Herzuma Overview
Herzuma is a prescription medication used to treat adults with certain types of breast cancers and stomach cancer in which human epithelial growth factor receptor (HER2) is overexpressed.
Herzuma, a monoclonal antibody, belongs to a group of drugs called HER2/neu receptor antagonists. HER2 is found in large amounts on the surface of some cancer cells where it promotes their growth. When Herzuma binds to HER2 it stops the growth of such cells and causes them to die.
This medication is available in an injectable form to be given directly into a vein (IV) by a healthcare professional. For early breast cancer, metastatic breast cancer and metastatic gastric cancer, Herzuma is given every 3 weeks. Herzuma may also be given once a week for metastatic breast cancer.
Common side effects of Herzuma include fever, chills, headache, diarrhea, nausea, chills, congestive heart failure, insomnia, cough, and rash.
