Cytarabine
About Cytarabine
Cytarabine is a prescription injection used to treat certain types of blood cancers, such as acute myeloid leukaemia and acute lymphocytic leukaemia. It is also used to treat or prevent cancer that has spread to the tissues covering the brain and spinal cord. This medicine works by targeting and stopping the growth of abnormal cancer cells in the body.
Because this medicine is given as an injection, a healthcare professional will give it to you in a hospital or clinic setting. The frequency of your treatment will depend on your specific condition and how well your body responds. Since it is given by injection, you do not need to worry about taking it with or without food, but staying well-hydrated before your appointments can help. Eating small, frequent, bland meals and avoiding raw foods can support your recovery during treatment.
Like all cancer treatments, Cytarabine can cause some unwanted effects, such as nausea, temporary hair loss, or mouth sores. These are common and usually manageable, but you must contact your doctor immediately if you experience signs of infection, like a fever or chills.
Do not take this if you have had a severe allergic reaction to it in the past. Before starting, talk to your doctor if you have a history of liver damage, kidney disease, or blood disorders, as these conditions may require special monitoring or adjustments to your treatment.
It is important to discuss all other medicines you are taking, as some can increase the risk of side effects when combined with Cytarabine. Avoid drinking alcohol and smoking, as they can worsen liver strain and general side effects. If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare team immediately, as this medicine can harm an unborn baby.
Uses of Cytarabine
Medicinal Benefits
Cytarabine helps control certain blood cancers by slowing the growth and multiplication of abnormal cancer cells. This supports disease control, promotes remission in suitable patients, and allows healthy blood cells to recover during treatment.
- Helps control blood cancers: Slows the growth and spread of rapidly dividing cancer cells, helping manage conditions such as leukaemia and lymphoma.
- Supports remission: By reducing the number of abnormal cancer cells, it may help achieve or maintain remission when used as part of an appropriate treatment plan.
- Allows healthy blood cells to recover: As cancer cells are reduced, the bone marrow can gradually restore the production of normal red blood cells, white blood cells, and platelets.
- Treats cancer involving the central nervous system: When administered into the spinal fluid (intrathecally), Cytarabine delivers treatment directly to the brain and spinal cord, helping control cancer cells in areas that intravenous chemotherapy may not adequately reach.

- Avoid live vaccines: Do not receive live vaccines during treatment unless your doctor specifically advises you to, as your immune system may not respond normally.
- Attend regular monitoring: Keep all scheduled appointments for blood tests so your doctor can monitor your blood cell counts, kidney function, liver function, and overall response to treatment.
Drug Interactions
- Live vaccines: Taking Cytarabine while receiving live vaccines may increase your risk of developing a severe infection from the vaccine.
- Digoxin: Cytarabine may lower the absorption of digoxin tablets, making your heart medication less effective.
- Other chemotherapy drugs: Combining this medicine with other cancer treatments can increase the risk of serious side effects, such as low blood counts and liver strain.

Habit Forming
Diet & Lifestyle Advise
- Practice strict food safety: Because this medicine can lower your white blood cell count, avoid raw or undercooked foods, wash all fruits and vegetables thoroughly, and ensure all dairy products are pasteurized to prevent infections.
- Stay hydrated: Drink plenty of water throughout the day to help your kidneys flush out the waste products of destroyed cancer cells and to help manage nausea.
- Eat soft, bland foods: To prevent mouth sores, opt for soft foods like yogurt, mashed potatoes, and well-cooked vegetables. Avoid spicy, salty, or highly acidic foods.
- Use a soft toothbrush: Brush your teeth gently with a soft-bristled toothbrush to protect your gums from bleeding when your platelet counts are low.
- Wash your hands frequently: Keep your hands clean and avoid crowded areas or contact with people who are sick to protect yourself from infections.
Special Advise
- Regular blood tests are recommended while taking Cytarabine to monitor the number and type of cells in the blood.
- Cytarabine, like other cytotoxic medicines, can cause hyperuricemia due to the fast lysis of neoplastic cells. Blood uric acid levels should be monitored and be ready to utilize any supportive or pharmacologic interventions that may be required to address this condition.
