Bendamustine injection is used to treat chronic lymphocytic leukemia (CLL; a type of cancer of the white blood cells). Bendamustine injection is also used to treat a type of non-Hodgkins lymphoma (NHL: cancer that begins in a type of white blood cell that normally fights infection) that is slow spreading, but has continued to worsen during or after treatment with another medication. Bendamustine is in a class of medications called alkylating agents. It works by killing existing cancer cells and limiting the growth of new cancer cells.
Bendamustine comes as a powder to be added to fluid and injected intravenously (into a vein) over 30 minutes by a doctor or nurse in a medical office or hospital outpatient clinic. When bendamustine injection is used to treat CLL, it is usually injected once a day for 2 days, followed by 26 days when the medication is not given. This treatment period is called a cycle, and the cycle may be repeated every 28 days for as long as 6 cycles. When bendamustine injection is used to treat NHL, it is usually injected once a day for 2 days, followed by 19 days when the medication is not given. This treatment cycle may be repeated every 21 days for up to 8 cycles.
