The best current evidence for treating acute pediatric cannabinoid hyperemesis syndrome suggests IV rehydration followed by low-dose haloperidol, with complete cannabis cessation as the only long-term solution.
Pediatricians, emergency medicine providers, parents of cannabis-using teens
Haloperidol 0.05 mg/kg recommended for acute treatment
What the researchers found
Current best evidence recommends IV rehydration and electrolyte correction, followed by haloperidol 0.05 mg/kg with or without a benzodiazepine for acute pediatric CHS. The only effective long-term treatment remains complete cessation of cannabinoid use.
Why it matters
CHS prevalence in adolescents continues to grow as cannabis becomes more accessible and potent. Clinicians need practical guidance because high-quality treatment evidence specific to pediatric populations is lacking.
The numbers in context
Haloperidol dose: 0.05 mg/kg IV; presenting features: cyclical nausea, emesis, abdominal pain, hot shower relief
How the study worked
Narrative review of current literature on adolescent CHS, covering diagnosis, pathophysiology, and treatment evidence.
What this study cannot tell us
High-quality treatment evidence for adolescent CHS remains lacking. Recommendations are based on limited data extrapolated partly from adult studies.
How to read the evidence
Narrative review providing practical guidance, but based on limited pediatric-specific evidence.
When this study was published
Published in 2022
The bigger picture
As adolescent cannabis use patterns evolve toward higher-potency products and more frequent use, CHS is likely to become an increasingly common pediatric emergency presentation.
Questions still open
- Are there pharmacological treatments that could prevent CHS relapse in adolescents who cannot achieve cessation? Does the potency of cannabis products influence CHS severity in young people?
Common questions
How is cannabinoid hyperemesis syndrome treated in adolescents?
How do you diagnose CHS in teenagers?
