What is Halaven?

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

Halaven is used to treat breast cancer that has spread to other parts of the body (metastatic).

Halaven is also used to treat liposarcoma, a rare type of cancer that develops in fatty tissue anywhere in the body. It is used for liposarcoma that cannot be treated with surgery, or has spread throughout the body.

Halaven is usually given after at least two other cancer treatments did not work or have stopped working.


Do not use Halaven if you are pregnant. It could harm the unborn baby.

Before you receive Halaven, tell your doctor if you have liver or kidney disease, congestive heart failure, a heart rhythm disorder, a personal or family history of Long QT syndrome, or an electrolyte imbalance (such as low levels of potassium or magnesium in your blood).

Halaven can weaken (suppress) your immune system, and 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, cough, or painful urination).

Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.

Call your doctor at once if you have a serious side effect while taking Halaven such as fever, chills, body aches, flu symptoms, mouth sores, pain or burning when you urinate, pale skin, feeling light-headed or short of breath, fast or uneven heart rate, severe numbness or tingling in your hands and feet, extreme thirst, increased urination, leg discomfort, muscle weakness or limp feeling.

Before taking this medicine

You should not use Halaven if you are allergic to eribulin.

To make sure Halaven is safe for you, tell your doctor if you have ever had:

Eribulin can harm an unborn baby if the mother or the father is using this medicine.

This medicine may affect fertility (ability to have children) in both men and women. However, it is important to use birth control to prevent pregnancy because eribulin can harm an unborn baby.

How is Halaven given?

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

Halaven is given in a 21-day treatment cycle. You may need to use the medicine only during the first 1 to 2 weeks of each cycle. Your doctor will determine how long to treat you with this medicine.

Halaven can weaken (suppress) your immune system, and you may get an infection or bleed more easily. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results.

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