Cyclophosphamide is a drug used to treat a number of cancers, and it is used to treat patients with lupus when major organs, such as the kidneys, are affected. It is also used to treat severe inflammation that has not responded to corticosteroids. In lupus, the immune system is too active. Cyclophosphamide slows down the immune system so that disease activity can be reduced.

Cyclophosphamide is a very powerful drug. It can have a number of effects on the body. As a result, it is important that you understand how it is used to treat your lupus. You will need to work closely with your doctor and nurse to make sure that the amount of the drug you are taking gives you the benefits you need with as few side effects as possible.
