My 6 year old son has constant coughing and wheezing with light fever. The medicines given to him are nebulization (asthalin), antibiotics for 10 days and steroid for 5 days. In all the previous occurences, he would get fine with only nebulization. I am not sure why he was given antibiotics and steroid. During his visit in the morning today, his oxygen level was 94%. Please advise.
