  • Bacterial infections of the chest (respiratory tract)
  • Complicated infections of the kidneys and upper urinary tract
  • Severe infections of the skin and soft tissue

  • Intra-abdominal infections such as peritonitis (inflammation of the peritoneum, the thin membrane that lines the abdominal wall and covers the organs within)
  • Acute bacterial meningitis
  • Infection of the blood (septicaemia)

Furthermore cefotaxime is used to treat the Lyme disease (borreliosis, an infection primarily caused by tick bites, e.g. relapsing fever).

Cefotaxime can also be used before and during surgery in order to prevent possible infections

2. What you need to know before you are given Cefotaxime

  • you have ever had a severe allergic reaction (hypersensitivity) to any other type of beta-lactam antibiotic (penicillins, monobactams and carbapenems).

Warnings and precautions

Talk to your doctor, pharmacist or nurse before you are given Cefotaxime:

  • if you have allergic reactions. If you have had any allergic reaction to other antibiotics such as penicillin, you may also be allergic to Cefotaxime. If an allergic reaction occurs, tratment must be stopped.
  • if you suffer from severe, persistent diarrhoea during or after treatment with Cefotaxime. In this case contact your doctor immediately. Do not take any anti-diarrhoea medicine without consulting your doctor.
  • if you have a widespread rash with blisters and peeling skin. (These may be signs of Stevens-Johnson syndrome or toxic epidermal necrolysis).
  • if you have kidney problems
  • if you experince e.g. impairment of consciousness, abnormal movements and cramps after being given this medicine.
  • if you are on a low salt diet. Then the sodium content of this product must be taken into account.
  • 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.

If any of these apply to you, your doctor may want to change your treatment or give you special advice.

If you are given this medicine over a longer period, your doctor will take additional care and check your blood for possible changes. Also the overgrowth of bacteria that are unsusceptible to cefotaxime must be examined regularly in this case.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. This is extremely important, as using more than one medicine at the same time can strengthen or weaken the effect of the medicines.

Cefotaxime may interfere with:

  • diuretics (used to increase the flow of urine)
  • probenecid
  • aminoglycoside antibiotics (such as gentamycin and streptomycin used to treat infections), other antibiotics (such as tetracycline, erythromycin and chloramphenicol)

In some cases your doctor will arrange further monitoring, but this is routine and nothing to worry about.

It is important to tell the doctor that you are taking this medicine if you require any blood, urine or diagnostic tests.

The effect of the contraceptive pill may be decreased during therapy with Cefotaxime. Additional non-hormonal contraceptive precautions should therefore be taken during therapy with Cefotaxime.

Pregnancy and breast-feeding

Before starting treatment, you must tell your doctor if you are pregnant or if you intend to become pregnant. Your doctor will then decide whether you should receive Cefotaxime

Mothers who wish to breast-feed should discuss this with their doctor who will then advise you on what to do.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

Cefotaxime should not affect your ability to drive or operate machinery.

You may start to move abnormally, suffer from sudden involuntary muscle contractions, dizziness or feel less alert.

If this happens, do not drive or use any tools or machines.

3. How to use Cefotaxime

This medicine will always be administered by a doctor or nurse because it needs to be given either as an injection or by a drip.

Adults and adolescents over 12 years

You usually receive 2 to 6 g cefotaxime daily. The daily dose should be divided in two single doses every 12 hours. The dosage may be varied according to the severity of your infection and your condition.

  • Common infections in presence (or suspicion) of sensitive bacteria: 1g every 12 hours (i.e. total daily dose of 2g)
  • Infections in presence (or suspicion) of several sensitive or moderately sensitive bacteria: 1-2 g every 12 hours(i.e. total daily dose of 2-4g)
  • Severe infections or for injections that cannot be localised: 2-3 g as a single dose every 6 to 8 hours (i.e. a maximum daily dose of 12g).

Newborns (0-28 days), infants and children up to 12 years of age

The dosage is dependent on the severity of the infection.

The usual dosage for newborns, infants and children is 50 to 100 to 150 mg cefotaxime per kg body weight per day, divided into 2 to 4 single doses (i.e. every 12 to 6 hours).

For very severe or life-threatening infections up to 200 mg cefotaxime per kg body weight per day, divided into 2 to 4 single doses, may be required. The doctor will take the differences in maturation of the kidneys and their function into account, especially in newborns from 0-7 days.

Premature infants

The recommended dosage is 50mg per kg body weight per day divided into 2 to 4 doses (every 12 to 6 hours). This maximum dose should not be exceeded due to the not yet fully matured kidneys.

Elderly

Provided that your kidney and liver function is normal, no dosage adjustment is required.

People with kidney and/or liver problems

If you have problems with your kidneys and/or liver, you may be given a lower dose. You may need to have blood tests to check that you are getting the dose you need. Your doctor will decide on the dose.

Other special recommendations

Gonorrhoea

You will receive a single injection of 500 mg – 1 g Cefotaxime as an injection into a muscle or a vein for treatment of gonorrhoea.

Bacterial meningitis

Adults receive a daily dose of 9 to 12 g cefotaxime divided into equal doses every 6 to 8 hours.

Children receive 150 to 200 mg per kg body weight divided into equal doses every 6 to 8 hours.

Newborns 0-7 days old babies receive 50 mg per kg body weight every 12 hours, 7 – 28 days old infants every 8 hours.

Prevention of infections (perioperative prophylaxis)

You may be given between 1 g and 2 g cefotaxime before an operation for the prevention of possible infections. If the operation lasts longer than 90 minutes, you may be given an additional dose preventively.

Infections inside the abdomen

You should be given a combination of cefotaxime and an antibiotic acting against ‘anaerobic’ bacteria.

Tratment duration

Your treatment duration depends on the severity of your infection as well as on your recovery from your illness.

You will usually continue to be given the medicine for at least 2 to 3 days after you have started to recover from your illness. Treatment over at least 10 days is necessary in infections caused by the bacterium Streptococcus pyogenes.

If you use more Cefotaxime than you should:

It is most unlikely that you will be given too much medicine by the nurse or doctor. Your doctor and nurse will be monitoring your progress, and checking the medicine that you are given. Always ask if you are not sure why you are getting a dose of medicine.

If you forget to use Cefotaxime:

Your doctor or nurse have instructions when to give you your medicine. It is most unlikely that you will not be given the medicine as it has been prescribed. If you think that you may have missed a dose then talk to your nurse or doctor. It is important that the course of treatment your doctor has prescribed is taken. You may start to feel better but it is important not to stop taking this medicine, until the doctor advises, otherwise your condition may get worse again.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

If you stop using Cefotaxime:

Low dosage, irregular administration or stopping treatment too early can compromise the outcome of the treatment or lead to a relapse, whose treatment is more difficult. Please follow the instructions of your doctor.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
