Sections Modified Summary of Changes to Contraindications and Warnings

WARNINGS

  • Tardive Dyskinesia

ADVERSE REACTIONS

  • Extrapyramidal Symptoms
    • Dystonia
      • Class Effect

Class Effect: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups. Clozapine, an atypical antipsychotic, is associated with a low incidence of dystonia [See Warnings, Tardive Dyskinesia].

WARNINGS

Tardive Dyskinesia

There are several reasons for predicting that FazaClo may be different from other antipsychotic drugs in its potential for inducing tardive dyskinesia, including the preclinical finding that it has a relatively weak dopamine-blocking effect and the clinical finding of a low incidence of certain acute extrapyramidal symptoms, e.g., dystonia.
