What has NICE said?
Azacitidine (Vidaza) is not recommended for treating acute myeloid leukaemia with more than 30% bone marrow blasts in people of 65 years or older who can't have stem cell transplants.
Azacitidine should not normally be prescribed on the NHS for the condition as described above. Your doctor should talk to you about other treatment options available to you.
If you are already taking azacitidine the condition as described above, you should be able to continue taking it until you and your doctor decide it is the right time to stop.
Leukaemia is a type of cancer that affects white blood cells.
In people with acute myeloid leukaemia, stem cells inside the bone marrow (spongy material inside the bones) make too many white blood cells that aren't fully developed and don't work properly. These are called blast cells, or bone marrow blasts.
Too many blast cells can lead to symptoms such as tiredness, unusual bleeding and frequent infections, which get worse as more blast cells are made.
Treatments for acute myeloid leukaemia include different types of drugs and cell transplants.
Azacitidine is a type of drug called a hypomethylating agent, which can help to stop cancer cells from growing.
