Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, antibiotic can be the cause for her skin rashes.
Augmentin (
amoxicillin plus clavulinic acid) can cause skin reaction in the form of itching, rashes etc.
So possibility of Augmentin induced skin rashes is high in your daughter's case.
Treatment of this is stoppage of offending drug, antihistamine oral tablet and steroid containing cream for local application.
Since all these are prescribed medicines, you need to
consult doctor for their prescription.
Regarding recurrent upper
respiratory tract infection, I advise you to get done Pulmonary
vaccination with pneumococcal and
Influenza vaccines to your daughter. This will prevent recurrent episodes.
Hope I have solved your query.
Wishing good health to your daughter. Thanks.
