Compazine has been shown to cause orthostatic hypotension and extrapyramidal symptoms. Of the extrapyramidal symptoms, akathisia (25-60% after single dose) and dystonic reactions (4% after single dose) are the most commonly encountered. These reactions can be minimized by the rate of administration and the concurrent use of diphenhydramine. Due to the study design, diphenhydramine will not be used but a slow rate of administration with 50 ml normal saline bag that will be given over 5 minutes. This slower rate of administration will decrease risk of extrapyramidal symptoms. Irreversible tardive dyskinesia and neuroleptic malignant syndrome have been described with compazine. These complications are extremely rare and the true incidence is unknown
