More information
- Fluoxetine and its metababolite desmethyl-fluoxetine have a very long elimination time of about 1 week; phasing out fluoxetine is therefore not necessary.
- Occurrence of the serotonin syndrome is not likely, but theoretically possible, so caution is necessary.
- Safe target dose fluvoxamine = 100 mg
