Hello Madam, Welcome to Health Care Magic. I read carefully your query and I understand your concern. One in five children who take antibiotics may develop diarrhea, and in your child s case the causative might be the oral amoxicillin and clavulanate potassium. It is more common in children aged under two years and can occur with any type of antibiotic. I would suggest you not to stop the medication before you consult your child s doctor to see if the antibiotic should be changed. To avoid your child from dehydration, so your first concern should be giving him enough liquids. If your baby isn t also vomiting, continue to give him breast milk or formula. If your baby can t keep breast milk or formula down, I may suggest that you start giving him a pediatric electrolyte solution. Hope I answered to your question. Feel free to ask again. Take Care, Dr. Ina Zaimi
