Polypharmacy in psychiatry: three case studies and methods for prevention.
OBJECTIVE
To illustrate problems of overprescribing in the elderly and to make practical suggestions for prevention of polypharmacy.


METHODS
Three cases of polypharmacy in psychiatric patients admitted to the hospital between January and March 1990 are described. Intervention to correct drug-related problems in these patients is described and methods of preventing polypharmacy are discussed.


METHODS
Inpatient psychiatry service in a tertiary-care center.


METHODS
Elderly psychiatry patients (n = 3) taking an excessive number of medications. This polypharmacy was believed to contribute to decreased cognitive and/or physical function.


METHODS
Medication regimens were reviewed by the physician and pharmacist. Those considered unnecessary or believed to be adversely affecting the patient were discontinued.


RESULTS
All patients were discharged on a reduced number of medications, with improvement in cognitive and/or physical function.


CONCLUSIONS
Polypharmacy contributes to an increased incidence of adverse reactions in the elderly. Implementation of practical methods for reducing polypharmacy can lead to a reduction in the number of drug-related adverse effects and improved care of the elderly patient.
