HALAVEN contains the active ingredient eribulin mesilate.

HALAVEN belongs to a group of medicines called Anti-cancer agents. It works by stopping the growth and spread of cancer cells.

HALAVEN is used for the treatment of breast cancer. It is used when at least one other therapy for locally advanced or metastatic breast cancer (i.e.; breast cancer that has spread beyond the original tumour) has been tried but has lost its effect.

It is also used in adults for advanced or metastatic liposarcoma (a type of cancer that arises from fat tissue) when previous therapy has been tried but has lost its effect.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.
