A 10-year-old boy with ADHD is started on methylphenidate. He develops significant anorexia, insomnia, and his parents note he appears slightly sad. The appropriate management of methylphenidate-associated appetite suppression is:
- A Switch to atomoxetine immediately
- B Administer dose after meals; allow late-evening calorie-dense snack; consider a drug holiday on weekends ✓
- C Discontinue methylphenidate and start behavioral therapy only
- D Add cyproheptadine as an appetite stimulant and continue methylphenidate unchanged
Correct answer: B. Administer dose after meals; allow late-evening calorie-dense snack; consider a drug holiday on weekends
Explanation
Appetite suppression is the most common side effect of methylphenidate (a stimulant). Practical management strategies include: giving the dose after breakfast, allowing a healthy snack after drug effect wears off in the evening, and considering weekend/vacation drug holidays when academic demands are low. Cyproheptadine is sometimes used but is not a guideline-recommended first step. Immediate switch to atomoxetine is unwarranted for manageable side effects. Drug-free behavioral therapy alone is inadequate for moderate-severe ADHD.
