Print Friendly, PDF & Email

Generic Name: Cyclophosphamide
Product Name: Cycloblastin

Indication

Cycloblastin is a drug used to treat various cancerous diseases (breast and ovarian cancers, and leukaemia) and disorders of the immune system (such as  systemic lupus erythematosus and vasculitis). Cycloblastin is also used to prevent transplant rejection in some instances. If you are unsure why Cycloblastin has been prescribed for you, contact your doctor.

Action

Cycloblastin is a type of drug known as a cytotoxic agent. It works by killing rapidly dividing cells, which make it particularly useful in the treatment of certain cancers and disorders of the immune system. Unfortunately, Cycloblastin can also target normal rapidly dividing cells in the body, which can result in unwanted side effects such as nausea and vomiting, and hair loss.

Dose advice

  • Cycloblastin is available only on prescription through your doctor.
  • Always tell your doctor you are being treated with Cycloblastin before being prescribed other medication or purchasing over the counter medicines.
  • Cycloblastin should not be used in patients with certain medical conditions – be sure to tell your doctor if you suffer from any medical conditions before being prescribed Cycloblastin.
  • Cycloblastin should not be used in patients who are pregnant (ADEC Pregnancy Category D) or breastfeeding- always tell your doctor you are pregnant or breast feeding before using Cycloblastin.
  • Cycloblastin tablets should be taken at the same time each day, and swallowed whole with a glass of water.
  • Report signs of infection or unusual bleeding to your doctor. Avoid people with infections while undergoing treatment with Cycloblastin.
  • Drink plenty of fluids and urinate frequently while undergoing treatment with Cycloblastin.
