Dosages

Febrile neutropenia, complicated infections of urinary tract, abdomen or skin/soft tissue; severe pneumonia (including HAP and ventilator associated pneumonia, and pulmonary infections in CF)
  • Intravenous
    • 1 month up to 18 years
      [5] [6] [7] [8] [9] [10] [11] [13] [14]

      • 320/40 mg/kg/day in 4 doses.
        Maximum for febrile neutropenia and CF: 18/2.25 g/day.
        Maximum for abdominal infections: 16/2 g/day.
        Alternative: administer as a continuous infusion: 300/37.5 mg/kg/day, maximum of 18/2.25 g/day

      • Duration of treatment:

        The length of treatment should be guided by the severity of the infection and the clinical and bacteriological process. A course of treatment of at least 5 and at most 14 days is recommended, taking into account a continuing administration during 48 hours after solving clinical signals and symptoms.

      • CF: preferably use in combination with an aminoglycoside or another antibiotic with an anti-Pseudomonas effect.
Infections (without clinical suspicion of meningitis) caused by microorganisms susceptible at increased exposure ('I')
  • Intravenous
    • 1 month up to 18 years
      [18] [19]

      • 400 / 50 mg/kg/day in 4 doses, max 4 g / 0,5 g per dose.  Extended infusion time in 3 hours.

Renal impaiment in children > 3 months

Adjustment in renal impairment as specified:

GFR 50-80 ml/min/1.73 m2
Dose adjustment is not required
GFR 30-50 ml/min/1.73 m2
100 percentage of single dose and dosing interval : 8 uur
GFR 10-30 ml/min/1.73 m2
100 percentage of single dose and dosing interval : 12 uur
GFR < 10 ml/min/1.73 m2
50 percentage of single dose and dosing interval : 8 uur
Clinical consequences

Neurotoxicity can occur (for example convulsions) at high parenteral doses.

Patients on dialysis

The manufacturer says that dialysis patients can use 50% of the normal dose each time, dosage interval 8 hours between 2 dosages. After each dialysis an extra dose of 50% of the normal dosage each time can be administered.

Warnings & precautions in children

The serum galactomannan indication (Aspergillus antigen) can give a false positive reaction. There can be crossover sensitivity with other penicillins and cephalosporin. Severe and persistent diarrhoea during or after a treatment can be signs of colitis as a result of an antibiotic. The treatment must immediately be stopped in such cases.
