Cladribine

Cladribine is an injectable prescription medicine primarily used to treat hairy cell leukaemia, a rare type of blood cancer. It works by targeting abnormal white blood cells to help restore a healthy balance of blood cells in your body. This treatment is prescribed by a specialist to manage specific, serious blood disorders.

Because this medicine is given as an infusion into a vein, it is administered in a hospital or specialised clinic. It is typically given as a continuous infusion over a set number of days as a single treatment course. Since it is injected directly into your bloodstream, food intake does not affect how well it works. Eating light, nutritious meals and resting during your treatment cycle can help your body recover.

While this medication is highly effective, it can cause side effects. Common issues include fever, fatigue, and mild nausea. However, because it temporarily lowers your body's ability to fight infections, you must contact your healthcare team immediately if you develop a sudden fever, severe shivering, or unusual bruising.

Do not receive this medicine if you have had a severe allergic reaction to it in the past. Before starting, talk to your doctor if you have kidney disease, liver damage, or an active infection. It is crucial to address these conditions beforehand to ensure the treatment can be given safely.

This medicine can interact with other treatments that suppress your immune system, increasing your risk of serious infections. It is also important to talk to your doctor if you are pregnant, planning to become pregnant, breastfeeding, or if you are an older adult, as specific precautions must be taken to ensure your safety.

Cladribine provides critical therapeutic relief by targeting the root cause of specific blood cancers. The primary benefits of this treatment include:

• Promotes Long-Term Remission: A single, short course of treatment is often highly effective at putting hairy cell leukaemia into complete remission for many years.
• Restores Normal Blood Counts: By clearing out abnormal cancer cells, your bone marrow can resume producing healthy red blood cells, platelets, and white blood cells, which relieves chronic fatigue and reduces bleeding risks.
• Reduces Daily Pill Burden: Because it is typically given as a single short-term infusion course, patients do not need to take daily anticancer medications for extended periods.

• Follow your doctor's instructions on the dosage and timing of this medication.
• Cladribine is administered by the doctor or nurse in a clinical setting.
• Do not self-administer.
