Modification and duration of therapy for staphylococcal scalded skin syndrome in children

In children being treated with intravenous therapy for staphylococcal scalded skin syndrome, switch to oral therapy when:

  • the clinical features have improved
  • the primary source of infection is controlled
  • oral intake is tolerated.

Oral antibiotic choice should be based on antibiotic susceptibility testing, with dosing and duration of therapy based on the underlying infection. In children with staphylococcal scalded skin syndrome associated with a skin and soft tissue infection, the total duration of therapy (intravenous + oral) is typically 10 days. A suitable oral regimen might include:

1cefalexin 12.5 mg/kg up to 500 mg orally, 6-hourly cefalexin

OR

1flucloxacillin 12.5 mg/kg up to 500 mg orally, 6-hourly. flucloxacillin

In children with staphylococcal scalded skin syndrome, if adherence to a 6-hourly regimen is unlikely, a suitable oral regimen might be:

cefalexin 20 mg/kg up to 750 mg, orally 8-hourly1. cefalexin

Cefalexin is often preferred to flucloxacillin in children, because the liquid formulation is better tolerated.

For children with penicillin hypersensitivity who tolerated initial intravenous therapy with cefazolin, cefalexin (at the dosages above) may be appropriate. Cefalexin can also be used for children with nonsevere (immediate or delayed) hypersensitivity to penicillins or children with severe immediate2 hypersensitivity to a penicillin other than amoxicillin or ampicillin.

For children at increased risk of MRSA infection, or who have severe immediate2 hypersensitivity reaction to amoxicillin or ampicillin or severe delayed3 hypersensitivity to any penicillin, use:

1trimethoprim+sulfamethoxazole 4+20 mg/kg up to 160+800 mg orally, 12-hourly trimethoprim + sulfamethoxazole

OR

2clindamycin 10 mg/kg up to 450 mg orally, 8-hourly4. clindamycin

1 Unpublished pharmacokinetic and pharmacodynamic modelling data for cefalexin show similar levels of target attainment with the 6- and 8-hourly regimens above. It is the consensus view of the Antibiotic Expert Group that either regimen can be used.Return
2 Severe immediate hypersensitivity reactions include anaphylaxis, compromised airway, airway angioedema, hypotension and collapse.Return
3 Severe delayed hypersensitivity reactions include cutaneous adverse drug reactions (eg drug rash with eosinophilia and systemic symptoms [DRESS], Stevens–Johnson syndrome/toxic epidermal necrolysis [SJS/TEN], severe blistering or desquamative rash), and significant internal organ involvement (eg acute interstitial nephritis).Return
