Cytorox® 1000mg/10ml Injection (Cytarabine) – Chemotherapy (Rx)

Quick answer: Cytorox 1000mg (cytarabine) is a 10ml vial of chemotherapy for acute leukaemias, especially acute myeloid leukaemia (AML). Hospitals often use this larger vial when the treatment plan calls for higher doses. It is given only in hospital, usually as a drip into a vein. MedHub supplies it on prescription with delivery across Pakistan.

For patients and families

What is Cytorox 1000mg?

Cytorox 1000mg contains 1000mg of cytarabine in 10ml of solution and comes from Pharmasol in Pakistan. Leukaemia cells grow and divide much faster than most healthy cells. Cytarabine gets built into their DNA as they divide and blocks the enzyme that copies it, which stops the cancer cells multiplying.

What is it used for?

Haematologists rely on cytarabine for:

• Acute lymphoblastic leukaemia (ALL) in children and adults, as one of several medicines in the plan.
• Acute myeloid leukaemia (AML), both to clear the leukaemia from the bone marrow and, in higher doses, to deepen and hold the remission.
• Chronic myeloid leukaemia that has moved into its blast phase.

Whether you need standard or high-dose cytarabine depends on the type of leukaemia, your age, your genetic test results and how well earlier treatment worked.

How is it given?

Specialist nurses give cytarabine in a hospital or cancer centre. With higher doses it runs as a drip over one to three hours, often twice a day on set days, and staff check your balance, speech and eyes before each dose. Your doctor decides the dose and the number of courses.

Common side effects

• Low white cells, platelets and red cells for some weeks after each course
• Sore, red or watery eyes with higher doses
• Feeling sick, vomiting and mouth sores
• A flu-like reaction with fever, bone pain and rash
• Raised liver tests

Alert your nurse at once if you notice unsteadiness, slurred speech, shaky hands, a temperature of 38°C or more, breathing difficulty or unusual bleeding.

Storage

Keep Cytorox 1000mg in its outer carton below 25°C. Hospital pharmacy staff usually handle storage and prepare the infusion.
