my son is 3yrs old.. he regularly catches cold and cough and has WALRI every time he has cold and cough.. till he was an year and half I had to admit him in hospital everytime he has severe cough.. but after an year and half I could manage his cold at home and there was no hospitalisation needed... recently he again had a cold and cough episode again and had to give him furacort nebuliser to control his cough.. his pediatrician prescribed montair lc kid tab for 3 months.. how does this tab work and can a tablet be taken for 3 months? will the child get used to it? plz tell if I should continue the medication?
