Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seem that she has got a severe
allergic reaction leading to hives and stomach pain, vomiting ad
diarrhea can be due to allergic reaction while can also be due to side effect of the medicines that are given to her in loads..
I would suggest you to immediately take her to Emergency room or an Allergist and get her evaluated along with allergic tests like RAST test,
Patch test, food challenge test etc to rule out the exact cause of allergic reaction and treatment can be planned accordingly..
She will also be advised to take anti emetics like
Domperidone to relieve vomiting, anti diarrhea medicines like
Furazolidone and also fluid replacement orally as well as intravenous drips..
Tylenol will be advised for fever..
Hope this information helps..
Thanks and regards.
