What is Clolar?

Clolar is a cancer medicine that interferes with the growth and spread of cancer cells in the body. Clolar is used to treat acute lymphoblastic leukemia (a type of blood cancer) in children and young adults up to 21 years old.

Clolar is usually given after other cancer medicines have been tried without successful treatment.

Warnings

Clolar can cause life-threatening side effects including: serious infection, severe skin rash, internal bleeding, and liver or kidney damage.

Call your doctor right away if you have: fever, chills, unusual bleeding or bruising, urination problems, stomach pain or swelling, loss of appetite, bloody diarrhea, coughing up blood, sudden numbness or severe headache, problems with vision or balance, or sudden swelling in your arms, legs and other parts of the body.

Clolar can harm your liver or kidneys. Call your doctor if you have lower back pain, little or no urinating, or blood in your urine.

How should I take Clolar

Clolar is injected into a vein through an IV. A healthcare provider will give you this injection.

Clolar is usually given daily for 5 days in a row during one or more 1-month treatment cycles. Your doctor will determine how many treatment cycles you will receive and how often.

You may receive other medications to help prevent certain side effects of Clolar.

Clolar can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your kidney or liver function may also need to be tested. Your cancer treatments may be delayed based on the results of these tests.

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your Clolar injection.

What happens if I overdose?

Since Clolar is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
