My son is taking Levolin, Budecort and Montair LC for lung infection. Will these cause side effects?

Hello doctor,

My son is 6 years old. He got lung allergy so the doctor gave Levolin 100 and Budecort inhalers and some syrup like Montair LC kid. So my son is getting free from the fever, coughs, and cold by using these medicines. After completion of these medicines course, he is repeating with the same cough, cold and fever. Where as he will not eat any foods like chocolates and other flavored items, but he eats very rarely.

On using these medicines is there any side effect in his growing future? I want to know is there any permanent solution for him without using these medicines and being healthy? And he is getting this problem when there are changes in weather and if he eats any chocolate and other foods. My son gets a fever with a high temperature of 101 and goes to 103 degrees Fahrenheit. Sometimes we used to give him Meftal 8 ml and P-250 or Calpol for every four hours when the temperature was 100. After giving these medicines he was being sweated a lot specially on his head. Why there is sweating from head? Is this sweating from head cause any problem? How long should he use these medicines? What are the foods that are good for him and can we give him dry fruits and fruits? Which are best for him?
