Thanks for writing to health care magic.
If she is diagnosed of eye allergy antibiotics should not be given to her.
Does she have any other allergy like allergic rhinitis
and recurrent cold) or skin allergy
or bronchial asthma
In a case of eye allergy antibiotics may not be useful. You are mentioning that symptoms improved with antibiotics. May be you failed to notice that the drops that were given are not antibiotics.
