How to Taper Buspirone 15 mg BID
Buspirone can be tapered gradually by reducing the dose by 5 mg every 1-2 weeks, though unlike benzodiazepines, buspirone does not typically cause withdrawal symptoms and can be discontinued more rapidly if needed.
Tapering Strategy
The FDA labeling for buspirone does not specify mandatory tapering requirements 1. Unlike benzodiazepines or SSRIs, buspirone has a favorable discontinuation profile. Research demonstrates that abrupt discontinuation of buspirone after more than 6 months of therapy yielded no evidence of withdrawal syndrome or unusual events 2.
Recommended Taper Schedule
For your 15 mg BID (30 mg/day total) regimen:
Week 1-2: Reduce to 10 mg BID (20 mg/day total)
- Use the scored 15 mg tablets bisected to provide 10 mg doses 1
Week 3-4: Reduce to 5 mg BID (10 mg/day total)
- Use the scored 10 mg tablets bisected to provide 5 mg doses 1
Week 5-6: Reduce to 5 mg once daily
Week 7: Discontinue
Important Considerations
Avoid alternate-day dosing. While some clinicians recommend every-other-day dosing when tapering, recent evidence shows this approach causes pronounced receptor occupancy variation and increases withdrawal risk with psychotropic medications 3. Maintain daily dosing throughout the taper with progressively smaller doses.
Monitoring Plan
While buspirone lacks significant withdrawal symptoms, monitor for:
- Return of anxiety symptoms (may take weeks to manifest) 4
- The original indication for treatment should guide monitoring duration
- Unlike ADHD stimulants where symptom return occurs in hours to days, anxiety disorders may show delayed symptom recurrence 4
Faster Discontinuation Option
Given the absence of withdrawal syndrome in clinical studies 2, if clinical circumstances require faster discontinuation, buspirone can be stopped more abruptly than the gradual taper outlined above. This is particularly relevant if the medication is ineffective or causing adverse effects.
Clinical Context
Buspirone is typically dosed at 15-30 mg/day for maintenance treatment 2, so your current 30 mg/day dose is at the upper end of the typical range. The gradual taper allows assessment of whether anxiety symptoms return at lower doses, which may indicate ongoing need for treatment 4.
