Child Health




Most lesions may be treated with incision and drainage alone.

Antibiotics may be considered if fever, surrounding cellulitis or co-morbidity, e.g. diabetes, or if the lesion is in a site associated with complications, e.g. face.

If recurrent boils, e.g. more than ten boils over more than three months, do a nasal swab and if indicated by results, perform staphylococcal decolonisation with a one week course of intranasal mupirocin.(Fusidic acid is not recommended due to risk of resistance developing). The patient should be advised to shower daily using triclosan body wash, as well as hot drying, ironing or bleaching towels, sheets and underclothes for the duration of treatment. Consider other household contacts.

Common pathogens:

Staphylococcus aureus

Consider MRSA if there is a lack of response to flucloxacillin.

Antibiotic treatment:

1st choice: Flucloxacillin Dose PO 50 mg/kg/day in four divided doses up to a max. 500 mg/dose on an empty stomach., for seven to ten days

A simple guide for flucloxacillin dosage is:

  • <2 years Flucloxacillin 125mg/5ml 2.5ml qid
  • 2-5 years Flucloxacillin 125mg/5ml 5ml qid
  • >5 years Flucloxacillin 250 mg/5ml 5ml qid (using 50 mg/kg/day as a cross check).


Alternatives: Erythromycin, co-trimoxazole
