What is the most important information I should know about cyclophosphamide (Cytoxan)?
You should not use cyclophosphamide if you are allergic to it, or if you have severe bone marrow suppression.
Before you receive cyclophosphamide, tell your doctor if you have an active or recent infection, a weak immune system, heart disease, liver or kidney disease, or if you have ever been treated with radiation. Tell your doctor about all other cancer medications and treatments you are receiving.
Cyclophosphamide can lower blood cells that help your body fight infections and help your blood to clot. Your blood may need to be tested often. Avoid being near people who are sick or have infections. Avoid activities that may increase your risk of bleeding injury. Tell your doctor at once if you develop signs of infection.
Drink plenty of liquids while you are using cyclophosphamide, to prevent harmful effects on your bladder.
