Key points

  • Bendamustine is given into a vein on two days in a row and repeated every 3 or 4 weeks [1].
  • With rituximab (BR), it controlled the disease longer than R-CHOP and caused fewer side effects [2].
  • It weakens the immune system for a long time; infection prevention is needed [1].

What is this drug and how does it work?

For patients

Bendamustine damages the DNA of cancer cells so they cannot divide [1]. It is usually given with rituximab.

For physiciansSpecialist notes
For physicians

An alkylating agent with a benzimidazole ring (a structure resembling a purine analogue) [1].

Which cancers is it used for?

For patients
What is this drug for?
  • Indolent B-cell lymphomas (follicular, marginal zone) and mantle cell lymphoma, with rituximab [1, 2]
  • Chronic lymphocytic leukaemia (now largely replaced by targeted drugs) [1, 3]

How it is taken and dosing

Show detailsHide

A short infusion into a vein on two days in a row, every 28 days (in CLL and with rituximab) or every 21 days [1]. An anti-sickness medicine is given before the infusion.

Serious side effects

For patients

Serious side effects: serious infections (even months after treatment), an allergic reaction during the infusion, severe skin rashes, tumour lysis, liver damage and skin damage if the drug leaks out of the vein [1].

For physiciansSpecialist notes
For physicians
  • Myelosuppression and prolonged lymphopenia; opportunistic infections (Pneumocystis, CMV, herpes) [1].
  • Infusion reactions; severe skin reactions (especially with allopurinol) [1].
  • Tumour lysis, hepatotoxicity, second malignancies, extravasation [1].

When should I call my doctor?

  • Fever or chills
  • A widespread rash or blisters
  • Burning or swelling at the infusion site
  • Yellowing of the skin or eyes

Interactions, pregnancy and precautions

  • Other medicines: allopurinol increases the risk of a severe skin reaction [1].

Frequently asked questions

Why are preventive antibiotics given after bendamustine?

Bendamustine keeps the lymphocytes low for a long time and raises the risk of particular infections [1].
