Pharmacokinetics in children
The clearance of cefotaxime in neonates increases noticeably during the first days after birth. It has also been shown that the elimination half-life in neonates is longer than in older children and/or adults as a result of the renal clearance not being fully developed [Kearns 1995]. The dosage for neonates on ECMO does not have to be adjusted despite the greater volume of distribution [Ahsman 2010]. The following pharmacokinetic parameters have been found [Ahsman 2010; Aujard 1989; Kearns 1995]:

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
Dose adjustment is not required
GFR 10-30 ml/min/1.73 m2
Dose adjustment is not required
GFR < 10 ml/min/1.73 m2
The first amount given is 100% of the normal dose each time, thereafter 50% of the normal dose each time and the interval between two administrations remains as normal
Patients on dialysis
No generalized recommendations are given.

Side effects in children
Thrombophlebitis, fever, nausea, vomiting, diarrhoea, abnormal blood counts, temporarily elevated liver enzymes. Local reactions after administration, rash, abdominal pain and headaches [Jakobs 1992]. Administering it too rapidly (in less than 1 minute) via a central venous catheter can result in severe arrhythmia. Rare: pseudomembranous colitis.
The complete list of all contra-indications can be found in the national Summary of Product Characteristics (SmPC) – click here
Contra-indications in children
Cefotaxime should not be mixed with lidocaine (for intramuscular administration) in children aged less than 1 year [SmPC Claforan].

Warnings & precautions in children
Cephalosporins can in general be given to patients who are hypersensitive to penicillin, although cross-reactions have been reported. Special care is indicated in patients who previously had anaphylactic responses to penicillins.
For the treatment of sepsis in the case of Gram-negative bacteria, a combination with another suitable antibiotic such as an aminoglycoside can be considered. When treating infections in the abdominal cavity, be aware that cefotaxime does not give anaerobic coverage.
Pseudomembranous colitis may occur during antibiotic use. If pseudomembranous colitis develops, the cefotaxime treatment should be discontinued and an appropriate therapy started.
In long-term use (longer than 10 days), checks of the blood counts and hepatic and renal function are desirable.
