J Allergy Clin Immunol 2013;132:1219-1220] documented the efficacy of the intravenous administration of ondansetron in children with acute symptoms due to food protein-induced enterocolitis syndrome (FPIES). [ncbi.nlm.nih.gov]

2 minutes through a peripheral intravenous catheter Active Comparator: Promethazine Promethazine 10 mg intravenous administration Drug: Promethazine 12.5 mg intravenous dose administered over 2 minutes through a peripheral intravenous catheter Placebo [clinicaltrials.gov]

After intravenous fluids, morphine, antibiotics, and 2 doses of ondansetron, the patient became unresponsive with agonal respirations and a wide complex tachycardia consistent with ventricular tachycardia. [ncbi.nlm.nih.gov]

Patients in adjunctive ondansetron therapy also experienced significantly lower incidence and severity of parkinsonism and akathisia as well as fewer behavioral hyperactivity, cardiac, and gastrointestinal side effects. [ncbi.nlm.nih.gov]

However, in adults, promethazine is less effective than prochlorperazine. 24 Data from adults suggest that drowsiness (38 percent) 24 and akathisia (44 percent) 25 are common adverse events. [doi.org]

Upon emergence from an uneventful general anesthetic, the patient exhibited cogwheel rigidity with decerebrate posturing and a markedly irregular respiratory rate. This prohibited extubation and prompted an unplanned intensive care unit admission. [ncbi.nlm.nih.gov]

Reported symptoms included somnolence, agitation, tachycardia, tachypnea, hypertension, flushing, mydriasis, diaphoresis, myoclonic movements, horizontal nystagmus, hyperreflexia, and seizure. [dailymed.nlm.nih.gov]

Tardive dyskinesia consists of abnormal, involuntary, irregular choreoathetoid movements of the muscles of the head, limbs, and trunk and often is irreversible (1). Several different suppressive agents have been tried with limited success (2). [ajp.psychiatryonline.org]

Tardive dyskinesia had been stable for at least 3 months before entry to the study as measured by Abnormal Involuntary Movement Scale (AIMS) (6) scores. [ajp.psychiatryonline.org]
