Interferon Gamma-1b

This medication is primarily used to reduce the frequency of serious infections in patients with chronic granulomatous disease (CGD), a rare genetic disorder affecting the immune system's ability to fight certain bacteria and fungi. It is also indicated for reducing serious infection risk in patients with malignant osteopetrosis, a rare bone disorder characterized by abnormally dense bone formation.

Interferon Gamma-1b is a recombinant form of interferon gamma, a naturally occurring cytokine. It works by enhancing the activation and function of macrophages, improving phagocytic activity, and increasing the production of reactive oxygen species that help eliminate pathogens. This immunomodulatory action strengthens the body's natural defenses against specific infections.

This medication is administered by subcutaneous injection, typically three times per week. Common side effects include flu-like symptoms such as fever, chills, headache, and muscle aches, as well as injection site reactions and rash. Patients should be monitored for signs of infection and liver function during treatment. It should be used with caution in patients with seizure disorders, cardiac disease, or compromised bone marrow function.
