Which instruction is most important to include when teaching about prednisone therapy?

• A. Urine may appear concentrated or reddish-orange
• B. Take the daily dose at bedtime to avoid daytime drowsiness
• C. Cover exposed skin when spending time in direct sunlight
• D. Monitor mouth sores for white patches or increased discomfort

Answer: (D)

Prednisone suppresses the immune system and can alter the body's defenses in the mouth, making infections like oral candidiasis more likely. Teaching patients to monitor mouth health—watching for white patches, redness, and increased discomfort—helps catch problems early and prevents progression. Early recognition allows timely treatment (such as antifungal therapy) and may prompt clinician guidance on continuing or adjusting therapy, which is crucial for safety.

Other cautions, like photosensitivity with sun exposure or possible insomnia if taken late in the day, are important but do not pose the same immediate risk as an oral infection and its potential complications. Urine color changes aren’t a typical or reliable predictor of prednisone-related issues, and while taking prednisone in the morning is generally advised to minimize insomnia, that instruction is less critical than recognizing and addressing mucosal infections promptly.
