caused by antipsychotic medication may improve with time, is reversible when medication is lowered or stopped, and may be treated with anticholinergic medication.
Note symptoms associated with antipsychotics (ie, iatrogenic morbidity), such as the restlessness with akathisia, tremor and bradykinesia with pseudoparkinsonism
, and irregular abnormal movements with tardive dyskinesia.
In addition, benzodiazepines may be considered for akathisia, anticholinergic agents for the coarse resting tremor of pseudoparkinsonism
, and beta-blockers for the fine intention tremor associated with SSRIs and SNRIs.
To control the pseudoparkinsonism symptoms, the patient takes trihexyphenidyl orally 5 mg bid.
