1. What cefotaxime for injection is and what it is used for

Cefotaxime belongs to a group of medicines called cephalosporins which are antibiotics. These medicines work by killing bacteria that cause infections.

Cefotaxime for injection is used for the treatment of a range of serious bacterial infections including infections of the blood stream (septicaemia), bones (osteomyelitis), the heart valves (endocartitis), the membranes covering the brain (meningitis) and the lining of the abdomen (peritonitis), and to prevent and treat infections following surgical operations.

2. What you need to know before you are given cefotaxime for injection
Cefotaxime for injection should not be given if:
  • You are allergic to cefotaxime or any other cephalosporin
  • You have previously had a severe allergic reaction to penicillin or any other beta-lactam antibiotic
  • You have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking cefotaxime or other cephalosporins.

If any of the above applies to you, you should not be given Cefotaxime for Injection.

Take special care with cefotaxime for injection if:
  • you have previously had an allergic reaction to penicillin or other antibiotics of this type. Not all people who are allergic to penicillins are also allergic to cephalosporins. Before you are given this medicine your doctor should check whether you have previously had an allergic reaction to such drugs
  • you have kidney problems. You will be carefully monitored throughout your treatment
  • you are on a low salt diet, your doctor should make sure you are not receiving too much salt by way of cefotaxime injections
  • you are being treated for longer than 10 days, your doctor should monitor your blood with blood counts
  • you are going to have a blood transfusion, make sure that the doctor who organises your transfusion knows that you are having cefotaxime for injection
  • you are diabetic, you may get false positive results with urine glucose tests, such as Clinitest
  • you are taking aminoglycosides such as streptomycin and gentamicin. Your kidney function will be carefully monitored.

Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP) have been reported in association with cefotaxime treatment. Stop using cefotaxime and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.

You should be kept under observation in case you develop another infection, particularly colitis (infection of the lower bowel), while you are being treated with cefotaxime for injection.

Other medicines and cefotaxime

Taking other medicines when cefotaxime for injection is being administered can affect how it or the other medicine works. Make sure that your doctor knows what other medicines you are taking.

This includes medicines you may have bought yourself without a prescription.

Please check with your doctor if you are taking any of the following (or any other medication):
