Abstract

Clozapine is a crucial antipsychotic medication to treat schizophrenia and has shown valuable benefits in doing so. However, there can be rare, but potentially fatal adverse drug reactions to the medication. Therefore, it is essential that there is careful monitoring of the patient while on the medication. A retrospective study was conducted to examine the effects of clozapine on vitals during the first 2 days of initiation. There were 43 (29 male, 16 female) charts analyzed retrospectively, and the average age of the patients was 45 years old. The average dose of clozapine on the first day was 9.3mg and 15.7mg on the second day. Regarding vitals, the temperature peaked 5 hours after administrating clozapine on day 1 and day 2. Furthermore, the respiration rate peaked 4 hours post-dose on the second day and the heart rate increased the most on the second day indicating a dose-related response. There was no trend in blood pressure changes that can be inferred from the data; however, individual variations in blood pressure fluctuated considerably. The study was limited due to a lack of data in patient charts, and it may be of interest to do a prospective study to gain more insight.
