Product introduction
Kadcyla 160mg Injection is given as an injection by a qualified medical professional. Your doctor will decide what dose is necessary and how often you need to take it. This will depend on what you are being treated for and may change from time to time. You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to.
The most common side effects of this medicine include tiredness, nausea, musculoskeletal (bone, muscle or joint) pain, and bleeding. This medicine may reduce the number of blood cells (decrease red blood and white blood cells) in your blood, thereby, increasing the susceptibility to infections. Regular blood tests are required to check your blood cells along with heart, liver, and blood uric acid levels.
Before taking it, tell your doctor if you have heart disease, liver, or kidney problems or are taking any medicines to treat infections. Many other medicines can affect, or be affected by, this medicine so let your healthcare team know all medications you are using. This medicine is not recommended during pregnancy or while breastfeeding. The use of effective contraception by both males and females during treatment is important to avoid pregnancy.
There is a Patient Support Program/Patient Assistance Program available in India for this medicine, being managed by Tata 1mg. Please contact your prescribing doctor to know more about the same. You may also call on (1800-102-1618) for more details.

Benefits of Kadcyla Injection
Kadcyla 160mg Injection is used to treat HER2-positive early breast cancer when some cancer remains after chemotherapy and HER2-targeted treatment given before surgery. It helps destroy remaining cancer cells and reduces the risk of cancer returning. This medicine works by targeting cancer cells that have a protein called HER2 on their surface. Your doctor will monitor your response to treatment and manage any side effects that may occur.
Kadcyla 160mg Injection is used to treat HER2-positive breast cancer that has spread to other parts of the body (metastatic breast cancer). It is prescribed to patients who have previously received certain cancer treatments, including trastuzumab and taxane-based chemotherapy.
