Why is this medication prescribed?

It is a synthetic form of interferon gamma, which is a naturally occurring protein in the body that helps regulate the immune system. Interferon gamma-1b injection is used for the treatment of two main conditions:

• Chronic granulomatous disease (CGD): CGD is a rare genetic disorder that affects the immune system. People with CGD have a defect in their white blood cells, which makes them more susceptible to recurrent and severe bacterial and fungal infections. Interferon gamma-1b injection is used as an adjunctive therapy to reduce the frequency and severity of infections in patients with CGD.
• Osteopetrosis: Osteopetrosis is a rare inherited disorder characterized by increased bone density and abnormalities in bone development. It can cause various complications, such as bone fractures, vision and hearing problems, and anemia. Interferon gamma-1b injection is used in the treatment of certain forms of osteopetrosis to improve bone marrow function and reduce the incidence of infections.

How should this medicine be used?

However, here is a general overview of how interferon gamma-1b injection is typically used:

• Administration: Interferon gamma-1b is administered as a subcutaneous injection, which means it is injected just under the skin. The injection is usually given by a healthcare professional or under their supervision.
• Dosage: The dosage of interferon gamma-1b will depend on various factors, including the specific condition being treated, the patient’s weight, and their response to the medication. Your healthcare provider will determine the appropriate dosage for you.

• Pregnancy and breastfeeding: Interferon gamma-1b should be used during pregnancy only if the potential benefits outweigh the potential risks to the fetus. It is important to discuss the risks and benefits with your doctor if you are pregnant or planning to become pregnant. It is not known whether interferon gamma-1b passes into breast milk, so caution is advised if you are breastfeeding.
• Other medications: Inform your healthcare provider about all the medications you are currently taking, including prescription drugs, over-the-counter medications, and supplements. Certain medications may interact with interferon gamma-1b, potentially affecting its efficacy or increasing the risk of side effects.
