Thank you for your query.
This problem can be solved easily. Continue the antiemetic thrice daily one hour before meals.Maintain a good oral hygiene
.Give soft cold
in powergyl causes vomiting
in some children. Most probably taste the medicine and see whether it is bitter or not. Replace metrogyl with some other antibiotic. I hope taking these measures will stop the vomiting.
If the problem persists then kindly consult a child specialist.
Wishing him a speedy recovery.Have a nice day
