Hello. Thank you for asking at HCM. The medicines that your son is currently seem appropriate to me. But most important thing I want you to know is that correct technique of using inhalers is the most important aspect of asthma management. So if your son is comfortable with inhalers (MDI), please make sure he follows every step of using MDI every time, i.e., shaking the inhaler, expiration, pressing inhaler with deep inspiration, withholding breath and rinsing and gargling. If the technique is not proper, drug will not go into the lung in sufficient amount. I would personally suggest to use spacer device with inhaler as it increases the amount of drug reaching lungs, technique is easier and it reduces amount of drug reaching in stomach, hence lesser side effects. I would also make sure that you know types of medicines. Budecort inhaler & Montair LC are controller medicines for asthma (you have to take the regularly to prevent attacks) and Asthalin inhaler is a reliever medicine (you have to use it when your son has worsening asthma symptoms/asthma attack) I would also suggest your son regular breathing exercises, Yoga & Pranayama and to have a healthy nutritious diet rich in vitamins & minerals. This will help him in a long run. He should avoid dusts, smoke & air pollution as much as possible. Well, above medicines control asthma. If the cause of asthma is allergy, I would suggest you to consult an Allergist-Immunologist who will suggest allergy testing and depending on the results may suggest your son allergen immunotherapy which changes immunesystem to reduce allergy symptoms. Hope this will help you. Wish your son the best of the health. Regards.
