Side Effects

Cyclophosphamide is a chemotherapy drug associated with a range of side effects, which vary in severity from mild to potentially serious.

Common side effects include:

  • Nausea or vomiting
  • Hair loss
  • Diarrhea
  • Mouth sores
  • Loss of appetite
  • Increased risk of infection due to lowered white blood cells (immunosuppression)
  • Bruising, nosebleeds, or bleeding gums caused by low platelets
  • Fatigue and feeling weak or tired
  • Missing menstrual periods (amenorrhoea) in some women

These effects can be bothersome but are generally manageable or temporary[1][3][5].

Serious side effects require immediate medical attention and may include:

  • Fever or chills (indicating possible infection)
  • Cough or hoarseness
  • Painful or difficult urination, or blood in the urine (suggests bladder irritation or cystitis)
  • Shortness of breath
  • Dizziness, confusion, or agitation
  • Swelling of the feet or lower legs
  • Allergic reactions such as difficulty breathing, swelling of the face or throat, or severe rash
  • Unusual bleeding or bruising

Monitoring by healthcare professionals is essential to detect and treat these effects as early as possible[1][3][5].

Long-term and rare side effects observed with cyclophosphamide use include:

  • Bladder toxicity, including irritation and an increased risk of bladder cancer, especially with high doses or prolonged use
  • Cardiac complications, such as heart failure or irregular heartbeat
  • Lung damage (pulmonary fibrosis)
  • Liver injury, rarely leading to hepatic veno-occlusive disease
  • Permanent infertility, primarily in women (risk of irreversible amenorrhoea)
  • Development of secondary cancers (such as bladder cancer and blood cancers), particularly after years of use or at high cumulative doses
  • Persistent fatigue and muscle weakness, sometimes related to skeletal muscle dysfunction

The likelihood of these complications increases with higher doses, long-term treatment, and advanced age. Regular follow-up is important for timely detection of these risks[2][4][5][6].

Other possible side effects:

  • Skin rashes
  • Pain at the injection site (if injected)
  • Yellowing of the eyes or skin (jaundice)
  • Frequent urination or unusual thirst
  • Sores in the mouth or on the lips

These may be mild and often resolve as treatment continues, but persistent or bothersome effects should be reported to your healthcare provider[1][7].
