Can We Give Cefspa To An Asthma Patient?

my sister having fever with flue since yesterday morning, my mother took her to a doctor and he has prescribed some medicines but unfortun. she was feeling tightness in chest and having problem in breathing, actually mom forgot to tell doctor that she has allergic asthma (allergic from dust etc..) as she has taken the pills few min. later she feels breathing problem as well as having pain in stomoch and in legs.
then i took her another doctor at night she nabolised her with AFROVENT and given an inj. AVIL after she felt better but still having problem in breathing and pain in legs. Doctor advised CEFSPA (antibiotic) but i am puzzled either is it good for her or not because of her asthama problem. pls help me thanks.
