Cytoxan contains Cyclophosphamide.
Cyclophosphamide is a chemotherapy medicine used to treat certain cancers, such as lymphoma, leukaemia and breast cancer. It is also used for some serious autoimmune diseases, like severe lupus and vasculitis.

What is it used for?
- Some cancers, including lymphoma, leukaemia and breast cancer
- Severe autoimmune conditions such as lupus nephritis and vasculitis

How does it work?
Cyclophosphamide damages the DNA of fast-dividing cells, such as cancer cells and overactive immune cells, which stops them growing.

- QWhy do I need blood tests on Cytoxan?
- A
To check your blood cells, liver and kidneys, and sometimes the level of medicine in your blood, so any problems can be caught early.
- QCan I have vaccines while taking Cytoxan?
- A
Most non-live vaccines, like flu and COVID-19, are recommended. Live vaccines should usually be avoided. Always check with your doctor.
- QWhat should I do if I get an infection on Cytoxan?
- A
Contact your doctor straight away, even for something that seems minor, like a fever or sore throat. Infections can become serious more quickly when your immune system is lowered.
