Hi, thanks for the query. H.C.M.
Two rounds of antibiotics within a short period, this is the cause of concern.
Small children are prone to many allergens and same thing happened to your son.
Please note down, is there wheezing
, whistling sound, difficulty (mild) in breathing?
If above things have your child than there is no need of any antibiotics because child has allergic symptoms.
Simple bronchodilators are recommended in this type of cases but please use these drugs after consultation with a doctor.
Take few precautions as mite, dust, fine powder, pollen,smoke, sprays are responsible for allergy
Get in blood examination for eosinophils count and deal accordingly.
Regards. Dr. HET
