What Cubicin is used for

What it is used for

Cubicin is an antibiotic used in adults to treat:

  • complicated infections of the skin and the tissues under the skin
  • blood infections or infections of the tissues that line the inside of the heart (including heart valves) that are caused by Staphylococcus aureus bacteria.

Cubicin will not work against infections that cause pneumonia (a serious infection or inflammation in the lung tissue).

How Cubicin works

Cubicin is an antibiotic that belongs to a group of medicines called cyclic lipopeptides. These antibiotics work by killing the Gram-positive bacteria that are causing your infection.

Ask your doctor if you have any questions about why Cubicin has been prescribed for you.

Your doctor may have prescribed it for another purpose.

This medicine is available only with a doctor's prescription.

Cubicin is not addictive.

Before you have Cubicin

When you must not have it

You must not have Cubicin if you are allergic (hypersensitive) to daptomycin, the active ingredient, or to any of the other ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

You must not have this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.

In that case, it should be returned to your pharmacist.

Before you are given it

This medicine is not to be given to a child under the age of 18 years.

There is not enough information to recommend the use of this medicine for children under the age of 18 years.

Tell your doctor if you:

  • are allergic to any other medicines, foods, dyes or preservatives
  • have or have had any kidney problems. Your doctor may need to change the dose of Cubicin
  • are suffering from diarrhoea
  • are pregnant, or intend to become pregnant
Like most medicines, Cubicin is not recommended in pregnancy. Your doctor will discuss with you the risks and benefits of having Cubicin during pregnancy.
  • are breastfeeding or plan to breastfeed.
You should not breast-feed your child during your treatment with Cubicin.

Taking other medicines

Tell your doctor if you are taking, or have recently taken, any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines and Cubicin may interfere with each other.

Tell your doctor if you are taking:

  • Warfarin (a medicine used to prevent blood clots).
  • Statins or fibrates (medicines used to lower cholesterol)
  • Cyclosporin (a medicine used to help prevent organ transplant rejection or to treat certain problems with the immune system)
  • Non-steroidal anti-inflammatory drugs (NSAIDs) or COX-2 inhibitors, e.g. celecoxib (medicines used to relieve pain, swelling or other symptoms of inflammation)
  • Tobramycin, another antibiotic used to treat various types of bacterial infections.

These medicines may be affected by Cubicin, or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor and pharmacist have more information.

If you have not told your doctor about any of these things, tell him/her before you are given this medicine.

How Cubicin is given

Your medicine 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.

How much is given

Your doctor will decide what dose and how long you will receive Cubicin. The dose will depend on how much you weigh and the type of infection being treated. The usual adult dose is 4 mg/kg daily for skin infections and 6mg/kg daily for blood or heart infections.

If you are over 65 years of age, you will be given the same dose as other adults, provided your kidneys are working well.

How it is given

Cubicin is given directly into your blood stream by intravenous injection over about 2 minutes or by infusion (drip) over about 30 minutes.

When it is given

Your doctor will determine when you are given Cubicin.

How long it is given for

A course of treatment usually lasts for 7 to 14 days for skin infections and 2 to 6 weeks for blood or heart infections. Your doctor will decide how long you should be treated.

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.

If you miss a dose

If you think that you have missed a dose of treatment, tell a doctor or nurse or pharmacist at once.

Since Cubicin is given by a doctor or nurse, once a day, it is very unlikely that you will miss a dose.

If you are given too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26) or go to Accident and Emergency at your nearest hospital, if you think that you may have been given too much Cubicin. Do this even if there are no signs of discomfort or poisoning.

Since Cubicin is given by a doctor or nurse, once a day, it is very unlikely that you will be given too much of the medicine. Your doctor, nurse or pharmacist will be monitoring your progress and checking the medicine that you are given.

While you are being given Cubicin

Things you must do

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

If you develop itching with swelling or skin rash or difficulty breathing while you are being given Cubicin contact your doctor immediately.

Tell your doctor immediately if you develop any of the following symptoms:

Tender or aching muscles or muscle weakness.
Your doctor will make sure that you have a blood test and will decide whether or not you should continue Cubicin treatment. The symptoms generally go away within a few days of stopping Cubicin.
Any unusual tingling or numbness of the hands or feet, loss of feeling or difficulties in moving.
Your doctor will decide whether or not you should continue treatment.
Diarrhoea, especially if you notice blood.
Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.
New or worsening fever, cough or difficulty breathing.
These may be the signs of a rare, but serious lung disorder called eosinophilic pneumonia. If you experience these symptoms, tell your doctor. Your doctor will check the condition of your lungs and will decide whether or not you should continue Cubicin treatment.

Your doctor will perform blood tests to monitor the health of your muscles both before you start treatment , and frequently during the course of treatment with Cubicin.

Your doctor will monitor your kidney function and the health of your muscles more frequently during Cubicin treatment if you have kidney problems.

If you get a sore white mouth or tongue while you are being given Cubicin or soon after stopping it, tell your doctor. Also tell your doctor if you get vaginal itching or discharge.

This may mean you have a fungal infection called thrush. Sometimes the use of Cubicin allows fungi to grow and the above symptoms to occur. Cubicin does not work against fungi.

You should tell your doctor that you are being treated with Cubicin if you are about to have a blood clotting test or any other blood tests.

It may interfere with the results of some tests.

If you become pregnant while taking this medicine, tell your doctor immediately.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking Cubicin.

It may affect other medicines used during surgery.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Cubicin.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking Cubicin.

Things you must not do

Do not stop receiving Cubicin because you are feeling better, unless advised by your doctor.

If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or it may return.

Do not give this medicine to anyone else, even if their condition seems similar to yours.

Do not use it to treat any other complaints unless your doctor tells you to.

Things to be careful of

Be careful driving or operating machinery until you know how Cubicin affects you.

Cubicin generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, Cubicin may cause dizziness or tiredness in some people.

Side effects

Tell your doctor or nurse as soon as possible if you do not feel well while you are taking Cubicin.

Cubicin helps most people with infections, but it may have unwanted side-effects in a few people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

After you are given Cubicin

Each Cubicin vial is to be used for one injection or infusion only. Any unused portion remaining in the vial should be discarded.

Diarrhoea is a common problem that happens when taking antibiotics. It usually stops when the antibiotic is stopped.

Other medicines of the same class as Cubicin may also cause diarrhoea.

Do not take any diarrhoea medicine without first checking with your doctor.
