Patients were given oral paroxetine/placebo 10 mg for one week pre-interferon treatment, paroxetine/placebo 20 mg during the first week of interferon treatment, and then paroxetine/placebo 20 to 40 mg for all subsequent weeks of interferon therapy. Total length of treatment with paroxetine was 12 weeks. The study was based on the hypothesis that, as a selective serotonin reuptake inhibitor (SSRI), paroxetine may improve the neuropsychiatric and neurovegetative symptoms associated with interferon-alpha treatment.
Patients were undergoing the active treatment phase of care.
The study was a randomized, double-blind, placebo-controlled trial.
Neurotoxicity Rating Scale (NRS) was used to measure various depressive symptoms, cognitive disturbances, and vegetative symptoms, including fatigue.
When compared with the control group, pretreatment with paroxetine was effective in preventing interferon-induced mood and cognitive symptoms, as well improving pain. Paroxetine had less effect on the development of interferon-alpha–related neurovegetative symptoms, including fatigue, as measured by the NRS. Fatigue and somatic symptoms increased in both depressed and nondepressed patients.
Across the twelve weeks of the study, seven patients from the placebo group and one patient from the paroxetine group withdrew due to severe depression or neurotoxicity.
