INSTRUCTIONS

Take this medicine only as directed by your doctor. Do not take more or less of it, and do not take it more often than your doctor ordered. The exact amount of medicine you need has been carefully worked out. Taking too much may increase the chance of side effects, while taking too little may not improve your condition.

Cyclophosphamide 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 using cyclophosphamide, 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. Cyclophosphamide 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.

Usually it is best to take cyclophosphamide first thing in the morning, to reduce the risk of bladder problems. However, your doctor may want you to take it with food in smaller doses over the day, to lessen stomach upset or help the medicine work better. Follow your doctor's instructions carefully about when to take cyclophosphamide.

Cyclophosphamide often causes nausea, vomiting, and loss of appetite. However, it is very important that you continue to use the medicine even if you begin to feel ill. Do not stop taking this medicine without first checking with your doctor. Ask your health care professional for ways to lessen these effects.

If you vomit shortly after taking a dose of cyclophosphamide, check with your doctor. You will be told whether to take the dose again or to wait until the next scheduled dose.

If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Call your doctor or pharmacist for instructions.

The exact amount of medicine you need has been carefully worked out. Taking too much may increase the chance of side effects, while taking too little may not improve your condition.

While you are being treated with cyclophosphamide, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Cyclophosphamide 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 recently taken oral polio vaccine within the last 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.

Before having any kind of surgery, including dental surgery, or emergency treatment, make sure the medical doctor or dentist in charge knows that you are taking this medicine, especially if you have taken it within the last 10 days.

Cyclophosphamide 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, especially when your blood count is low, to reduce the risk of infection or bleeding:
If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in 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.

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by this medicine.
