Warnings

Get emergency medical help if you notice signs of an allergic reaction: hives; trouble breathing; feeling faint; swelling of your face, lips, tongue, or throat.

Onxol can reduce the number of blood cells that help your body fight infections and help your blood clot. This may make you more likely to get an infection or bleed easily. Call your doctor if you experience unusual bruising or bleeding, or signs of infection (fever, sore throat, mouth sores, cough).

How is Onxol given?

Onxol is given as an infusion into a vein. A healthcare provider will give you this injection.

Onxol must be given slowly, and the infusion can take 3 to 24 hours to complete.

Onxol is usually given once every 2 to 3 weeks. Follow your doctor's dosing instructions very carefully.

You may be given other medications to prevent an allergic reaction while you are receiving Onxol.

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?

Do not be near people who are sick or have infections. Tell your doctor right away if you notice any signs of infection.

Avoid activities that may increase your risk of bleeding or injury. Take extra care to prevent bleeding while shaving or brushing your teeth.
