Switch medication from fluoxetine to clomipramine.[1] [2]
- Gradually reduce dosage of fluoxetine to a maximum of 20 mg/ day, when this dosage is > 20 mg/day.
- When a dosage of 20 mg/day is reached, stop administration.
Caution is necessary for at least four weeks.
- Day 1: start administration of clomipramine in a low dosage of 25 mg/day.
- Day 8: increase dosage of clomipramine to 50 mg/day.
- Day 28: gradually increase dosage of clomipramine to 75 mg/day and more.
- Fluoxetine slows the metabolism of clomipramine via CYP2D6.
- Desmethylfluoxetine has a halflife of at least 1 week: it takes therefore 1 month for elemination.
- Start low, go slow for clomipramine.
