Trastuzumab may lead to serious heart problems, including heart failure. The risk of heart problems is increased if you also use an anthracycline (e.g., doxorubicin). Your doctor may need to stop this medication if heart problems occur.
Trastuzumab use may sometimes result in a serious reaction to the IV infusion with serious lung problems. If these problems occur, they usually happen while the drug is being given or within 24 hours of the dose. If you have trouble breathing or severe dizziness/fainting, tell your doctor or pharmacist immediately because your IV infusion may need to be stopped.
Trastuzumab can cause serious (possibly fatal) harm to an unborn baby if used during pregnancy.
USES: Trastuzumab is used alone or with other medications to treat certain types of breast cancer. It is also used along with other medications to treat certain types of stomach cancer. The types of cancers trastuzumab is used to treat are tumors that produce more than the normal amount of a certain substance called HER2 protein.This medication is called a monoclonal antibody. It works by attaching to the HER2 cancer cells and blocking them from dividing and growing. It may also destroy the cancer cells or signal the body (immune system) to destroy the cancer cells.
