Cyclophosphamid

About cyclophosphamide

Cyclophosphamide is used to treat a variety of different Krebserkrankungen. It is also occasionally used to treat severe symptoms of some connective tissue diseases (such as rheumatoide Arthritis) although these are not cancers.

In cancer, certain cells in the body grow and multiply too fast. Chemotherapy medicines like cyclophosphamide work by preventing cells from multiplying. This reduces the number of cancer cells made. Cyclophosphamide is often given alongside other medicines to help treat cancer.

Cyclophosphamide is also an immunosuppressant, which means that it suppresses your body's immune or defence system. Because of this, it is sometimes used to treat severe symptoms of conditions such as rheumatoid arthritis. The rest of this document is about cyclophosphamide when it is prescribed for cancer, so if you have been given it for a condition like rheumatoid arthritis, please speak with your doctor if you have any questions.

Before taking cyclophosphamide

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking cyclophosphamide it is important that your doctor knows:

• Wenn Sie schwanger sind oder stillen.

• Wenn Sie Probleme mit der Funktion Ihrer Nieren oder Ihrer Leber haben.

• Wenn Sie eine Infektion haben oder sich unwohl fühlen.

• If you have noticed any blood in your urine.

• Wenn Sie Diabetes (Diabetes mellitus) haben.

• Wenn Sie eine seltene erbliche Bluterkrankung namens Porphyrie haben.

• Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

• Wenn Sie andere Medikamente einnehmen. Dazu gehören alle Medikamente, die Sie ohne Rezept kaufen können, sowie pflanzliche und ergänzende Arzneimittel.

How to take cyclophosphamide

• Before you start the treatment, read any printed information you have been given by your doctor and the printed manufacturer's leaflet from inside the pack of tablets. These will give you more information about cyclophosphamide and will provide you with a full list of the side-effects which you may experience from taking it.

• Cyclophosphamide will be prescribed for you by a specialist doctor who is experienced in treating your condition. Your doctor will calculate what dose is right for you and will tell you how to take it - it is important that you take the tablets exactly as your doctor tells you to. It is usual to take one dose of tablets a day. Your dose will be printed on the label of the pack to remind you about what the doctor said to you but if you are unsure about what to do, or if you have any other concerns, you should contact your doctor or hospital clinic for advice.

• Swallow the tablet whole, with a full glassful of water. Do not break, crush or chew the tablets before you swallow.

• Cyclophosphamide tablets are best taken early in the day about an hour before a meal. However, if your stomach feels queasy after taking the tablets, you may be better taking your doses after eating some food, as this can help prevent feelings of sickness.

• While you are on cyclophosphamide, it is important that you drink plenty of fluid and that you pass urine frequently. Drinking lots of water and other fluids will help prevent a serious type of cystitis sometimes caused by this medicine.

• If you are sick (vomiting) shortly after taking a dose, or if you forget to take a dose at the correct time, contact your doctor or clinic for advice on what to do. You will be told whether to take another dose straightaway, or to just take your next dose when it is due.

Das Beste aus Ihrer Behandlung herausholen

• You must try to keep your regular appointments with your doctor or hospital. This is so your doctor can check on your progress. You will need to have regular blood tests and check-ups during your treatment with cyclophosphamide.

• It is important that you do not get pregnant or father a child while you are taking cyclophosphamide and for three months after stopping the treatment. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. If you would like to have children in the future, you should ask your doctor for advice about family planning before you begin taking cyclophosphamide. This is particularly important if you are a man, as there is a risk of reduced male fertility or sterility with cyclophosphamide treatment.

• This medicine lowers your natural protection against infection. It is important to protect yourself from serious illness by having any vaccinations your doctor offers you. If you live with other people they can also help protect you by having their own vaccinations.

• Some vaccines may not be suitable for people with lowered immune systems. Always let the person vaccinating know that you are taking this medicine.

Can cyclophosphamide cause problems?

Medicines used to treat cancer can have a number of side-effects, some of which can be delayed for several days or weeks after taking the medicine. Most chemotherapy medicines can lower the number of white cells in your blood, which increases the risk of you getting an infection. While you are taking cyclophosphamide you should take precautions to reduce the risk of getting an infection - you can do this by avoiding being with people who you know have an infection. If you think you are getting a sore throat or if you have a high temperature, please let your doctor know as soon as possible so that you can get some treatment straightaway.

Your doctor will discuss with you the possibility of unwanted side-effects from your treatment with cyclophosphamide, although not everyone experiences these. The table below contains some of the side-effects associated with cyclophosphamide. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Please let your doctor know if you experience any of the following:

If you experience any other symptoms which you think may be due to cyclophosphamide, please speak with your doctor or pharmacist for further advice.
