• cytarabine strongly reduces blood cell production in the bone marrow and your blood cell numbers can continue to fall for up to a week after stopping treatment. Your doctor will test your blood regularly and examine your bone marrow if required
• if your bone marrow is still recovering from the effects of other medicines (your doctor will only consider treatment with cytarabine if absolutely necessary)

Your doctor may prescribe local steroids (anti-inflammatory medicines) to reduce effects on the eyes such as sore eyes with bleeding (haemorrhagic conjunctivitis).
Cytarabine may lead to changes in your blood cells. Your doctor will take blood samples to monitor for these and also to check how well your liver and kidneys are working.
Sometimes the following side effects can occur together, usually 6-12 hours after receiving cytarabine:
