Trastuzumab IV

Trastuzumab IV Uses

Trastuzumab is used alone or with other medications to treat certain types of breast cancer (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.

How To Use Trastuzumab IV

This medication will be given by a health care professional. It is mixed in a solution and given slowly by vein (IV), usually once a week or as directed by your doctor. Your first infusion will be given over at least 90 minutes.

Do not mix with IV fluids that contain dextrose. When mixed with IV fluids, this product will be colorless or clear yellow. Check this product visually for particles or discoloration before use. If either is present, do not use the liquid. Do not shake the IV liquid.

The dose, the speed of your injection, and the length of time you receive trastuzumab depends on your body weight, condition, other treatments, and response to trastuzumab treatment.

To get the most benefit from this medication, do not miss any doses. To help you remember, mark the days on the calendar when you need to receive the medication.

Your doctor may prescribe other medications (e.g., acetaminophen, diphenhydramine) for you to take before the start of your treatment to help prevent serious side effects.
