The prevalence of tardive dyskinesia in fluphenazine-treated patients
1Douglas Hospital Centre, Verdun, Québec, Canada.
Abstract:
One hundred thirty-five outpatients were evaluated for tardive dyskinesia (TD). Of the fluphenazine-treated patients (N = 63), 32 were found to have TD as compared with 29 of 72 non-fluphenazine-treated patients. This difference was not statistically significant. There was no difference in duration and total dose of fluphenazine injections between TD and non-TD patients. However, patients receiving fluphenazine injections were found to require fewer hospitalizations after fluphenazine therapy was started.
