TRASTUZUMAB
About
TRASTUZUMAB is an anti-cancer medicine used in the treatment of HER2-positive Breast cancer and HER2-positive metastatic gastric or gastroesophageal junction adenocarcinoma. Cancer is a disease where the cells grow abnormally and divide uncontrollably. It can also be used when the cancer has spread to other parts of the body.
TRASTUZUMAB contains Trastuzumab as an active ingredient, which belongs to the class of monoclonal antibodies. It works by inhibiting the abnormal growth of cancer cells and, finally, causes the initiation of programmed cell death.
TRASTUZUMAB may cause certain side effects such as abdominal pain, chills, diarrhoea, fatigue, nausea, back pain, bone pain, edema, insomnia, fever, dizziness, headache, vomiting, cough, rash, and injection site reactions. If the side effects persist or bother you, please consult your doctor. TRASTUZUMAB will be administered by a trained doctor. Hence, do not self-administer.
Avoid taking it and inform your doctor if you are allergic to TRASTUZUMAB or its components. Inform your doctor if you have any cardiovascular conditions, lung problems, or liver/kidney disease, as it can cause adverse effects. TRASTUZUMAB is known to cause embryo-fetal toxicity. Hence, if you are pregnant or breastfeeding, inform your doctor beforehand.
Uses of TRASTUZUMAB
Medicinal Benefits
TRASTUZUMAB contains Trastuzumab, which is used for treating patients with HER2-positive breast cancer and HER2-positive metastatic gastroesophageal adenocarcinoma. This medicine works by inhibiting the excess production of a human epidermal growth factor receptor 2 (HER2) protein in the mammalian cells. This causes inhibition of the cancer cell growth and, finally, initiation of programmed cell death.

Habit Forming
Diet & Lifestyle Advise
- Meditation and yoga have been proven very effective in helping cancer patients maintain a healthy attitude and body.
- Eat more lean meats, healthy fats, fruits, vegetables, and whole-grain foods to give you more energy.
- Stay hydrated by drinking plenty of water, as dehydration is often seen in cancers.
- Taking a stroll in the garden or spending 30 minutes of your time doing some light physical activity can be very useful. However, do not over-exert yourself if you feel too tired.
- Avoid smoking and alcohol consumption.
Special Advise
- Avoid intercourse while on treatment with TRASTUZUMAB.
- Regular, complete blood count monitoring is advised during the treatment.
- All patients should be tested for HER2 test before starting the treatment regimen.
- Liver function tests (LFT) and pulmonary function tests (PFT) should be performed before starting the treatment and every 4 to 6 weeks during the treatment.
- Regular ECG and electrolytes should be monitored while taking the medicine.
Patients Concern
Disease/Condition Glossary
Breast Cancer: Breast cancer is a type of cancer with abnormal growth in the cells of the breast. There are different kinds of breast cancer, such as cancer occurring in lobules (glands that produce milk), ducts of the breast (the pathway that brings milk from glands to the nipple), and in the fatty tissue or the fibrous connective tissue within the breast. Symptoms of breast cancer include a lump in the breast, breast pain, redness, swelling, nipple discharge other than breast milk, bloody discharge, a lump or swelling under the arm, unexplained change in shape, size or appearance of the breast, peeling, flaking or scaling of the skin.
Stomach Cancer (Gastric adenocarcinoma): It is a type of cancer that develops from the stomach lining. When the cancer cells spread to other organs of the body, it is called metastatic. This condition can occur mainly due to smoking, a highly processed or salty diet, and severe bacterial infection of H. pylori. Symptoms of stomach cancer include feeling bloated after eating, feeling full after eating small amounts of food, nausea, heartburn or indigestion.
FAQs
TRASTUZUMAB contains Trastuzumab, which works by inhibiting the excess production of a protein called human epidermal growth factor receptor 2 (HER2) in mammalian cells. This causes inhibition of the cancer cell growth.
Inform your doctor whether you have received any other cancer treatment. TRASTUZUMAB may cause a decrease in left ventricular ejection fraction, cardiomyopathy, hypersensitivity reactions, pulmonary toxicity, and embryo-fetal toxicity during the treatment. Hence, inform your oncologist if you have any cardiovascular conditions, liver/kidney disease, lung problems, are pregnant, are planning to become pregnant, or are breastfeeding before receiving TRASTUZUMAB.
