What it is used for

Cubicin is used in adults and children (1 to 17 years of age) to treat complicated infections of the skin and the tissues under the skin.

How Cubicin works

How Cubicin is given

Cubicin will be given to you by a doctor or a nurse as it needs to be given as an injection or infusion into a vein.For adults, the dose will depend on how much you weigh and the type of infection being treated.
For children (1 to 17 years of age), the dose will depend on the age of the patient, how much the child weighs,and the type of infection being treated.
Your doctor will decide on the dose and how long you will receive Cubicin.
If you have kidney problems, you may receive Cubicin less often, e.g. every other day. If you are receiving dialysis, and your next dose of Cubicin is due on a dialysis day, you will usually be given Cubicin after the dialysis session.

How it is given

Adults: Cubicin is given directly into your blood stream by intravenous injection over about 2 minutes or by infusion (drip) over about 30 minutes.
Children ( 7-17 years of age): Cubicin is given directly into the blood stream by infusion (drip) over 30 minutes.
