Ontruzant is a biosimilar medication that is used in the treatment of certain types of cancer, including breast cancer and gastric cancer. It is a form of trastuzumab, which is a monoclonal antibody that works by targeting and blocking the HER2 protein on cancer cells. By doing so, Ontruzant helps to slow down the growth and spread of cancer cells in the body.

As a medical professional, I often prescribe Ontruzant to patients who have been diagnosed with HER2-positive breast cancer or gastric cancer. This medication has been shown to be effective in improving outcomes for these patients, including reducing the risk of cancer recurrence and improving overall survival rates.

It is important for patients to follow their treatment plan closely when taking Ontruzant, as it is typically given as an intravenous infusion in a healthcare setting. Patients may experience side effects such as nausea, fatigue, and infusion reactions, but these are usually mild and can be managed with proper medical care.

Before starting treatment with Ontruzant, it is important for patients to discuss their medical history and any other medications they are taking with their healthcare provider. This will help ensure that Ontruzant is the right treatment option for them and that it will not interact negatively with any other medications.

Overall, Ontruzant is a valuable medication in the fight against certain types of cancer, and I am confident in its ability to help my patients achieve positive outcomes in their treatment journey.
