Nausea Management

Introduction to Haloperidol

Haloperidol is a dopamine receptor antagonist, effective for nonspecific nausea and vomiting, and is recommended by the National Comprehensive Cancer Network for these indications 1
Haloperidol has strong evidence supporting its use for nausea control, with a high recommendation from the World Journal of Emergency Surgery guidelines based on intermediate quality evidence 2

Haloperidol is useful in scenarios of persistent nausea, where it can be titrated to maximum benefit and tolerance, according to the National Comprehensive Cancer Network guidelines 1
Haloperidol is a first-line option for opioid-induced nausea, as per the National Comprehensive Cancer Network guidelines 1, 3
Haloperidol is recommended as a first-line intervention for immediate symptom relief in cannabinoid hyperemesis syndrome, a condition characterized by cannabis-induced nausea 4

Haloperidol can be administered via multiple routes, including oral and intravenous/subcutaneous, with a dosage of 0.5-2 mg every 3-6 hours 2

If haloperidol is contraindicated or ineffective, consider other dopamine receptor antagonists, 5-HT3 receptor antagonists, benzodiazepines, corticosteroids, anticholinergic agents, or antihistamines, as suggested by the National Comprehensive Cancer Network 1, 2
For persistent nausea, consider adding a second agent with a different mechanism of action, such as ondansetron, rather than replacing haloperidol 2
Consider haloperidol's dual benefit in patients with concurrent delirium and nausea, as it may provide synergistic effects 2
