What is tbo-filgrastim?

Tbo-filgrastim is a man-made form of a protein that stimulates the growth of white blood cells in your body. White blood cells help your body fight against infection.

Tbo-filgrastim is used to reduce the duration of severe neutropenia, a lack of certain white blood cells caused by receiving chemotherapy with certain cancer medications.

Tbo-filgrastim is for use in adults and children who are least 1 month old.

Warnings

How is tbo-filgrastim given?

Prepare your injection only when you are ready to give it. Do not shake the prefilled syringe. Do not use if the medicine has particles in it. Call your pharmacist for new medicine.

The first dose of tbo-filgrastim is usually given within 24 hours after your chemotherapy dose. You will receive daily injections until your blood cell counts return to normal.

You should not inject tbo-filgrastim within 24 hours before your next chemotherapy dose.

Store in the refrigerator, do not freeze. Protect from light.

Take the medicine out of the refrigerator and let it reach room temperature for 30 minutes before injecting your dose. Do not leave the medicine out for longer than 5 days.

Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
