Switch medication from fluoxetine to escitalopram.[1] [2]
Stop fluoxetine - Reduce the dosage to 20mg/day and then stop the administration
Start escitalopram- No wash-out period is needed.
- Day 1: start escitalopram the next day in low dosage of 5 mg/day.
- Day 14: increase dosage of escitalopram to normal, i.e. 10 mg/day.
More information- Fluoxetine has a very long elimination time; phasing out fluoxetine is therefore not necessary.
- Occurrence of the serotonin syndrome is not likely, but theoretically possible, so caution is necessary.
- Fluoxetine inhibits CYP2C19, CYP2D6 and CYP3A4, which metabolize escitalopram.
- This switch is currently being reviewed.
- ↑ Switches are based on literature references on this page and expert opinions of the authors. The authors have used pharmacokinetic and receptor affinity properties to determine the switch schedules
