Hello, I can understand your concern. Children of this age group are more prone to the attacks of asthma if a familial history is present or whenever they are exposed to an allergen. The respule duolin contains salbutamol and ipratropium bromide which help in bronchodilation. This is the mainstay for the treatment of asthma along with a steroid respule if necessary. You can order a nebuliser online or get one from a pharmacy store near you. This is easily available in most of the stores. You can definitely use duolin respule whenever required(if you find the symptoms like breathlessness and wheezing in your child) Inform your doctor prior to starting so that other drugs if prescribed can be adjusted if this is used daily. Avoid exposure of child to cold, dust or pets. Hope i have answered your queries. Feel free to ask further queries. Thanks for choosing HCM
