Benefits of Enhertu Injection

Treatment of Stomach cancer
Enhertu 100mg Injection is used in the treatment of HER2-positive stomach cancer, particularly those whose cancer has spread or resisted prior treatments. When administered, Enhertu 100mg Injection specifically seeks out HER2-positive cancer cells, delivering chemotherapy directly into these cells while minimizing damage to healthy tissue. This focused approach slows tumor growth and shrinks tumors, offering patients a new line of defense when standard treatments are no longer effective. It improves disease control and helps enhance the patient's survival and quality of life.

Treatment of Metastatic breast cancer
Enhertu 100mg Injection is an effective treatment, especially for patients whose cancer has spread or continued to grow despite other treatments. It works by attaching to HER2 proteins on cancer cells and delivering chemotherapy straight into these cells. This makes the treatment work better against the cancer while causing less harm to healthy cells nearby. By specifically targeting cancer cells, Enhertu 100mg Injection can help slow down or even shrink the spread of cancer, giving patients a longer time before the disease progresses and improving their quality of life, even in advanced stages.

How to use Enhertu Injection

Your doctor or nurse will give you this medicine. Kindly do not self administer.

How Enhertu Injection works

Enhertu 100mg Injection finds cancer cells that have a lot of the HER2 protein on their surface. These HER2-positive cells grow and multiply faster than normal cells. Once it attaches to the HER2-positive cancer cell, it’s pulled inside. Inside the cancer cell, Enhertu 100mg Injection causes damage and kills the cancer cell directly without affecting nearby healthy cells.

Quick tips

For best results, ensure Enhertu 100mg Injection infusions are received consistently every three weeks without missed doses.
Report any side effects, even mild ones, to your doctor so they can help you prevent or manage them.
Since Enhertu 100mg Injection can lower your white blood cell count, minimizing your exposure to infections is important. Wash your hands frequently, avoid crowded places when possible, and clean any minor cuts or wounds.
Fatigue is a common side effect with Enhertu 100mg Injection, so avoid strenuous activities, especially if your energy levels are low. However, light activities like short walks or stretching can boost energy levels and reduce fatigue.
Drink plenty of water and eat balanced, nutritious meals to help support your immune system.
Cancer treatment can be challenging, so remember that emotional support is just as important as physical care. Reach out to family, friends, or support groups, and let your doctor know if you need additional resources to support your mental health during treatment.
