Onco Bcg 40mg Injection is a biological immunotherapeutic and vaccine preparation containing a live, attenuated strain of Mycobacterium bovis. It plays a vital role in the prevention of tuberculosis (TB) and the treatment of non-muscle-invasive bladder cancer (NMIBC).

This injection works by stimulating the body’s immune defense mechanisms to identify and destroy infectious agents and abnormal cancerous cells. As a vaccine, it builds strong immunity against Mycobacterium tuberculosis. As an immunotherapy, it activates local immune responses in the bladder to prevent tumor recurrence after surgical treatment.
