Switching from Escitalopram to Duloxetine
Introduction to Switching Protocol
- The Mayo Clinic recommends a cross-taper approach rather than abrupt switching to minimize withdrawal symptoms while maintaining therapeutic coverage 1
Cross-Tapering Protocol
- Start duloxetine 30mg once daily while simultaneously reducing escitalopram from 20mg to 10mg, then discontinue escitalopram after one week while increasing duloxetine to 60mg daily 1
- Reduce escitalopram from 20mg to 10mg daily during the first week of cross-tapering 1
- Discontinue escitalopram completely after one week of cross-tapering and increase duloxetine to 60mg once daily 1
Monitoring and Management
- Nausea is the most common side effect when initiating duloxetine 1
- Monitor blood pressure and pulse regularly during the transition 1
- Duloxetine can increase both blood pressure and pulse 1
Special Considerations
- Gradual tapering over 10-14 days limits withdrawal symptoms from escitalopram 2
- Consider starting duloxetine at 20mg with a slower cross-taper schedule for elderly or frail patients 1
- Duloxetine dosage may require adjustment in patients with kidney disease 1
- Avoid duloxetine in severe renal impairment 1
