Managing Nausea from Vancomycin

First-Line Treatment Options

• The National Comprehensive Cancer Network recommends dopamine receptor antagonists, such as metoclopramide (10-20 mg PO/IV every 6 hours) or prochlorperazine (5-10 mg PO/IV every 6 hours), as first-line treatment for nausea from vancomycin 1, 2

Second-Line Treatment Options

• The National Comprehensive Cancer Network suggests adding a 5-HT3 receptor antagonist, such as ondansetron (4-8 mg PO/IV every 8-12 hours), if nausea persists despite first-line treatment 1, 4, 5

Refractory Nausea Management

• The National Comprehensive Cancer Network recommends considering adding a corticosteroid, such as dexamethasone (4-8 mg PO/IV daily), for persistent nausea 4, 2
• Olanzapine (2.5-5 mg PO or sublingual every 6-8 hours) is particularly effective for refractory nausea 3

Administration Tips

• The National Comprehensive Cancer Network suggests scheduling antiemetics around-the-clock rather than as-needed for persistent nausea 1, 2
• Starting with lower doses of olanzapine (2.5 mg) in elderly or debilitated patients can minimize sedation 3

Common Pitfalls and Caveats

• Monitoring for extrapyramidal symptoms with metoclopramide, especially at higher doses, is crucial 2
• Being aware of potential sedation with antihistamines and olanzapine is important 3
• 5-HT3 antagonists can cause constipation, which may worsen overall comfort 2
• If the patient is on opioids, considering opioid rotation as persistent nausea may be opioid-induced is necessary 1, 2
