1. Ondansetron Use in Young Children:

   • Ondansetron can be used for vomiting but should only be given to young children under strict medical supervision.

2. Consult a Pediatrician:

   • Vomiting in a 1.5-year-old can lead to dehydration and may indicate an underlying issue. Seek medical evaluation.

3. Avoid Self-Medication:

   • Do not administer Emeset or any antiemetic without a doctor's advice. Identifying the cause of vomiting is crucial.

4. Immediate Care:

   • Keep your child hydrated with small sips of oral rehydration solution.
   • Seek prompt medical attention if vomiting persists, or if your child shows signs of lethargy or cannot keep fluids down.

Please contact your pediatrician for a proper diagnosis and treatment plan.
