SECTION - Medications
POLICY NUMBER: 510
Effective Date: August 31, 2006
SUBJECT: CARE OF THE INDIVIDUAL RECEIVING CLOZAPINE
Clozapine is indicated for the severely ill schizophrenic Individual who has not responded to other neuroleptic medication or who is experiencing intolerable side effects from current medication. During the stabilization, period Individuals will be titrated up from an initial low dose. Because of potentially severe blood dyscrasias, Pharmacy will only distribute unit dose supplies based on mandatory weekly or bi-weekly white blood counts (WBCs).
Due to the effect of clozapine on the GI tract, special consideration must be given when assessing the Individual for potential or actual constipation. A Individual may be constipated or have a partial impaction with no symptoms, or subtle symptoms. Nursing is required to assess any change in Individual status that may indicate constipation or formation of an impaction. The following changes in a Individual’s status can indicate the beginning of an impaction: changes in mental status (e.g. confusion, delirium); an increase in the Individual’s presenting psychiatric or psychotic symptoms; physical changes such as bloating, discomfort or pain in the abdomen or rectum. If changes are found upon assessment, the change in status must be referred to the physician immediately. Though some Individuals on clozapine have had no difficulty with constipation, each Individual will be monitored by eliminative subsystem each shift.
