The dose you will be given and the frequency of the dose will depend on:

• The type and severity of infection you have
• Your kidney function.

• The child’s age

If you have problems with your kidneys or require dialysis, your doctor may need to reduce your dose of this medicine

Route and method of administration

For intravenous use.

Fomicyt is given to you into a vein (a drip) by a doctor or a nurse. The infusion will normally take 15 to 60 minutes, depending on your dose. Usually this medicine is given 2, 3 or 4 times a day.

Your doctor will decide how long your treatment should last depending on how fast your condition will improve. When treating bacterial infections it is important to complete the full course of treatment. Even after the fever has passed and the symptoms have abated, treatment should be continued for a few days more.

Certain infections, such as infections of the bones, may require an even longer treatment period after the symptoms have subsided.

It is unlikely that your doctor or nurse will give you too much medicine. Ask them immediately if you think that you have been given too much of this medicine.
