Reductions in nausea severity for this adult ED nausea and vomiting population were similar for 4 mg intravenous ondansetron, 20 mg intravenous metoclopramide, and placebo. It is interesting that two commonly administered medicines, one of them an expensive one, are little better than a saline infusion.
