Thank you for your query.
I can understand your concern. Allergic rhinitis
can be troublesome and can cause the frequent problems that you have described. However, I would refrain from giving an antibiotic every time she develops cough and fever
as most of them can be viral in origin where there is no role of an antibiotic. Bovine colostrum
may help but discuss with your doctor and put her on anti-allergic medicines for a long duration to control her allergy
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
