What Is Vivitra 150 mg Injection?
Vivitra 150 mg injection contains Trastuzumab, made by Zydus. It comes as a powder that gets mixed into a solution before use. Trastuzumab belongs to a group of medicines called monoclonal antibodies. These are lab-made proteins built to lock onto one specific target in the body.
Who Needs This Trastuzumab Injection?
This medicine treats cancers where cells carry too much of a protein called HER2 on their surface. HER2 pushes cancer cells to grow and divide faster than normal.
Vivitra 150 mg inj is used for:
- HER2-positive breast cancer
- HER2-positive stomach (gastric) cancer
Doctors check HER2 levels with a lab test before recommending this medicine. Not every breast or stomach cancer responds to it, so this testing step matters.
How Does Vivitra 150 mg Injection Work in the Body?
Trastuzumab attaches itself to HER2 on the surface of cancer cells. Once attached, it blocks the growth signal HER2 sends. This slows down how fast the cancer cell multiplies. At the same time, it marks the cell so your own immune system can find it and clear it out. This two-part action is why doctors often combine it with other cancer drugs.

Who Should Avoid This Injection?
Pregnant women should not take Vivitra 150 mg injection. It can harm the unborn baby. Women who can become pregnant should use birth control during treatment and for several months after the last dose.
- People with existing heart disease need a heart function test before starting. Trastuzumab can affect heart muscle over time.
- People with lung disease should tell their doctor beforehand. Breathing problems have been reported during infusion.
- Anyone with a known allergy to Trastuzumab or any ingredient in this injection should not use it.
Doctors usually run regular heart scans during the treatment course to catch any change early.
How to store Vivitra 150 mg injection properly?
- Keep the unopened vial in a refrigerator between 2°C and 8°C.
- Do not freeze it, and keep it away from direct light.
- Once the powder is mixed into solution, use it within the time your pharmacist or doctor advises.
- Keep it refrigerated until then.
A vial left out at room temperature for too long should not be used. The protein in the medicine can break down if coldchain breaks before the injection is to be used.
This drug is sensitive to temperature swings during transport. Even a short break in the cold chain can affect how well the injection works later.
