Ifosfamide belongs to the group of medicines called alkylating agents. It is used to treat cancer of the testicles as well as some other kinds of cancer. Another medicine, called mesna, is usually given along with ifosfamide to prevent bladder problems that can be caused by ifosfamide.
Ifosfamide interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by ifosfamide, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may not occur until months or years after the medicine is used.
Before you begin treatment with ifosfamide, you and your doctor should talk about the good ifosfamide will do as well as the risks of using it.
Ifosfamide is to be administered only by or under the immediate supervision of your doctor.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, ifosfamide is used in certain patients with the following medical conditions:
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For ifosfamide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to ifosfamide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Although there is no specific information comparing use of ifosfamide in children with use in other age groups, ifosfamide is not expected to cause different side effects or problems in children than it does in adults.

Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of ifosfamide in the elderly with use in other age groups.

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur.

The presence of other medical problems may affect the use of ifosfamide. Make sure you tell your doctor if you have any other medical problems, especially:
Ifosfamide is sometimes given together with certain other medicines. If you are using a combination of medicines, make sure that you take each one at the proper time and do not mix them. Ask your health care professional to help you plan a way to remember to take your medicines at the right times.
While you are receiving ifosfamide, it is important that you drink extra fluids so that you will pass more urine. Also, empty your bladder frequently, including at least once during the night. This will help prevent kidney and bladder problems and keep your kidneys working well. Ifosfamide passes from the body in the urine. If too much of it appears in the urine or if the urine stays in the bladder too long, it can cause dangerous irritation. Follow your doctor's instructions carefully about how much fluid to drink every day. Some patients may have to drink up to 7 to 12 cups (3 quarts) of fluid a day.
Ifosfamide often causes nausea and vomiting. However, it is very important that you continue to receive the medicine even if you begin to feel ill. Ask your health care professional for ways to lessen these effects.
The dose of ifosfamide will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of ifosfamide. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
It is very important that your doctor check your progress at regular visits to make sure that ifosfamide is working properly and to check for unwanted effects.
While you are being treated with ifosfamide, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Ifosfamide may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your house should not take oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the past several months. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
Ifosfamide can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take to reduce the risk of infection or bleeding:
Along with their needed effects, medicines like ifosfamide can sometimes cause unwanted effects such as blood problems, loss of hair, and problems with the bladder. These and others are described below. Also, because of the way these medicines act on the body, there is a chance that they might cause other unwanted effects that may not occur until months or years after the medicine is used. These may include certain types of cancer, such as leukemia. Discuss these possible effects with your doctor.
Although not all of these side effects may occur, if they do occur they may need medical attention.
