What is Bendamustine for?

Bendamustine belongs to a class of medications called alkylating agents. It stops cells from replicating and dividing by interfering with their nucleic acid function. This kills cells and inhibits the growth of malignant tumours. Bendamustine is therefore used to treat multiple types of white blood cell cancers and lymph cancers, including chronic lymphocytic leukaemia, multiple myeloma and non-Hodgkin’s lymphoma.

How to use it?

This process requires many hours, and you will need to rest in the hospital ward or clinic when you are on the medicine drip. Before you start using Bendamustine, you may be given fluid drips to make you pass more urine. This may continue for another day after the treatment. You may also be given other medicines beforehand to prevent or lessen the side effects of Bendamustine. The dosage of Bendamustine is calculated by your doctor based on your total body surface area. Your doctor will advise you on the dosage and frequency depending on your condition.
