Cyclophosphamide

Cyclophosphamide is a drug commonly used in veterinary medicine to treat cancer and certain immune-mediated diseases. It is important to understand the use, dosage and possible side effects of this medication to ensure your dog's health.

Basic information on cyclophosphamide

Cyclophosphamide belongs to the class of chemotherapy drugs known as alkylating agents. It is used to fight fast-growing cancer cells by damaging the cells' DNA, which prevents them from dividing and growing.

Fields of application

  • Cancer treatment: Used for various types of cancer such as lymphoma and leukemia.
  • Immune-mediated diseases: Treatment of conditions such as systemic lupus erythematosus and rheumatoid arthritis.

Dosage and administration

The dosage of cyclophosphamide must be carefully determined by a veterinarian based on the type of disease, the dog's weight and its general health.

Important considerations

  • Individualized dosing: Each dog responds differently to cyclophosphamide, so regular blood tests are required for monitoring.
  • Route of administration: Cyclophosphamide is available in both tablet form and as an injectable solution.

Side effects

As with all chemotherapeutic agents, treatment with cyclophosphamide can cause side effects that need to be monitored and managed.

Common side effects

  • Myelosuppression: A reduction in the production of blood cells, which can lead to anemia and increased susceptibility to infection.
  • Cystitis: Frequent and painful urinary tract problems, also known as sterile hemorrhagic cystitis.

Management of side effects

  • Regular blood tests: Monitor blood cell counts and adjust dose as needed.
  • Adequate hydration: Ensure the dog is drinking plenty of fluids to minimize the risk of cystitis.
  • Symptomatic treatment: Administer medication to support the bladder and relieve pain as needed.

Long-term monitoring

Long-term use of cyclophosphamide requires careful monitoring through regular veterinary visits to check your dog's health and adjust the medication accordingly.

Important monitoring measures

  • Regular veterinary visits: At least every three to four weeks during the active treatment phase.
  • Monitoring kidney and liver function: These organs can be affected by long-term use of cyclophosphamide.

Cyclophosphamide is an effective drug for treating cancer and certain immune-mediated diseases in dogs. However, it is important that you work closely with your veterinarian to determine the correct dosage, monitor side effects and ensure your dog's health during treatment. Regular checks and adjustments are key to ensuring that your dog benefits from this treatment while minimizing risks.
