What HERCEPTIN SC is given for

HERCEPTIN SC contains an active ingredient called trastuzumab.

HERCEPTIN SC belongs to a group of medicines known as anti-neoplastic (or anti-cancer) agents. There are many different classes of anti-neoplastic agents.HERCEPTIN SC belongs to a class called monoclonal antibodies.

Monoclonal antibodies are proteins made in a laboratory. These proteins aredesigned to recognise and bind to other unique proteins in the body.

HERCEPTIN SC binds selectively to a protein called human epidermalgrowth factor receptor 2 (HER2). HER2 is found in large amounts on the surface ofsome cancer cells. When HERCEPTIN SC binds to HER2 receptors it stops the growth and spread of the cancer cells.

HERCEPTIN SC is used to treat breast cancer whose tumour has tested positive to HER2.

HERCEPTIN may be used alone or in combination with other medicines that treat breast cancer, such as an aromatase inhibitor (hormone receptor positive breast cancer) or a taxane (e.g. paclitaxel or docetaxel).

For further information about the other medicines you are receiving with HERCEPTIN SC, please ask your doctor, nurse or pharmacist for the CMI leaflet.

Ask your doctor if you have any questions why HERCEPTIN SC has been prescribed for you. This medicine is available only with a doctor's prescription.
