Description

Pertuzumab injection is used to treat breast cancer that has spread to other parts of the body. It is used together with other cancer medicines, docetaxel and trastuzumab, and only in patients with HER2-positive breast cancer. The HER2 protein is produced by some breast tumors. Pertuzumab interferes with the growth of this protein, which is eventually destroyed by the body. It is a monoclonal antibody.

This medicine is to be administered only by or under the immediate supervision of your doctor.

This product is available in the following dosage forms:

Precautions

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects. Be sure to keep all appointments.

This medicine may cause heart failure. Your doctor will test your heart before you start receiving pertuzumab. The test will be repeated every few months while you are receiving the medicine. Check with your doctor right away if you have chest pain, trouble breathing, rapid weight gain, or abnormal swelling in your ankles or legs. These could be symptoms of heart failure.

This medicine may cause a serious infusion reaction. This can be life-threatening and requires immediate medical attention. Tell your doctor or nurse right away if you have a fever, chills, chest pain, lightheadedness, dizziness, fainting, a headache, a rash, pain, nausea, vomiting, trouble breathing, or weakness within a few hours after the infusion.

Cancer medicines can cause nausea or vomiting in most people, sometimes even after receiving medicines to prevent it. If this happens, ask your doctor or nurse about other ways to control these side effects.
