Hello Let me explain in brief about ASTHMA (childhood ) so that you will understand better . Asthma :Airways hyperresponsiveness that is secondary to inflammatory airways disease that results in RECURRENT or CHRONIC episodes of wheeze, shortness of breath , chest tightness ( congestion or bronchoconstriction ) & /or cough particularly at night or in the early morning . As you mentioned in your query that all these symptoms present in your child case . Tylneol or advil is paracetamol and only helps in fever , no role in asthma . So asthma is an allergic disease and predisposing factors are , dust , mite , pests ( cockroaches ) ,hay , fodder , fine dusting powder , pollen , molds , sudden change in temperature i.e. increase or decrease of temperature . So if possible take care about these AVOIDANCE . When ( I want to tell you this is most common illness in children so need not to worry and when your son will attain 14-15 years age , these attacks of allergy will subsides itself). When such type of cases visit my clinic I prescribe them to take monteleukast+ bambuterole ( 0.2 mg of each tablet ) once or twice in day depending on the condition of symptoms and disease . Whenever patients comes with fever I advise my patient to take levofloxacin 10 mg / body weight once in day only for 3-5 days . No need of any tests and no steroid ( except in very severe cases ). Hope this information will be helpful for you.
