Hello, thanks for using HCM.
is a bacterial infection with group A Streptococcus
. It presents with fever, characteristic rash, swollen tonsils, painful throat etc and it has the potential of spreading and becoming a generalized infection (sepsis
is a third generation cephalosporine antibiotic which is a broad spectrum antibiotic and Group A Strep is sensitive to it and not much of antibiotic resistance
has been reported with Strep. Generally, antibiotic response to common infections requires 2 to 3 days before visible clinical changes can occur such as decrease in temperature, patient becoming more active, increase appetite etc.
In your son's case, its been four days since he started his antibiotic yet he is still having a fever which makes us to think that probably there is a problem with the antibiotic or there is another cause of the fever. Probable causes related to the antibiotic could be resistance, under dosage and and in very rare cases a side effect of the antibiotic. I will suggest you re-visit your doctor for re-evaluation and tests including throat swap for culture and sensitivity.
