Hi Thank you for asking HCM. I have gone through your query. Domstal (domperidone) if you had given according to the weight of kid then no problem. Don t give that in excess dosage also. Nutrolin b is for diarrhea and dysbacteriosis. But it doesn t harm your child. Carmicide also in limited intake doesn t cause any problems. Give your kid enough fluids and electrolytes. ORS is better for this. If vomiting is persisting then your kid may need injection form of anti emetic and intravenous fluid administration. In such case approach your pediatrician. Hope this may help you. Let me know if anything not clear. Thanks.
