Trabectedin Injection

pronounced as (tra bek' te din)

Why is this medication prescribed?

Trabectedin injection is used to treat liposarcoma (a cancer that begins in fat cells) or leiomyosarcoma (a cancer that begins in smooth muscle tissue) that has spread to other parts of the body and cannot be treated with surgery in people who have already been treated with certain chemotherapy medications. Trabectedin is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in your body.

How should this medicine be used?

Trabectedin injection comes as a powder to be mixed with liquid to be injected over 24 hours intravenously (into a vein) by a doctor or nurse in a medical facility. It is usually given once every 3 weeks for as long as your doctor recommends that you receive treatment.

Your doctor may delay or stop your treatment with trabectedin injection depending on your response to the medication and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment.

Your doctor will probably prescribe a medication for you to take before you receive each dose of trabectedin to help prevent side effects.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
