Fluoxetine As An Intervention
Many doctors advise patients who are suffering from SSRI discontinuation syndrome to use fluoxetine as a substitute for their current drug. Substituting fluoxetine in the final stages of SSRI discontinuation, or post discontinuation, provides a rate of reduction of antidepressant which can minimize or eradicate withdrawal symptoms in the patient. Fluoxetine migrates slowly from the brain to the blood. The active metabolite of fluoxetine remains a long time in the brain because it is lipophilic, with a biological half-life of 4 to 8 days (the longest of any SSRI). Therefore the level of the drug in the body falls slowly at a rate to which the brain can adjust when the dosage is reduced. Fluoxetine is also available in a liquid formula, allowing the physician to titrate the drug with greater ease (e.g., with an oral syringe).
In a randomized trial, abrupt interruption of antidepressant therapy for 5–8 days was associated with the emergence of new somatic and psychological symptoms with the highest degree in patients treated with paroxetine and to a lesser degree sertraline, with few symptoms seen with fluoxetine.
- Fluoxetine for clomipramine withdrawal symptoms was reported in 1999 by F. Benazzi.
- Fluoxetine was indicated to cover serotonergic discontinuation syndromes for cessation of paroxetine associated with withdrawal or discontinuation symptoms.

Famous quotes containing the word intervention:
“All of the assumptions once made about a parent’s role have been undercut by the specialists. The psychiatric specialists, the psychological specialists, the educational specialists, all have mystified child development. They have fostered the idea that understanding children and promoting their intellectual well-being is too complex for mothers and requires the intervention of experts.”
—Elaine Heffner (20th century)
