an inhaled corticosteroid, which intervention best helps prevent a common adverse effect?

• A. Rinse mouth with water after use
• B. Take the medication with a large meal
• C. Provide the client with a cup of water to rinse the mouth
• D. Use a spacer only for certain doses

Answer: (C)

Inhaled corticosteroids can leave medication in the mouth and throat, which often leads to oral candidiasis and hoarseness. Rinsing the mouth with water after each inhalation directly removes residual drug from the oropharynx, lowering the risk of these local adverse effects. Providing a cup of water for this rinse is the practical way to implement that prevention.

Using a spacer can reduce how much medication deposits in the mouth and throat, but rinsing after use is the most direct way to prevent the common local side effect. Taking the medication with a large meal won’t impact this issue.
