A short-cut review was carried out to establish whether haloperidol is effective at treating the symptoms of cannabinoid hyperemesis syndrome (CHS). One study was directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of that paper were tabulated. The clinical bottom line was that no controlled studies exist to report on the use of haloperidol. Alternative agents, used mainly off-label, show better promise at effectively treating symptoms of CHS based on case series and reports.
