Does inhaling isopropyl alcohol reduce nausea?

BEEM Bottom Line

Why is this study important?

Nausea and vomiting is a common presentation to the emergency department (ED). Inhaled isopropyl alcohol (IPA) is inexpensive and readily available and can be used without intravenous access. Additionally, a recent systematic review revealed that IPA effectively reduced nausea and vomiting compared to placebo in postoperative patients, although it is not superior to traditional antiemetics.[1]
