Bendamustine is a chemotherapy medicine that damages the DNA in cancer cells so they cannot grow.
What it is
Bendamustine sticks to the DNA inside cells and links the strands together. Cancer cells cannot copy themselves and die. It is often given with an antibody medicine called rituximab.
Often used for
- chronic lymphocytic leukemia (CLL)
- slow-growing B-cell non-Hodgkin lymphoma, such as follicular lymphoma
How you get it
Bendamustine is given through a vein (IV), over about 10 minutes to 1 hour depending on the brand. It is usually given on 2 days in a row, then repeated every 3 to 4 weeks. Your schedule may be different.
Common side effects and what helps
- Nausea and vomiting. Take your anti-nausea medicine as your team tells you.
- Feeling tired. Rest and short walks can help.
- Low blood counts, which raise your risk of infection and bleeding. Wash your hands often.
- Fever. Check your temperature if you feel warm or unwell.
- Rash or itchy skin. Use a gentle, unscented lotion and tell your team.
- Constipation or diarrhea. Drink fluids and tell your team if it lasts.
- Poor appetite. Try small meals.
Call your care team right away if you have
- A fever of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher, or chills
- A rash that blisters, peels, or spreads, or sores in your mouth or eyes
- Trouble breathing, swelling of the face or throat, or a racing heart
- Pain, swelling, or redness where the IV went in
- Bleeding or bruising that will not stop, black or bloody stools, or blood in your urine
