Hi Doctor, My son is 3.5 years old. A month back one night, he suffered a bad asthma attack (with 60 breaths per minute) and we had go rush him to ER here in Chennai. We being first time parents didnt realise that a cough and cold could be so serious until he started having really heavy breaths. So far we had taken only body temperature increase, seriously. We still feel ashamed and sorry for taking him to the ER at the last minute. We dont want him to suffer like that again for sure. He was on nebs and ok within 24 hours and discharged within 48 hours. The docs mentioned that this could maybe be an allergy to something. He is an active child, we cannot cut him off from totally off from few triggers like dust, pollen etc as he daily plays for atleast 1 hour outside. But we have cut off all cold products from his diet. My question is again he has got chest congestion 45 days after the first time, but breathing so far is only 20 breaths per minute. His coughs sound heavy with phelgm in his chest. I know that this is the time to act. The docs told to use saline water for treating blocked nose. However to use levolin kit for low respiratory congestion. My big question is I have been avoiding the usage of levolin kit unnecessarily (or rather I naively I feel it is best this way). When the congestion becomes heavy, which is evident by the way he coughs, I have now started using this low respiratory medication. When best should I use this spray. Should I start when he starts coughing itself. Heavy Chest congestion seems to occur to him after few days (3 to 4 days) of what seems like dry cough. During this time we do give him saline solution to clear his blocked nose. Kindly advice when to start using lower respiratory medication. Thanks a lot. Regards, Shyam Jebadev Moses Worried Father
