Parents & Patients



Cefotaxime is an antibiotic that is administered intravenously. This means that it has to be given via a”drip” or “cannula”. In the UK, cefotaxime is used in children who have a serious infection or suspected infection. It is described as a third generation cephalosporin and has a broad range of activity against different bacteria. Because it is given intravenously, this antibiotic is only usually given in a hospital setting.

In children over 1 month of age it is usually given every 6 to 8 hours. The exact timing will be determined by your paediatrician. In babies under 1 month of age the dose and frequency of administration will vary depending on the exact age and weight of the baby.

Cefotaxime or a related antibiotic (ceftriaxone) are usually used if meningitis is suspected.This is when there is an infection of the central nervous system. Different combinations of antibiotics may be used particularly in babies under 1 month of age and also if the blood tests suggest a different antibiotic combination may be better for the child.
