Keytruda 100mg Injection is an advanced immunotherapy medicine that works by strengthening your body’s own immune system to recognize and fight cancer cells more effectively. It is widely used in the treatment of several types of cancer, including cancers of the lung, skin, bladder, stomach, liver, cervix, kidney, colon, rectum, as well as head and neck cancers and classical Hodgkin lymphoma. Many patients experience long-lasting benefits with this treatment, although results can vary from person to person and some side effects may occur.

Keytruda 100mg injection is administered through an intravenous (IV) infusion by a trained healthcare professional, with the dose and treatment schedule tailored to your specific cancer type and overall health. Since the benefits may take time to appear, it is important to continue treatment exactly as advised by your doctor and not stop it on your own. Common side effects can include fatigue, rash, fever, nausea, muscle pain, or infusion-related reactions such as chills or breathing discomfort. Inform your doctor about any existing medical conditions and medicines you are taking. Keytruda is not recommended during pregnancy or breastfeeding, and effective contraception should be used during treatment and for a few months afterward.

Keytruda 100mg Injection works by blocking the PD-1 pathway, a mechanism cancer cells use to hide from the immune system. By inhibiting this pathway, it activates and strengthens the body’s T-cells, allowing them to recognize and attack cancer cells more effectively. This immune-based action can slow tumor growth, shrink existing tumors, and help achieve longer-lasting responses in several types of advanced cancers.
