What is trabectedin?

Trabectedin is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Trabectedin is used to treat liposarcoma, a rare type of cancer that grows in fatty tissues of the body.

Trabectedin is also used to treat leiomyosarcoma, a rare fast-growing type of cancer that grows in many tissues of the body, including fat, muscle, bone, joints, and blood vessels.

Trabectedin is used to treat cancer that has spread to other parts of the body or cannot be treated with surgery.

Trabectedin may also be used for purposes not listed in this medication guide.

How is trabectedin given?

Before you receive a dose of trabectedin, you may need a blood test to check your liver function.

Trabectedin is given as an infusion into a vein, through a central line IV. A healthcare provider will give you this injection.

Trabectedin must be given slowly and the infusion can take up to 24 hours to complete.

Trabectedin is usually given once every 3 weeks. Your doctor will determine how long to treat you with trabectedin.

You may be given steroid medication to prevent certain side effects of trabectedin.

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

Trabectedin affects your immune system. You may get infections more easily, even serious or fatal infections. Your doctor will need to examine you on a regular basis.

Your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your trabectedin injection.

What happens if I overdose?

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

What should I avoid while receiving trabectedin?

Grapefruit may interact with trabectedin and lead to unwanted side effects. Avoid the use of grapefruit products.
