Strattera (atomoxetine) typically takes about 4 to 8 weeks for patients to notice a significant improvement in ADHD symptoms; some individuals may begin to experience symptoms relief within 2 weeks, but the full effects can be reached in 8-12 weeks, and improvements may continue for up to 24 weeks or longer (Medical News Today, 2023; Drugs.com, 2023; Healthline, 2023).
