Sigrima 420mg Injection is a targeted treatment specially designed for HER2-positive breast cancer. It contains pertuzumab, a monoclonal antibody that works by attaching to specific receptors on cancer cells, slowing or stopping their growth. The injection is given into a vein by a healthcare professional, and the dosage depends on your individual condition, whether the cancer is early stage, has come back, or has spread to other parts of the body.

Like most cancer treatments, Sigrima may cause some side effects. Patients often experience tiredness, nausea, diarrhea, or hair loss. It can also affect the bone marrow, which may reduce white blood cell counts and increase the risk of infections. Regular check-ups and blood tests are important during treatment to keep track of your heart, liver, kidney, and blood health. Even if side effects occur, it’s important to continue treatment as advised by your doctor to get the best results.

Before starting Sigrima, let your doctor know if you have heart problems, past radiotherapy, or any allergies. This medicine is not recommended for children, and it should be avoided during pregnancy and breastfeeding. Both men and women are advised to use contraception during and after treatment. When used alongside chemotherapy, Sigrima has been shown to reduce the chances of cancer returning and improve survival outcomes for people with HER2-positive breast cancer.

Sigrima 420mg Injection targets the HER2 protein, which is overexpressed in certain breast cancer cells and promotes their growth. By binding specifically to HER2 receptors on the surface of these cancer cells, Sigrima blocks the transmission of growth signals, thereby inhibiting the proliferation of cancer cells.
