Cancer Home > Trastuzumab Drug Information
If you have been diagnosed with breast cancer or stomach cancer, your healthcare provider may recommend a drug called trastuzumab (Herceptin®). This product is part of a group of medications called monoclonal antibodies.
As a type of biologic therapy, trastuzumab is less "toxic" than chemotherapy. However, it is not suitable for everyone. In fact, this drug is only used to treat cancers that have a high concentration of HER2 receptors. (HER2 is a protein on the outside of certain cancer cells.)
The medication is given intravenously (through an IV). Depending on your dosing regimen, it is given every seven days or every three weeks, depending on certain factors.
