lJ What AmBisome is and what it is used for
What AmBisome is
AmBisome is an antifungal antibiotic. The active ingredient in AmBisome is amphotericin B.
AmBisome is given as an infusion into a vein (a drip) in hospital by a doctor or nurse.
What AmBisome is used for
AmBisome is used to treat serious infections caused by fungi:
■ Fungal infections of one or more deep organs of the body.
■ Suspected fungal infections in patients with a raised temperature and neutropenia.
Neutropenia is a reduced number of white blood cells called neutrophils. These are important in fighting infections. Neutropenia can be a side effect of cancer treatments.
Before you are given AmBisome your doctor will check that your fever is not due to bacteria or viruses. You will probably have had one or more antibiotics already. A fever which continues despite treatment may be due to a fungal infection. It's difficult to confirm this with current tests, however.
■ Visceral leishmaniasis, a disease caused by a parasite.
2.| Before you are given AmBisome
Before your first treatment
Before your first treatment your doctor may give you a small amount of AmBisome. They will then wait for approximately 30 minutes to see whether you have an allergic reaction, before continuing the infusion of the full dose.
Your doctor will not give you AmBisome
■ If you are allergic (hypersensitive) to amphotericin B or any of the other ingredients of AmBisome. However, if your condition is life-threatening you
may be given AmBisome if your doctor believes that only AmBisome can help you.
■ If you have previously experienced a severe allergic reaction (anaphylactic or anaphylactoid) to
AmBisome. Symptoms of such immediate and life-threatening allergic reactions include: flushing, itching, sickness, swelling of the face, mouth, tongue and airways, often enough to cause difficulty breathing.
Your doctor will take special care with AmBisome
■ If you have a severe allergic (anaphylactic) reaction. If this happens your doctor will stop the infusion.
■ If you get other reactions related to the infusion. If this happens, your doctor may slow down the infusion, so you receive AmBisome over a longer period of time (approximately 2 hours). Your doctor may also give you medicines to prevent or treat infusion-related reactions, such as diphenhydramine (an antihistamine), paracetamol, pethidine (for pain relief) and/or hydrocortisone (an anti-inflammatory medicine that works by reducing the response of your immune system).
■ If you are taking other medicines that may cause kidney damage, see Taking other medicines, right. AmBisome may cause damage to the kidney. Your doctor or nurse will take regular blood samples. This is to test creatinine (a chemical in the blood that reflects kidney function), and electrolyte levels (particularly potassium and magnesium)
Both of these can be abnormal if you have kidney problems. This is particularly important if you are taking other medicines that may cause damage to the kidney.
The blood samples will also be tested for changes in your liver, and your body's ability to produce new blood cells and platelets.
■ If blood tests show a change in kidney function,
or other important changes. If this happens, your doctor may give you a lower dose of AmBisome or stop treatment.
■ If blood tests show that your potassium levels are low. If this happens, your doctor may prescribe a potassium supplement for you to take while you are treated with AmBisome.
■ If you have a white blood cell transfusion.
Sudden and severe problems in the lungs can happen if you are given AmBisome infusion during or shortly after a white blood cell transfusion.
Your doctor will recommend that the infusions are separated by as long a period as possible. This will reduce the risk of lung problems, and your lungs will be monitored.
■ If you have had kidney failure and are having dialysis. Your doctor may start AmBisome treatment after the procedure has ended.
■ If you have diabetes. AmBisome contains approximately 900 mg of sucrose (sugar) in each vial. Tell your doctor if you have diabetes.
Taking other medicines
Tell your doctor if you are taking any other medicines,
or have recently taken any. This includes medicines and
herbal products you bought without a prescription.
Medicines that may cause kidney damage:
■ Medicines that suppress the immune system
(immunosuppressants), such as ciclosporin and tacrolimus.
■ Certain antibiotics called aminoglycosides (including gentamicin, neomycin and streptomycin) and polymixins.
■ Pentamidine a medicine used to treat pneumonia in people with AIDS and leishmaniasis.
^ Tell your doctor if you are taking any of these medicines. AmBisome may make any kidney damage caused by the medicine worse. If you are taking any of these medicines, your doctor or nurse will take regular blood samples to check your kidneys.
Medicines that may lower your potassium levels:
■ Corticosteroids, anti-inflammation medicines that work by reducing the response of your immune system.
■ Corticotropin (ACTH), used to control the amount of corticosteroid produced by your body. The body produces corticosteroid in response to stress.
■ Diuretics, medicines that increase the amount of urine your body produces. This includes furosemide.
■ Digitalis glycosides, medicines produced from the foxglove plant and used to treat heart failure. AmBisome may worsen the side effects of digitalis, such as heart rhythm changes.
■ Muscle relaxants usually used during surgery, such as tubocurarine. AmBisome may increase the muscle relaxant effect.
^ Tell your doctor if you are taking any of these medicines.
Other medicines:
■ Antifungal medicines, such as flucytosine. AmBisome may worsen the side effects of flucytosine. This includes changes in the body's ability to produce new blood cells. This may be seen in blood tests.
■ Certain cancer medicines, such as methotrexate, doxorubicin, carmustine and cyclophosphamide. Taking this type of medicine with AmBisome may cause kidney damage, wheezing or trouble breathing and low blood pressure.
■ White blood cell (leukocyte) transfusions.
Sudden and severe problems in the lungs can happen if you are given AmBisome infusion during or shortly after a white blood cell transfusion.
Your doctor will recommend that the infusions are separated by as long a period as possible. This will reduce the risk of lung problems and your lungs will be monitored.
^ Tell your doctor if you are taking any of these medicines.
Pregnancy and breast-feeding
Tell your doctor before you are given AmBisome if you are pregnant, planning to become pregnant, or if you are breast-feeding.
Your doctor will only prescribe AmBisome if they think the benefits of treatment outweigh the risks to you and your unborn child or your baby.
Do not drive or operate machinery
Some of the possible side effects of AmBisome could affect your ability to drive or use machines safely,
See Section 4, Possible side effects.
AmBisome contains sugar
Tell your doctor if you have diabetes. AmBisome contains approximately 900 mg of sugar (sucrose) in each vial.

Suspected fungal infections in patients with a raised temperature and neutropenia: The recommended daily dose is 3 mg per kg body weight, per day. AmBisome will be given to you until your temperature is normal for 3 days in a row. However, AmBisome must not be given for more than 42 days in a row.
Visceral leishmaniasis:
You may be given a total dose of between 21 and 30 mg per kg body weight, over a period of 10 to 21 days. Your doctor will decide on the amount of AmBisome you will receive and over how many days it will be given.

Dosage for patients with kidney problems
AmBisome has been given to patients with kidney problems at doses ranging from 1 to 5 mg per kg of body weight per day. No change in dose or frequency of infusion is required. Your doctor or nurse will take regular blood samples to test for changes in kidney function during AmBisome treatment.

How long will the infusion take?
Normally the infusion will take 30 to 60 minutes. For doses greater than 5 mg per kg of body weight per day, the infusion could take up to 2 hours.

Interference with Phosphorus blood test results.
