WHY is this medicine prescribed?
Chlorambucil is used treat a certain type of chronic lymphocytic leukemia (CLL; a type of cancer of the white blood cells). Chlorambucil is also used to treat non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (types of cancer that begin in certain white blood cells that normally fight infection). Chlorambucil is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in your body.
HOW should this medicine be used?
Chlorambucil comes as a tablet to take by mouth. It is usually taken once a day for 3 to 6 weeks, but sometimes may be taken intermittently, as a single dose once every 2 weeks, or as a single dose once a month. The length of treatment depends on the types of drugs you are taking, how well your body responds to them, and the type of cancer you have. Take chlorambucil at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take chlorambucil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may adjust your dose of chlorambucil depending on your response to treatment and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment. Do not stop taking chlorambucil without talking to your doctor.
