Is HALAVEN® right for me?

HALAVEN is a prescription medicine for adults with metastatic breast cancer (mBC) who have already received at least 2 other types of anticancer medicines for their breast cancer once it has spread to other parts of the body. Previous therapy should have included an anthracycline and a taxane for either early or advanced breast cancer.

When used alone after 2 prior chemotherapies for mBC, HALAVEN is the only chemotherapy that has been proven in a clinical trial to help some women live longer. Although some women lived longer and some women did not live as long, women who were treated with HALAVEN in a clinical trial lived an average of 13.2 months compared with women treated with other chemotherapy or hormone therapy, who lived an average of 10.6 months.

HALAVEN was studied in women with all types of tumor receptors. This means that their ER/PR hormone receptors (estrogen/progesterone receptors) were either positive or negative and their HER2 receptors (human epidermal growth factor receptor 2) were either positive or negative.

What safety information do I need to know about HALAVEN?

  • Low white blood cell count (neutropenia). This can lead to serious infections that could lead to death. Your health care provider will check your blood cell counts. Call your health care provider right away if you develop fever (temperature above 100.5°F), chills, cough, or burning or pain when you urinate, as any of these can be symptoms of infection
  • Numbness, tingling, or pain in your hands or feet (peripheral neuropathy). Peripheral neuropathy is common with HALAVEN and sometimes can be severe. Tell your health care provider if you have new or worsening symptoms of peripheral neuropathy
  • Your health care provider may delay or decrease your dose or stop treatment with HALAVEN if you have side effects

Before you receive HALAVEN, tell your health care provider about all of your medical conditions, including if you

  • have liver or kidney problems

Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

What are the possible side effects of HALAVEN?

The most common side effects of HALAVEN in adults with breast cancer include low white blood cell count (neutropenia), low red blood cell count (anemia), weakness or tiredness, hair loss (alopecia), nausea, and constipation.

Your health care provider will do blood tests before and during treatment while you are taking HALAVEN.
