Why is this medication prescribed?

Halaven (generic name eribulin) is a prescription medication used in the treatment of certain types of cancer. Specifically, it is indicated for the treatment of metastatic breast cancer in patients who have previously received at least two types of chemotherapy that included an anthracycline and a taxane.

Halaven belongs to a class of drugs called microtubule inhibitors. It works by inhibiting the growth of cancer cells, thereby slowing down or stopping the spread of cancer in the body.

How should this medicine be used?

The specific dosage and administration of Halaven can vary depending on factors such as the individual’s overall health, the type and stage of cancer being treated, and other medications they may be taking. It is typically administered as an intravenous (IV) infusion, meaning it is injected directly into a vein. The infusion is usually given over a period of 2 to 5 minutes on days 1 and 8 of a 21-day treatment cycle.

It is important to follow the instructions provided by the prescribing healthcare professional and to adhere to the prescribed dosage and treatment schedule. They will determine the appropriate dosage for each individual based on their specific circumstances.

If you or someone you know is prescribed Halaven, it is crucial to consult with a healthcare professional, such as an oncologist or a pharmacist, to receive personalized guidance and further information regarding its use and any potential side effects.
