Interaction Effect
An increased risk of developing acute parkinsonism
Interaction Summary
The development of acute, severe parkinsonism has been observed in a patient receiving fluphenazine for Tourette's syndrome and sertraline for depression. Upon discontinuation of sertraline, the parkinsonism resolved. A similar interaction has been observed when fluphenazine was given in combination with fluoxetine or paroxetine.
Severity
Moderate
Onset
Delayed
Evidence
Probable
How To Manage Interaction
Patients receiving concurrent therapy with fluphenazine and sertraline should be monitored for the development of drug-induced parkinsonism. Therapy with sertraline may need to be discontinued.
Mechanism Of Interaction
Inhibition of cytochrome P450-mediated fluphenazine metabolism by sertraline
Literature Reports
A) A 45-year-old male with chronic, multiple motor and vocal tics since childhood was successfully controlled with haloperidol, but symptoms of depression emerged. Haloperidol was discontinued, and fluphenazine was instituted without an improvement in the patient's mood. Sertraline 125 mg daily was added incrementally, and the patient developed acute, severe parkinsonism after eight weeks. When fluphenazine was discontinued, the parkinsonism resolved, but the tics returned to their baseline level of severity within three weeks .
Sertraline Overview
-
Sertraline is used to treat depression, obsessive-compulsive disorder (bothersome thoughts that won't go away and the need to perform certain actions over and over), panic attacks (sudden, unexpected attacks of extreme fear and worry about these attacks), posttraumatic stress disorder (disturbing psychological symptoms that develop after a frightening experience), and social anxiety disorder (extreme fear of interacting with others or performing in front of others that interferes with normal life). It is also used to relieve the symptoms of premenstrual dysphoric disorder, including mood swings, irritability, bloating, and breast tenderness. Sertraline is in a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amounts of serotonin, a natural substance in the brain that helps maintain mental balance.
