<s>[INST] My 3 year old is throwing up clear almost stomach acid looks like. No signs of sickness before but for 3 hours tonight out of the blue. She s ate today before the vomiting started. Now she s waking up to throw up and I got her to get some water down. What do I do? [/INST] Thanks for consulting at Healthcare Magic.Vomiting in your daughter might have been caused due to infection, reflux, or food poisoning. Give Ondansetaron or Domperidone for vomiting, ORS solution to prevent dehydration and Ranitidine for acidity.If no relief consult your doctor. </s>
