Precautions

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. Women should not become pregnant during therapy and men should not father a child while receiving this medicine and for 6 months after stopping it. If you think you have become pregnant while using the medicine, tell your doctor right away.

While you are being treated with ifosfamide, and after you stop treatment with it, do not have any immunizations (vaccines) 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. This may also cause delay in wound healing. If this occurs, there are certain precautions you can take to reduce the risk of infection or bleeding:

This medicine may cause a brain disease called encephalopathy. Tell your doctor right away if you have the following symptoms while taking this medicine: agitation, back pain, blurred vision, coma, confusion, dizziness, drowsiness, fever, hallucinations, headache, irritability, mood or mental changes, seizures, stiff neck, or unusual tiredness or weakness.

This medicine may cause drowsiness, trouble in thinking, trouble in controlling movements, or trouble in seeing clearly. Make sure you know how you react to this medicine before you drive, use machines, or do other jobs that require you to be alert, well-coordinated, or able to think or see well.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; medicine for seizures or barbiturates; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your medical doctor or dentist before taking any of the above while you are using this medicine.

This medicine may cause children to grow more slowly than usual. Talk to your child's doctor if you have any concerns.

Using this medicine may increase your risk of getting lymphoma (cancer of the lymph nodes) and other types of cancers (such as leukemia, sarcoma, thyroid cancer). Talk to your doctor if you have concerns about this risk.

If you plan to have children, talk with your doctor before using this medicine. Some men and women using this medicine have become infertile (unable to have children).

This medicine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Do not eat grapefruit or drink grapefruit juice while you are using this medicine without asking your doctor first.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (e.g., St. John's wort) or vitamin supplements.
