Answer of the Day

According to the results of a randomized controlled trial involving 33 patients with cannabinoid hyperemesis syndrome, haloperidol (0.05 mg/kg or 0.1 mg/kg) was superior to odansetron 8mg for average reduction from baseline in abdominal pain and nausea at 2 hours, and was associated with the need for fewer rescue antiemetics and shorter time to ED departure. In this study, there were 2 haloperidol and 6 ondansetron return ED visits for ongoing nausea/vomiting, as well as 2 return visits for acute dystonia, both in the higher dose haloperidol group.
