Question 1 of 5
What is the most important serious side effect that parents should be warned about before commencing atomoxetine?
Correct Answer: D
Rationale: Atomoxetine is a non-stimulant medication for ADHD. Suicidal ideation (Choice D) is a critical side effect, with a black box warning from the FDA due to increased risk in children and adolescents, necessitating parental awareness. Cardiac toxicity (Choice A) is rare and less emphasized compared to stimulants. Depression (Choice B) can occur but isn’t the primary concern. Potential for abuse (Choice C) is negligible as atomoxetine lacks stimulant properties. Suicidal ideation’s severity and regulatory emphasis make it the most important warning.
