Hello
Your son is having recurrent episode of cough , cold and
fever . Usually fine dusting powder, hay , mite , mold , pollen , increase or decrease in temperature ( sudden ) , pests ( cockroaches ) are certain predisposing factors , which triggers these symptoms .
These symptoms are also precursor of
bronchial asthma ( childhood ), so avoidance help greatly.
When such type of patient visit my clinic I prescribe them to take montelukast+bambuterol (10 mg / kg body weight of each tablet ). Usually patient respond at once , no need of any antibiotics .
When complete relief ,stop the drug , if recurs start again.
Levata-m is an anti
histamine and combination of levoceterizine + montelukast ( these only act as an anti allergens ) but your son require
BRONCHODILATOR .
Septilin and immune , no doubt increases immunity but not act as curative .
For low iron level try to take some good iron preparation as an OTC product.
Hope this will help you.
