Hello. Thank you for asking at HCM. I feel your son is having an allergic respiratory disorder most probably allergic rhinitis with multi-trigger wheeze. I would suggest your son regular montelukast and levocetirizin which will help him reducing both rhinitis and wheezing episodes. If this does not prevent his wheezing episodes, I would suggest adding regular inhaled corticosteroids using Metered Dose Inhaler with Spacer device with face mask. However, this depends on how frequent and how severe his previous episodes have been. I would suggest you to consult an Allergist who will advise allergy testing for him and may suggest what to avoid for reducing wheezing episodes. As a general rule, I would suggest him to avoid dusts, smoke and air pollutants. Hope this will be helpful to you. Wish your son the best of the health. Regards.
