- Diabetes (product contains sugar) 1

Side Effects and Safety Concerns
When to Stop Use
Special Populations
- Pregnancy/breastfeeding: Consult healthcare professional before use 1
- Overdose: Seek immediate medical attention or contact Poison Control 1
Important Clinical Caveats
The mechanism of action relates to the carbohydrate-phosphoric acid formulation, which empirically decreases gastric emptying rate, providing antinauseant effects 2. However, clinicians should be aware that:
- This is intended for normally healthy persons only 1
- The product is marketed for nausea "due to overindulgence in food and drink" 1
- It contains no acetaminophen, aspirin, or caffeine 1
- It is non-drowsy 1
Maximum Daily Limit Warning
Do not exceed 24 tablets in 24 hours - this limit is critical and should not be exceeded without physician direction 1
The evidence base for Emetrol specifically is limited to FDA labeling and one older pharmacokinetic study 2. The product should not be confused with sodium phosphate solutions used for bowel preparation, which carry significant risks of electrolyte disturbances and are contraindicated in young children 3, 4, 5.
