You should not use this medication if you are allergic to it.
If you have liver or kidney disease or a bone marrow problem, you may need a dose adjustment or special tests to safely receive cladribine.
FDA pregnancy category D. Cladribine can cause harm to an unborn baby or cause birth defects. Before you receive cladribine, tell your doctor if you are pregnant. Use effective birth control to prevent pregnancy while you are receiving cladribine.
It is not known whether cladribine passes into breast milk or if it could harm a nursing baby. Do not breast-feed while you are receiving cladribine.
Cladribine is given as an injection through a needle placed into a vein. You will receive this injection in a clinic or hospital setting.
Cladribine must be given slowly through an IV infusion, and you will receive it around the clock for 7 days in a row. Your doctor will determine how many 7-day treatments you will receive and how often.
You may receive other medications to help prevent certain side effects of cladribine.
Cladribine can lower the 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.
To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. Your cancer treatments may be delayed based on the results of these tests. Your kidney or liver function may also need to be tested. Do not miss any follow-up visits to your doctor.
Contact your doctor at once if you develop signs of infection such as fever, chills, sore throat, flu symptoms, pale skin, easy bruising or bleeding (nosebleeds, bleeding gums), purple or red pinpoint spots under your skin, loss of appetite, mouth sores, or unusual weakness.
