First-Line Non-Sedating Options

5-HT3 Receptor Antagonists are the most effective non-sedating antiemetics with high-quality evidence supporting their use, according to the National Comprehensive Cancer Network 1
Ondansetron is available as oral tablets, oral dissolving tablets (ODT), oral soluble film, or IV formulations at 8 mg per dose, and provides effective relief, as reported in the Journal of Clinical Oncology 2
Granisetron provides an excellent antiemetic effect (RR 0.45 compared to placebo for vomiting prevention), as reported in the Journal of Clinical Oncology 2
Palonosetron is a longer-acting 5-HT3 antagonist with approximately 100-fold higher binding affinity for the 5-HT3 receptor, and is particularly effective for delayed nausea and vomiting, according to the National Comprehensive Cancer Network 1

Metoclopramide is a dopamine receptor antagonist that is less sedating than other dopamine antagonists, but requires monitoring for extrapyramidal symptoms, as reported in the World Journal of Emergency Surgery 3
Prochlorperazine is a dopamine receptor antagonist that is somewhat less sedating than promethazine, but still has potential for akathisia, as reported in the World Journal of Emergency Surgery 3 and Praxis Medical Insights 4

Combining medications with different mechanisms of action, such as ondansetron + dexamethasone, is more effective than single agents for patients with persistent nausea, as reported in the Journal of Clinical Oncology 2 and Praxis Medical Insights 4
