Also tell the doctor if your diet contains a lot of mature cheese, yeast extracts, meat extracts, soya bean extracts (e.g., soy sauce), draught beers or wine. Linezolid may react with a substance which is naturally present in these foods.

How to take this medicine

It is recommended that treatment with linezolid begin in a hospital.

If you do not understand the instructions on the box, ask the doctor for help.

How much to take

The recommended dose for adults and adolescents 12 years and older is one 600mg tablet twice daily (every 12 hours).

When to take it

Take the dose as prescribed by your doctor. Linezolid can be taken before, during or after meals.

How long to take it for

Continue taking linezolid until you finish the tablets unless your doctor recommends otherwise.

A course of treatment usually lasts 10 to 14 days, but may be up to 28 days

Do not stop taking linezolid unless your doctor tells you to, even if you feel better. If you do not complete the full course prescribed by the doctor, the bacteria causing the infection may continue to grow and multiply. The infection may not clear completely or it may return.

If you forget to take it

If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time.

Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to the Emergency department at your nearest hospital if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

The possible effects of overdose are vomiting, tremors (shaking), unsteadiness or lack of coordination.

While you are taking this medicine

Things you must do

Tell your doctor immediately if you become pregnant while you are taking linezolid.

Tell all doctors, dentists and pharmacists who are treating you that you are taking linezolid.

Follow all instructions given by your doctor. In some cases, additional blood tests may be required.

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

As part of the treatment, you may be given other medicines including other antibiotics. It is important to keep taking these medicines as well as linezolid unless you are told otherwise by your doctor.

It is important to tell your doctor if you develop diarrhoea during or after treatment with linezolid. Do this even if it occurs several weeks after linezolid has been stopped.

If you get a sore white mouth or tongue while taking or soon after stopping linezolid tell the doctor.

Tell the doctor if you get vaginal itching or discharge. This may mean you have a fungal infection called thrush.

Things you must not do

Do not give this medicine to anyone else, even if they seem to have the same condition as you.

Do not take linezolid to treat any other complaint unless your doctor tells you to do so.

Do not start taking any other medicines, prescription or not, without first telling your doctor or pharmacist.

Do not take any medicine to treat diarrhoea without first checking with the doctor. Diarrhoea may be caused by a serious condition affecting the bowel. You may need urgent medical care.

Avoid eating too much mature cheese, yeast extracts, meat extracts or soya bean extracts (e.g., soy sauce). Avoid drinking alcohol, especially draught beers and wine. This is because linezolid may react with a substance which is naturally present in these foods.

If you develop a throbbing headache after eating, tell your doctor or health care professional.

Things to be careful of

Be careful driving or operating machinery, until you know how l affects you. No effects on the ability to drive or use machines have been seen with linezolid. However, linezolid may cause dizziness or tiredness in some people.
