Hi,
I guess there is no history of fall from a height in the last 24 hours (if yes, we need to take him to the ER). Repeated vomiting alone is caused usually by
acute gastritis or gastro-enteritis (in later condition, there will be loose stools also). Has he taken any drugs (especially
analgesic or
antipyretic) recently or any change from usual diet? These are the usual precipitating factors for gastritis.
If no history of fall from height, fever or loose stools, for such cases I used to give acid suppressants like pantoprazol and antiemetics like ondnsetron for 3-5 days. You can try giving
ondansetron suspension 5ml twice daily for 2 days and report to your doctor if not relieved or any above mentioned features are present.
Meanwhile give frequent sips of ORS solution or salted rice water to avoid
dehydration and give small frequent feeds. Avoid spicy and oily food for 1 week.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Muhammed Aslam TK, Pediatrician
