Halaven - patient leaflet, side effects, dosage

1. What HALAVEN is and what it is used for

HALAVEN contains the active substance eribulin and is an anti-cancer medicine which works by stopping the growth and spread of cancer cells.

It is used in adults for locally advanced or metastatic breast cancer (breast cancer that has spread beyond the original tumour) when at least one other therapy 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.

Pregnancy, breast-feeding and fertility

HALAVEN may cause serious birth defects and should not be used if you are pregnant unless it is thought clearly necessary after carefully considering all the risk to you and the baby. It may also cause future permanent fertility problems in men if they take it and they should discuss this with their doctor before starting treatment. Women of childbearing age should use effective contraception during and up to 3 months after treatment with HALAVEN.

HALAVEN must not be used during breast-feeding because of the possibility of risk to the child.

3. How to use HALAVEN

HALAVEN will be given to you by a qualified healthcare professional as an injection into a vein, over a period of 2 to 5 minutes. The dose you will receive is based on your body surface area (expressed in squared metres, or m2) which is calculated from your weight and height. The usual dose of HALAVEN is 1.23 mg/m2, but this may be adjusted by your doctor based on your blood test results or other factors. To ensure that the whole dose of HALAVEN is given it is recommended that a saline solution is flushed into the vein after HALAVEN is given.

How often will you be given HALAVEN?

HALAVEN is usually given on Days 1 and 8 of every 21-day cycle. Your doctor will determine how many cycles of treatment you should receive. Depending on the results of your blood tests, the doctor may need to delay administration of the medicine until the blood tests return to normal. The doctor may also then decide to reduce the dose you are given.

If you have any further questions about the use of this medicine, ask your doctor.
