Taking other medicines

Tell your doctor if you are taking any other medicines including any that you have bought from a pharmacy, supermarket or healthfood shop.

Talk to you doctor about the need for an additional method of contraception while using CEFTRIAXONE VIATRIS. Some antibiotics may decrease the effectiveness of some birth control pills, although this has not been shown with CEFTRIAXONE VIATRIS.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while being given CEFTRIAXONE VIATRIS.


CEFTRIAXONE VIATRIS can be given in two ways:

CEFTRIAXONE VIATRIS must only be given by a doctor or nurse.

CEFTRIAXONE VIATRIS should not be mixed or administered with calcium-containing solutions, even via different infusion lines.

Your doctor will decide what dose and how long you will receive CEFTRIAXONE VIATRIS for. This will depend on your infection and other factors, such as your weight. For most infections, CEFTRIAXONE VIATRIS is usually given once a day. The length of treatment is usually 4-14 days.

Sometimes a single dose of CEFTRIAXONE VIATRIS is required for the treatment and prevention of certain infections.

While you are using CEFTRIAXONE VIATRIS

Things you must do

If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.

If you get severe diarrhoea, tell your doctor, pharmacist or nurse immediately. Do this even if it occurs several weeks after CEFTRIAXONE VIATRIS has been stopped. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.

If you get a sore or furry white mouth or tongue while using or soon after stopping CEFTRIAXONE VIATRIS, tell your doctor. Also tell your doctor if you get vaginal itching or discharge. This may mean you have a fungal infection called thrush. Sometimes the use of CEFTRIAXONE VIATRIS allows fungi to grow and the above symptoms can occur. CEFTRIAXONE VIATRIS does not work against fungi.

If you become pregnant while you are using CEFTRIAXONE VIATRIS, tell your doctor immediately.

If you are about to start taking any new medicine, tell your doctor and pharmacist that you are using CEFTRIAXONE VIATRIS.

If you have to test your urine for sugar while you are being given CEFTRIAXONE VIATRIS, make sure your doctor knows which type of test you use. CEFTRIAXONE VIATRIS may affect the results of some of these tests.

If you have any blood tests, tell your doctor you are being given CEFTRIAXONE VIATRIS. Complete blood counts should be done at regular intervals as CEFTRIAXONE VIATRIS may affect the results of some blood tests.

Tell all the doctors, dentists and pharmacists who are treating you that you are using CEFTRIAXONE VIATRIS.

Things you must not do

Do not give CEFTRIAXONE VIATRIS to anyone else even if they seem to have the same condition as you.

Do not use CEFTRIAXONE VIATRIS to treat other complaints unless your doctor says to.

Things to be careful of

Be careful driving or operating machinery until you know how CEFTRIAXONE VIATRIS affects you. CEFTRIAXONE VIATRIS generally does not cause any problems with your ability to drive or operate machinery. However, as with many other medicines, CEFTRIAXONE VIATRIS may cause dizziness in some people.


CEFTRIAXONE VIATRIS will be stored in the pharmacy or on the ward.

The powder for injection is kept in its original container in a cool, dry place protected from light and moisture, where the temperature stays below 25°C.

The reconstituted solution should be used immediately, but if necessary, can be kept in a refrigerator between 2 °C and 8 °C for not more than 24 hours after mixing. Do not freeze.

Side effects

Tell your doctor, nurse or pharmacist as soon as possible if you do not feel well while you are receiving CEFTRIAXONE VIATRIS. As with all prescription medicines, it is possible that CEFTRIAXONE VIATRIS will cause you to experience some unwanted side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor to answer any questions you may have.

The above list includes serious side effects that may require medical attention. Serious side effects are rare.


Tell your doctor immediately if you notice any of the following side effects, even if they occur several weeks after stopping treatment with CEFTRIAXONE VIATRIS:

  • severe abdominal cramps or stomach cramps
  • watery and severe diarrhoea, which may also be bloody
  • fever, in combination with one or both of the above.

These are rare but serious side effects. You may have a serious condition affecting your bowel. You may need urgent medical attention. However, these side effects are rare.

Treatment with CEFTRIAXONE VIATRIS, particularly in elderly patients with serious kidney or nervous system problems may rarely cause consciousness, abnormal movements, agitation and convulsions.

Other side effects not listed above may also occur in some patients.

Tell your doctor if you notice anything else that is making you feel unwell.

Overdosage of the medicine

As your dose of CEFTRIAXONE VIATRIS will be determined and administered by a medical specialist, the chance of receiving an overdose is most unlikely. However, if an overdose should be given, your specialist will give the appropriate treatment.
