J What Linezolid is and what it is used for
Linezolid is an antibiotic of the oxazolidinones group that works by stopping the growth of certain bacteria (germs) that cause infections. It is used to treat pneumonia and some infections in the skin or under the skin. Your doctor will have decided if Linezolid is suitable to treat your infection.
What you need to know before you are treated with Linezolid
You should not be treated with Linezolid:
• If you are allergic to linezolid or any of the other ingredients of this medicine (listed in section 6).
• If you are taking or have taken within the last 2 weeks any medicines known as monoamine oxidase inhibitors (MAOIs for example phenelzine, isocarboxazid, selegiline, moclobemide). These medications may be used to treat depression or Parkinson's disease.
• If you are breast-feeding. This is because it passes into breast milk and could affect the baby.
Linezolid may not be suitable for you if you answer yes to any of the following questions. In this case tell your doctor as he/she will need to check your general health and your blood pressure before and during your treatment or may decide that another treatment is better for you.
Ask your doctor if you are not sure whether these categories apply to you:
• Do you have high blood pressure, whether or not you are taking medicines for this?
• Have you been diagnosed with an overactive thyroid?
• Do you have a tumour of the adrenal glands (phaeochromocytoma) or carcinoid syndrome (caused by tumours of the hormone system with symptoms of diarrhoea, flushing of the skin, wheezing)?
• Do you suffer from manic depression, schizoaffective disorder, mental confusion or other mental problems?
• Are you taking any of the following medicines?
- decongestant, cold or flu remedies containing pseudoephedrine or phenylpropanolamine
- medicines used to treat asthma such as salbutamol, terbutaline, fenoterol
- antidepressants known as tricyclics or SSRIs (selective serotonin reuptake inhibitors) for example amitriptyline, cipramil, clomipramine, dosulepin, doxepin, fluoxetine, fluvoxamine, imipramine, lofepramine, paroxetine, sertraline
- medicines used to treat migraine such as sumatriptan and zolmitriptan
- medicines used to treat sudden, severe allergic reactions such as adrenaline (epinephrine)
- medicines which increase your blood pressure, such as noradrenaline (norepinephrine), dopamine and dobutamine
- medicines used to treat moderate to severe pain, such as pethidine
- medicines used to treat anxiety disorders, such as buspirone
- an antibiotic called rifampicin.

Linezolid 2mg/ml Solution for Infusion
For further information, consult the Summary of Product Characteristics (SmPC).
Dosage and Method of Administration
Linezolid should only be initiated in a hospital environment and after consultation with a relevant specialist such as a microbiologist or an infectious diseases specialist.
Patients who commence treatment on the parenteral formulation may be switched to either oral presentation when clinically indicated. In such circumstances, no dose adjustment is required as linezolid has an oral bioavailability of approximately 100%.
The solution for infusion should be administered over a period of 30 to 120 minutes.
The recommended linezolid dosage should be administered IV or orally twice daily.
Recommended dosage and duration for adults:
The duration of treatment is dependent on the pathogen, the site of infection and its severity, and on the patient's clinical response.
The following recommendations for duration of therapy reflect those used in the clinical trials. Shorter treatment regimens may be suitable for some types of infection but have not been evaluated in clinical trials.
The maximum treatment duration is 28 days. The safety and effectiveness of linezolid have not yet been established for treatment periods longer than 28 days.
• are anaemic (have low red blood cells)
• are prone to getting infections
• have a history of seizures
• have liver problems or kidney problems particularly if you have dialysis
• have diarrhoea.
Tell your doctor immediately if during treatment you suffer from:
• Problems with your vision such as blurred vision, changes in colour vision, difficulty in seeing detail or if your field of vision becomes restricted.
• Loss of sensitivity in your arms or legs or a sensation of tingling or pricking in your arms or legs.
• You may develop diarrhoea while taking or after taking antibiotics, including linezolid. If this becomes severe or persistent or you notice that your stool contains blood or mucus, you should stop being given Linezolid immediately and consult your doctor. In this situation, you should not take medicines that stop or slow bowel movement.
• Recurrent nausea or vomiting, abdominal pain or rapid breathing.
Other medicines and Linezolid
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines including medicines obtained without a prescription.
There is a risk that linezolid may sometimes interact with certain other medicines to cause side effects such as changes in blood pressure, temperature or heart rate.
Tell your doctor if you are taking or have taken within the last 2 weeks the following medicines as you must not be given Linezolid if you are already taking these medicines or have taken them recently. (See also Section 2 "You should not be treated with Linezolid").
• Monoamine oxidase inhibitors (MAOIs for example phenelzine, isocarboxazid, selegiline, moclobemide). These may be used to treat depression or Parkinson's disease.
Also tell your doctor if you are taking the following medicines. Your doctor may still decide to give you Linezolid, but will need to check your general health and your blood pressure before and during your treatment. In other cases, your doctor may decide that another treatment is better for you.
• Decongestant cold or flu remedies containing pseudoephedrine or phenylpropanolamine.
• Some medicines used to treat asthma such as salbutamol, terbutaline, fenoterol.
• Certain antidepressants known as tricyclics or SSRIs (selective serotonin reuptake inhibitors). There are many of these, including amitriptyline, cipramil, clomipramine, dosulepin, doxepin, fluoxetine, fluvoxamine, imipramine, lofepramine, paroxetine, sertraline.
• Medicines used to treat migraine such as sumatriptan and zolmitriptan.
• Medicines used to treat sudden, severe allergic reactions such as adrenaline (epinephrine).
• Medicines which increase your blood pressure, such as noradrenaline (norepinephrine), dopamine and dobutamine.
• Medicines used to treat moderate to severe pain, such as pethidine.
• Medicines used to treat anxiety disorders, such as buspirone.
• Medicines that stop blood clotting, such as warfarin.
Linezolid with food and drink
• Avoid eating large amounts of mature cheese, yeast extracts, or soya bean extracts, for example soy sauce and drinking alcohol, especially draught beers and wine. This is because this medicine may react with a substance called tyramine which is naturally present in some foods. This interaction may cause an increase in your blood pressure.
• If you develop a throbbing headache after eating or drinking, tell your doctor or pharmacist immediately.
Pregnancy, breast-feeding and fertility
The effect of linezolid in pregnant women is not known. Therefore it should not be used in pregnancy unless advised by your doctor. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
You should not breast-feed when being given Linezolid because it passes into breast milk and could affect the baby.
Driving and using machines
Linezolid may make you feel dizzy or experience problems with your vision. If this happens, do not drive or operate any machinery. Remember that if you are unwell your ability to drive or operate machinery may be affected.
Linezolid contains glucose monohydrate and sodium
Each 1ml of Linezolid solution contains 45.7mg glucose monohydrate (13.7g glucose in one bag).
Tell your doctor or nurse if you are diabetic.
Continued over page
No increase in the recommended dosage or duration of treatment is required for infections associated with concurrent bacteraemia. The dose recommendation for
Paediatric Population: There are insufficient data on the pharmacokinetics, safety and efficacy of linezolid in children and adolescents (< 18 years old) to establish dosage recommendations. Therefore, until further data are available, use of linezolid in this age group is not recommended.
Elderly patients: No dose adjustment is required.
Patients with renal insufficiency: No dose adjustment is required.
Patients with severe renal insufficiency (i.e. CLCR < 30ml/min): No dose adjustment is required. Due to the unknown clinical significance of higher exposure (up to 10-fold) to the two primary metabolites of linezolid in patients with severe renal insufficiency, linezolid should be used with special caution in these patients and only when the anticipated benefit is considered to outweigh the theoretical risk.
Each 1ml of Linezolid solution contains 0.38mg sodium (114mg sodium in one bag).
Tell your doctor or nurse if you are on a low sodium diet.
Jl How Linezolid is given Adults
This medicine will be given to you through a drip (by infusion into a vein) by a doctor or healthcare professional. The usual dose for adults (18 years and older) is 300ml (600mg linezolid) twice daily which is given directly into the blood stream (intravenously) by a drip over a period of 30 to 120 minutes.
If you are on kidney dialysis, you should be given Linezolid after dialysis.
A course of treatment usually lasts 10 to 14 days, but can last up to 28 days. The safety and effectiveness of this medicine have not been established for treatment periods longer than 28 days. Your doctor will decide how long you should be treated.
While you are given Linezolid, your doctor should perform regular blood tests to monitor your blood count.
Your doctor should monitor your eyesight if you are given Linezolid for more than 28 days.
Use in children and adolescents
Linezolid is not normally used to treat children and adolescents (under 18 years old).
If you receive more Linezolid than you should
If you are concerned that you may have been given too much Linezolid, tell your doctor or a nurse at once.
If you miss a dose of Linezolid
As you will be given this medicine under close supervision, it is very unlikely that you will miss a dose. If you think that you have missed a dose of treatment, tell a doctor or nurse at once.

As approximately 30% of a linezolid dose is removed during 3 hours of haemodialysis, Linezolid should be given after dialysis in patients receiving such treatment. The primary metabolites of linezolid are removed to some extent by haemodialysis, but the concentrations of these metabolites are still very considerably higher following dialysis than those observed in patients with normal renal function or mild to moderate renal insufficiency. Therefore, linezolid should be used with special caution in patients with severe renal insufficiency who are undergoing dialysis, and only when the anticipated benefit is considered to outweigh the theoretical risk.
To date, there is no experience of linezolid administration to patients undergoing continuous ambulatory peritoneal dialysis (CAPD) or alternative treatments for renal failure (other than haemodialysis).
Patients with hepatic insufficiency: Patients with mild to moderate hepatic insufficiency (Child-Pugh class A or B): No dose adjustment is required.
Patients with severe hepatic insufficiency (Child-Pugh class C): As linezolid is metabolised by a nonenzymatic process, impairment of hepatic function would not be expected to significantly alter its metabolism and, therefore, no dose adjustment is recommended. However, there are no pharmacokinetic data and limited clinical experience of linezolid in patients with severe hepatic insufficiency. Linezolid should be used with special caution in patients with severe hepatic insufficiency and only when the anticipated benefit is considered to outweigh the theoretical risk.
Instructions for Use and Handling
