Lexapro and Adderall aren’t interchangeable. Lexapro treats depression and anxiety by adjusting serotonin and works gradually. Adderall is a stimulant for ADHD, boosting dopamine and norepinephrine with rapid effects. “Better” depends on the condition: Lexapro suits mood and anxiety disorders; Adderall suits attention and impulse control issues. They have different side effects and risks, so choice should be guided by a clinician.
