Strattera (atomoxetine) begins to work in the body from the first dose, but it typically takes about 4 to 8 weeks for most people to see a noticeable improvement in ADHD symptoms. Some individuals might start to experience mild symptom changes within 1 to 2 weeks, and in some cases, it could take up to 12 weeks or longer for the full effects to be reached. The response time can vary from person to person, and it also depends on finding the right dosage. Strattera works gradually by increasing norepinephrine levels in the brain to help improve attention and focus. In summary:
- Starts working in the body right away.
- Noticeable symptom improvement usually takes 4 to 8 weeks.
- Full effects might take up to 12 weeks or more.
- Some people see mild improvement within 1 to 2 weeks.
- Response varies individually and with dosage adjustment.
