What is the most important information I should know about nelarabine (Arranon)?

Nelarabine may cause serious side effects of the central nervous system, such as problems with balance, coordination, or fine motor skills. These symptoms may not go away even after you stop receiving nelarabine. Talk with your doctor if you have concerns about any possible long-term side effects.

Before you receive nelarabine, tell your doctor if you have liver or kidney disease, a nerve disorder, a history of chemotherapy or radiation treatment of your head, neck, or spinal cord.

Nelarabine can lower blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood will need to be tested often. Visit your doctor regularly.

Do not receive a "live" vaccine while you are being treated with nelarabine, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you.

Nelarabine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
