Interferon Gamma-1b Injection

Interferon gamma-1b injection is used to reduce the frequency and severity of serious infections in people with chronic granulomatous disease (an inherited immune system disease). It is also used to slow down worsening of their condition in people with severe, malignant osteopetrosis (an inherited bone disease). Interferon gamma-1b is in a class of medications called immunomodulators. It is not known exactly how interferon gamma-1b works to treat chronic granulomatous disease and osteopetrosis.

🔔 How should this medicine be used?

Interferon gamma-1b injection comes as a solution to inject subcutaneously (just under the skin) three times a week, for example, every Monday, Wednesday, and Friday. Inject interferon gamma-1b injection at around the same time of day each time you inject it. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use interferon gamma-1b injection exactly as directed. Do not inject more or less of it or inject it more often than prescribed by your doctor.

You will receive your first dose of interferon gamma-1b in your doctor’s office. Then you can inject interferon gamma-1b yourself or have a friend or relative give the injections. Before you use interferon gamma-1b yourself the first time, read the written instructions that come with it. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it.

Never reuse or share syringes, needles, or vials of medication. Throw away used needles and syringes in a puncture-resistant container and throw away used vials of medication in the trash. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.

You can inject interferon gamma-1b in your upper arms, stomach area, or your thighs. Choose a different spot each time you inject your medication. Do not inject your medication into skin that is irritated, bruised, reddened, infected, or scarred.

Your doctor or pharmacist will give you the manufacturer’s patient information sheet when you begin treatment with interferon gamma-1b and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions.

The problem isn’t a shortage of people wanting to be doctors, but rather, too few opportunities for training. Medical schools have increased class sizes by 30% since 2002, but federal funding for residency training – an essential step in the process of becoming a practicing physician – has not increased since 1997, according to Inside Higher Ed.
