- used as an immunosuppressant in order to treat severe rheumatoid arthritis.
-

- In order to obtain maximum benefit, you should take cyclophosphamide on
- an empty stomach. However, if stomach upset occurs, you can take it with food
- or milk (unless your doctor directs you to do otherwise).
- The timing of the doses of this anticancer medication is important. Be
- sure you completely understand your doctor's instructions on how and when this
- medication should be taken. Try not to miss any doses.
- If you miss a dose of this medication, do not take the missed dose at
- all; just return to your regular dosing schedule. Do not double the next
- dose.

-
- Diarrhea, loss of appetite, nausea, or vomiting. These side effects may

- medication is stopped.
-

-

- tract.
- 2. Phenobarbital can increase the side effects of cyclophosphamide.

- thiazide diuretics (water pills) with cyclophosphamide can lead to bone marrow

- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to cyclophosphamide.
- * Before starting to take this medication, be sure to tell your doctor if
- you have ever had blood disorders, chronic or recurrent infections, gout,
- kidney disease, or liver disease.
- * Before having surgery or any other medical or dental treatment, tell
- your doctor or dentist you are taking this drug.
- * Cyclophosphamide tablets contain the color additive FD&C Yellow No. 5
- (tartrazine), which can cause allergic-type reactions (fainting, shortness of
- breath, rash) in certain susceptible individuals.
- * You should not receive any immunizations or vaccinations while taking
- this medication. Cyclophosphamide decreases the effectiveness of the vaccine
- and may result in an infection if a live-virus vaccine is administered.
- * It is important to drink plenty of fluids (three quarts each day) while
- taking this medication. If the drug is allowed to concentrate in the bladder,
- it can cause bloody urine and can damage the kidneys or bladder.
- * This medication can lower your platelet count, which can decrease your
- body's ability to form blood clots. You should, therefore, be especially
- careful while brushing your teeth, flossing, or using toothpicks, razors, or
- fingernail scissors. Try to avoid falls and other injuries.
- * This drug can decrease fertility in both men and women.
- * Be sure to tell your doctor if you are pregnant. Birth defects have
- been reported in both animals and humans whose mothers received
- cyclophosphamide during pregnancy. The risks should be discussed with your
- doctor. Also, tell your doctor if you are breast-feeding an infant. Since
- the drug passes into breast milk, a woman should stop breast-feeding before
- starting cyclophosphamide therapy.
- Women of childbearing potential who are not already pregnant when
- treatment with cyclophosphamide is begun need to use some sort of birth
- control to prevent pregnancy from occurring. However, oral contraceptives
- (birth control pills) may not be recommended by your doctor since they may
- interfere with this medication. Consult with your physician about alternative
- methods of birth control.
