My 22month old son had few sips of lassi from outside shop on 1st jan night. Since 2nd jan morning he is vomiting everything . Including water and breast milk. White or colourless Vomit. Gave Domstal 3ml (suggested earlier to use when needed by our family pediatrician) but he vomited that too. As vomiting got severe consulted a pediatrician in a hospital . They gave him Emeset 2mg and dose was 5ml. We waited for an hour and gave ORS after that . Only breast milk he had after that. Then after 10HOURS he vomited again completely. Doctor has asked to give Emeset 2mg syrup 3ml twice a day for 3days . To add : Since 3months old , he is a constipated baby . He passes hard poop every 3-5days. I would like to ask is Domstal safe for the baby or Emeset is fine to go with. He is 22months old and 11.1kg. Could you please clarify . Thanking in advance.
