How Zyvox is given
It is recommended that treatment with Zyvox begin in a hospital.
Zyvox will be given to you or your child by the doctor or nurse.
Zyvox is a liquid which is given by slow injection into the blood (known as an intravenous infusion or "drip").
If you or your child is on dialysis, Zyvox infusion should be given after dialysis.
You or your child may be changed from Zyvox injection to an oral preparation of Zyvox (such as tablets or oral suspension) to complete your course of treatment.
How much is given
The recommended dose for adults and adolescents 12 years and older is 600mg twice daily (every 12 hours).
The recommended doses for babies and children up to 12 years of age is 10mg/kg three times daily (every 8 hours).
These doses are given intravenously by a "drip" over a period of 30 to 120 minutes.
Treatment is usually given every day for 10 to 14 days, but may given for up to 28 days.
Ask the doctor if you want more information about the dose of Zyvox and how it is given.
In case of overdose
Overdose is unlikely as treatment will be given by the doctor or nurse. The possible effects of overdose are vomiting, tremors, unsteadiness or lack of coordination.
Tell the doctor or nurse immediately if you or your child have any of these effects or if you or your child feel worse during or after treatment with Zyvox.
While being treated with Zyvox
Things you must do
Follow all instructions given by the doctor.
In some cases, additional blood tests may be required.
As part of the treatment, you or your child may be given other medicines including other antibiotics. It is important to keep taking these medicines as well as Zyvox unless you are told otherwise by your doctor or pharmacist.
It is important to tell the doctor if you develop diarrhoea during or after treatment with Zyvox. Do this even if it occurs several weeks after Zyvox has been stopped.
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 or your child may need urgent medical care.
If you or your child get a sore white mouth or tongue during or soon after treatment with Zyvox tell your doctor.
Tell the doctor if you or your child get vaginal itching or discharge.
This may mean you or your child have a fungal infection called thrush. Sometimes the use of Zyvox allows fungi to grow which causes the symptoms described above. Zyvox does not work against fungi.
Things you must not do
Do not start taking any other medicines, prescription or not, without first telling your doctor or pharmacist.
Do not give your child any other medicines, prescription or purchased from a health food shop, pharmacy or supermarket 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 or your child 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 Zyvox may react with a substance which is naturally present in these foods.
If you or your child develop a throbbing headache after eating, tell your doctor or health care professional.
Side effects
Tell the doctor or pharmacist as soon as possible if you or you child do not feel well while you are taking Zyvox.
This medicine helps most people, but it may have unwanted side effects in a few people. All medicines can have side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.
Do not be alarmed by the following lists of side effects.
You or your child may not experience any of them.
Ask the doctor or pharmacist to answer any questions you may have.
While taking it

headache
sore, white mouth or tongue (oral thrush)
vaginal itching or discharge (vaginal thrush)
pain, cramping or bloating of the abdomen
nausea or vomiting
metallic taste

Tell your doctor immediately and before you or your child are given the next dose of Zyvox if you notice any of the following:
skin reactions (hives, rash or itching)
visual disturbances or numbness or weakness of the arms and legs (rare side effects that have been primarily reported in patients treated for longer than 28 days)
tiredness, headaches, being short of breath when exercising, dizziness, looking pale, fever and chills, sore throat or bruising (these symptoms may indicate a decrease in the level of your blood cells)
sweating, feeling drunk and dizzy, muscle twitching, fever and shivering, confusion
These may be symptoms of the serotonin syndrome, which is a rare but serious side effect.
If any of the following happen, tell your or your child's doctor immediately or go to Accident and Emergency at your nearest hospital:
seizure
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, severe itching or hives or blisters on the skin.
These may be signs of a serious allergic reaction or side effect. You or your child may need urgent medical attention or hospitalisation. These side effects are rare.
After finishing it
Tell your or your child's doctor or pharmacist if you notice any of the following side effects, particularly if they occur several weeks after stopping treatment with Zyvox:
severe stomach cramps
watery and severe diarrhoea (which may be bloody), fever, in combination with one or both of the above.
Zyvox can cause some bacteria, which are normally present in the bowel and normally harmless, to multiply and therefore cause the above symptoms. You may need urgent medical attention.
Tell your or your child's doctor if you notice any other side effects.
Other side effects not listed above may also occur in some people.

Storage
Zyvox will normally be stored in a hospital. It should be stored below 25°C and should be protected from light (kept in the box and foil wrapping before use).
