What is Onxol?

Onxol is used to treat breast cancer, ovarian cancer, and lung cancer. It is also used to treat AIDS-related Kaposi's sarcoma.

Important Information

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; feeling like you might pass out; swelling of your face, lips, tongue, or throat.

Onxol can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, tiredness).

Before taking this medicine

You should not be treated with Onxol if you are allergic to it, or if you have:

  • low white blood cell (WBC) counts; or

  • an allergy to castor oil (contained in Onxol and other medicines such as cyclosporine or teniposide).

Tell your doctor if you have ever had:

Onxol may harm an unborn baby. Use effective birth control to prevent pregnancy, and tell your doctor if you become pregnant.

You should not breast-feed while you are using Onxol.

How is Onxol given?

Onxol is injected into a vein through an IV. A healthcare provider will give you this injection. You may be given other medications to prevent an allergic reaction while you are receiving this medicine.

Onxol is usually given once every 3 weeks. Follow your doctor's dosing instructions very carefully.

Your breathing, blood pressure, oxygen levels, kidney function, and other vital signs will be watched closely while you are receiving Onxol.

Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when Onxol is injected.

Onxol 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 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 Onxol.

What happens if I overdose?

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

What should I avoid while using Onxol?

Onxol contains alcohol and may cause a drunken feeling when the medicine is injected into your vein. Avoid drinking alcohol on the day of your this medicine injection.
