Thank you for your query on Healthcare Magic,
You can continue the prescribed medication for cold and cough
Consult you Pediatrician
again and he will examine the child and her respiratory system and will advise you the need for a bronchodilator
Dont use any unprescribed medication as some times it is not going to help the child and the cough may be due to just a upper airway infection and doent require nebulization.
Hope i have answered your query.
