Talk to your doctor before taking Fludara oral.
Take special care with Fludara oral:
- if your bone marrow is not working properly or if you have a poorly functioning or depressed immune system or a history of serious infections.
- Your doctor may decide to not give you this medicine, or may take precautions.
- if you feel very unwell, notice any unusual bruising, more bleeding than usual after injury, or if you seem to be catching a lot of infections.
- if during treatment you have a red to brownish urine, or have a rash or any blisters on your skin.
- Tell your doctor immediately.
These may be signs of a reduction in the number of your blood cells, which may be caused either by the disease itself or the treatment. It can last for up to a year, independent of whether or not you had treatment with Fludara oral before. During treatment with Fludara oral also your immune system may attack different parts of your body, or your red blood cells (called ‘autoimmune disorders’). These conditions can be life-threatening.
If this occurs your doctor will stop your treatment and you may receive further medication such as transfusion of irradiated blood (see below) and adrenocorticoids.
You will have regular blood tests during treatment and you will be closely monitored while you are being treated with Fludara oral.
- if you notice any unusual symptoms of your nervous system such as disturbed vision, headache, confusion, seizures.
If Fludara oral is used for a long time, its effects on the central nervous system are not known. However, patients treated with the recommended dose for up to 26 courses of treatment were able to tolerate it.
When Fludara is used at the recommended dose, following the treatment with some other medications or at the same time as some other medications, the following adverse events have been reported:
neurological disorders manifested by headache, feeling sick (nausea) and vomiting, seizures, visual disturbances including vision loss, changes in mental status (thinking abnormal, confusion, altered consciousness) and occasionally neuromuscular disorders manifested by muscle weakness in your limbs (including irreversible partial or complete paralysis) (symptoms of leukoencephalopathy, acute toxic leukoencephalopathy or posterior reversible leukoencephalopathy syndrome (RPLS)).
In patients on doses four times greater than recommended blindness, coma and death have been reported. Some of these symptoms appeared delayed around 60 days or more after treatment had been stopped. In some patients receiving Fludara doses higher than the recommended dose, leukoencephalopathy (LE), acute toxic leukoencephalopathy (ATL) or posterior reversible leukoencephalopathy syndrome (RPLS) have also been reported. Same symptoms of LE, ATL or RPLS as above described could occur. LE, ATL, and RPLS may be irreversible, life-threatening, or fatal.
Whenever LE, ATL or RPLS is suspected, your treatment will Fludara will be stopped for further investigations. If the diagnosis of LE, ATL, or RPLS is confirmed, you doctor will permanently discontinue your treatment with Fludara.
- if you notice any pain in your side, blood in your urine or reduced amount of urine.
When your disease is very severe, your body may not be able to clear all the waste products from the cells destroyed by Fludara oral. This is called tumour lysis syndrome and can cause kidney failure and heart problems from the first week of treatment. Your doctor will be aware of this and may give you other medicines to help prevent it. He/she may decide that you should start your treatment in hospital.
- if you need to have stem cells collected and you are being treated with Fludara oral (or have been).
- if you need a blood transfusion and you are being treated with Fludara oral (or have been).
In case you need a blood transfusion your doctor will ensure that you only receive blood that has been treated by irradiation. There have been severe complications and even death, from transfusions of non-irradiated blood.
- if you notice any changes to your skin either while you are receiving this medicine or after you have finished the treatment.
- if you have or have had skin cancer it may worsen or flare up again while you take Fludara oral or afterwards. You may develop skin cancer during or after Fludara oral treatment.
Pregnancy
Females: you must not become pregnant during treatment with Fludara oral because animal studies and very limited experience in humans have shown a possible risk of abnormalities in the unborn baby as well as early pregnancy loss or premature delivery. If pregnancy occurs during your treatment, you must immediately inform your doctor. Your doctor will decide with you whether you should carry on taking Fludara.
Breast-feeding:
You must not breast-feed while you are treated with Fludara.
Fertility in males and females
Females: you must use an effective method of contraception during and for 6 months after end of treatment, because Fludara oral may be harmful for the unborn baby.
Males: You are advised not to father a child and must use an effective method of contraception during and at least for 3 months after end of treatment. You should seek advice on conservation of sperm prior to treatment because Fludara oral may alter male fertility.
Both men and women who are planning to have a child after treatment are advised to talk to a doctor before start of Fludara treatment.
