Trastuzumab injection is a medication used to treat certain types of breast, stomach, and esophageal cancer. It is a monoclonal antibody, which is a type of drug that targets and attacks specific cells. Trastuzumab works by attaching to a protein called HER2, which is found in large amounts on the surface of some cancer cells. This prevents the HER2 protein from sending signals that tell the cancer cells to grow and divide.
Trastuzumab is usually given as an injection into a vein (intravenous infusion) once every 3 weeks. It can also be given as an injection under the skin (subcutaneous injection) once every week. The dosage of trastuzumab depends on the type and stage of cancer being treated, as well as the patient's weight and other medical conditions.
The most common side effects of trastuzumab include fatigue, nausea, headache, diarrhea, and chills. More serious side effects can occur, such as heart problems, infection, and allergic reactions.
