Cytarabine is given intravenously. Sometimes it is given as a shot under the skin or directly into the spinal fluid. It can be given in a low, average, or high dose.
How It Works
Cytarabine is classified as an antimetabolite. It kills cancer cells by interfering with the way they multiply.
Why It Is Used
How Well It Works
Cytarabine is an effective antitumor drug. But the type and extent of a cancer determines how well this drug slows or stops the growth of cancer cells in the body.
Cytarabine is often combined with other drugs.
Cytarabine is often given with another medicine called dexamethasone. This is done to prevent a possibly fatal side effect called chemical arachnoiditis. This causes symptoms that include nausea, vomiting, headache, and fever. Your doctor will watch you closely when you are given cytarabine.
Other side effects that are common with cytarabine include:
- Decreased white blood cell counts (leukopenia) and red blood cell counts (anemia).
- Decreased platelet counts (thrombocytopenia), which may lead to bleeding in the digestive tract causing tarry stools. It may also cause bleeding under the skin, in the urine, or other places in the body.
- Nausea, vomiting, and loss of appetite.
- Headaches or seizures.
- Hair loss. This is reversible, and hair will grow back when treatment ends.
- Mouth sores (stomatitis).
- Slurred speech and difficulty walking (ataxia).
Peripheral neuropathies, which may be irreversible and
may be made worse by exercise. Symptoms include:
- Numbness and tingling.
- Unsteadiness when standing or walking.
- Clumsiness of the hands and feet.
- Cough and hoarseness.
- Eye problems, such as blurred vision or the inability to see colors.
- Kidney damage.
