Vomikind Tablet - Ondansetron Dosing
Vomikind is a brand name for Ondansetron (4 mg and 8 mg tablets/ODT), a 5-HT3 serotonin receptor antagonist used as an antiemetic.
Adults
| Situation | Dose | Route |
|---|---|---|
| Nausea & vomiting (general) | 4-8 mg per dose | Oral (PO) |
| Max single dose (non-elderly) | up to 16 mg | Oral/IV |
| Elderly patients | Max 8 mg per dose, infused slowly if IV | Oral/IV |
| Post-op nausea (PONV) | 8 mg ODT | Oral |
- Frequency: typically every 8 hours as needed
- Hepatic impairment: dose reduction may be required (max 8 mg/day)
- Renal impairment: no dose adjustment needed
Children (Weight-Based)
| Weight | Dose |
|---|---|
| 8-15 kg | 2 mg |
| 15-30 kg | 4 mg |
| >30 kg | 8 mg |
- Weight-based formula: 0.15 mg/kg/dose PO
- Age: generally used in children ≥6 months
- Give oral rehydration 15-30 minutes after ondansetron in gastroenteritis
Key Safety Points
- QT prolongation risk - dose-dependent; check ECG in at-risk patients (elderly, electrolyte abnormalities)
- Correct potassium and magnesium before administration (FDA recommendation)
- Avoid in patients on other serotonergic agents (risk of serotonin toxicity)
- Promethazine (a competing antiemetic) carries an FDA boxed warning against use in children <2 years - ondansetron is the preferred choice in pediatrics
