    • trouble breathing or talking
    • unusual hoarseness
    • swelling of the mouth, face, lips, tongue or throat
  • Cyclophosphamide may increase risk of developing certain kinds of infections due to reduced white blood cells (a key component of the body's immune system that helps to fight infections). Tell your doctor immediately if you experience any symptoms of infection such as temperature exceeding 38°C, chills, cough, painful or bloody urination, feeling very tired or weak.
  • Drink plenty of water to prevent irritation of the bladder or cystitis.
  • Although rare, Cyclophosphamide may increase the risk of developing certain kinds of cancers, such as bladder cancer. The risk is higher with long term use and higher cumulative doses of Cyclophosphamide. Your doctor will perform periodic screening to manage the risk.

You should not plan to have children while taking Cyclophosphamide and for a while after treatment. If you are planning to have a child, discuss it with your doctor before you begin the treatment
  • Cyclophosphamide passes into human breast milk and may cause serious unwanted effects to the child. You should not breastfeed if you are taking Cyclophosphamide.
  • Cyclophosphamide may interact with other medicine or supplement that you are taking. Inform the doctor, pharmacist or specialty nurse (such as dermatology, gastroenterology or rheumatology) before starting on a new medicine or supplement.
