It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.
Fludarabine can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection (e.g., pneumonia). 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, especially when your blood count is low, to reduce the risk of an infection or bleeding:
If you can, avoid people with infections. Check with your doctor right away if you think you are getting an infection or if you have fever or chills; cough or hoarseness; lower back or side pain; painful or difficult urination; shortness of breath; or unusual bleeding or bruising.
Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in the urine or stools; or pinpoint red spots on your skin.
Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
Avoid contact sports or other situations where bruising or injury could occur.
You should not use this medicine if you are also taking pentostatin (Nipent®). Taking it together with this medicine may increase the chance of serious side effects.
This medicine may cause a serious type of reaction called tumor lysis syndrome. Your doctor may give you a medicine to help prevent this. Call your doctor right away if you have a decrease or change in urine amount; joint pain, stiffness, or swelling; lower back, side, or stomach pain; a rapid weight gain; swelling of the feet or lower legs; or unusual tiredness or weakness.
Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. You should not become pregnant while you are taking 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.
