скорее всего это не аллергия, а амоксициллин-ассоциированаая сыпь
разница в том, что при следующем приеме амоксициллина эта сыпь, скорее всего, не повторится
антибиотик нужно полностью отменить или заменить на цефалоспориновую группу (решает очный врач)
лечение как при аллергии - антигистаминные при зуде и гипоаллергенная диета. сыпь пройдет за 1-2 недели

Nonallergic rash[edit]
Between 3 and 10% of children taking amoxicillin (or ampicillin) show a late-developing (>72 hours after beginning medication and having never taken penicillin-like medication previously) rash, which is sometimes referred to as the "amoxicillin rash". The rash can also occur in adults.
The rash is described as maculopapular or morbilliform (measles-like; therefore, in medical literature, it is called "amoxicillin-induced morbilliform rash".[20]) It starts on the trunk and can spread from there. This rash is unlikely to be a true allergic reaction, and is not a contraindication for future amoxicillin usage, nor should the current regimen necessarily be stopped. However, this common amoxicillin rash and a dangerous allergic reaction cannot easily be distinguished by inexperienced persons, so a healthcare professional is often required to distinguish between the two.[21][22]
A nonallergic amoxicillin rash may also be an indicator of infectious mononucleosis. Some studies indicate about 80-90% of patients with acute Epstein Barr virus infection treated with amoxicillin or ampicillin develop such a rash.[23]
