Discontinuing Strattera (Atomoxetine) 40mg Daily
Atomoxetine can be discontinued abruptly without tapering, as it does not require a gradual dose reduction. 1
Key Discontinuation Guidance
The FDA-approved prescribing information explicitly states that "Atomoxetine capsules can be discontinued without being tapered." 1 This is fundamentally different from many other psychiatric medications that require gradual dose reduction.
Clinical Considerations When Stopping
Monitoring After Discontinuation
- Symptom rebound assessment: While atomoxetine discontinuation does not cause withdrawal symptoms, ADHD symptoms will return as the medication effect wears off 2
- Timeline for symptom return: Monitor for return of inattention, hyperactivity, or impulsivity over the first 1-2 weeks after stopping 2
- Discontinuation is well tolerated: Research shows a low incidence of discontinuation-emergent adverse events with atomoxetine 2
Important Distinctions from Other Medications
Unlike SSRIs (which can cause discontinuation syndrome with dizziness, nausea, and sensory disturbances) 3 or benzodiazepines (which require slow tapering to avoid withdrawal) 3, atomoxetine does not produce physiological withdrawal or discontinuation syndromes 1, 2.
Practical Implementation
- Simply stop the medication: No dose reduction schedule is needed 1
- Patient counseling: Inform the patient that ADHD symptoms will gradually return but no withdrawal symptoms should occur 2
- Follow-up timing: Schedule reassessment within 2-4 weeks to evaluate symptom status and discuss alternative treatment if needed 3
Common Pitfall to Avoid
Do not confuse atomoxetine discontinuation with SSRI or stimulant discontinuation protocols. The absence of required tapering is a unique pharmacological property of atomoxetine related to its mechanism as a selective norepinephrine reuptake inhibitor without significant receptor binding 2, 4.
