Cyclophosphamide
Cyclophosphamide is an alkylating medicine used in specialist treatment for certain cancers and severe immune-mediated diseases. It can affect healthy rapidly dividing cells as well as the target disease, so monitoring is essential.
Key points
- Cyclophosphamide may be part of regimens for Malignant Lymphoma, Leukaemia, Multiple Myeloma or selected autoimmune disease.
- Blood counts, kidney and liver function, urine or bladder symptoms and infection risk require review during treatment.
- Fever, painful or bloody urination, unusual bleeding or severe breathlessness needs urgent clinical contact.
Listings are for comparison and general information, not an oncology or immunosuppression regimen; suitability and supply depend on specialist, clinician and pharmacy checks, monitoring and prescription requirements.
How cyclophosphamide works
After activation in the liver, cyclophosphamide forms compounds that damage DNA and reduce cell replication. This can suppress malignant cells or an overactive immune response, but it also explains effects on bone marrow, fertility and other tissues.
Clinically meaningful forms
Tablets and injectable formulations are used in different protocols and are not interchangeable without specialist direction. Hydration and bladder-protection measures depend on the regimen.
Important safety checks
Specialists review blood counts, infection, kidney and liver function, pregnancy and fertility goals. Vaccination and other immunosuppressive medicines require coordination. Cyclophosphamide can irritate the bladder and can have delayed risks, so follow-up continues beyond a single administration.
When to seek urgent care
Contact the treating team urgently for fever, chills, sore throat, new cough, unusual bruising or bleeding, blood in urine, painful urination, markedly reduced urine, chest pain or severe breathlessness. Pregnancy during treatment needs immediate specialist advice.
