my daughter is having allergy cough for past 1.5 years. the cough is severe at night and when she has viral infection.last year most of the night she will cough and vomit. I was giving budecort even then she will cough at night. only if I give any antihistamine the cough will not be there. is it safe to give antihistamine every day? what medicine is safe to give in long run will she outgrow this cough ? it's hard to see the kids suffer I am giving homeo medicine for past 6 months. is it safe to give for long run ?
