hi,
welcome to this forum.
Can understand your concerns.
Repeated episodes of vomiting for 5 days along with fever can occur in food poisoning, acute gastroentritis, upset stomach.
In food poisoning, there is simultaneous appearance of fever and vomiting. After sometime, the child may develop loose stools.
In acute
gastroenteritis both loose tools and vomiting are present. Fever usually accompanies both of them.
In my opinion, your child needs antibiotic like
ofloxacin for a period of 3 days. Child should also be given antiemetic drug like
ondansetron.
However, since these are prescription medicines, and dosage depends on weight of child. Therefore, a visit to a doctor should be done for starting antibiotics.
Child should be given adequate
liquid diet, so that the
dehydration does not occur.
I hope this will help you.
Wishing your child good health. Take care.
