How to use Interferon gamma-1b

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Interferon gamma-1b is injected under the skin. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.

Use only the type of syringe supplied with this medicine, or recommended by your pharmacist. Do not mix interferon gamma-1b in the same syringe with other injectable medicines.

Do not shake the medication bottle. Prepare your dose only when you are ready to give an injection. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

Each single-use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.

Interferon gamma-1b can lower blood cells that help your body fight infections and help your blood to clot. This can make it easier for you to bleed from an injury or get sick from being around others who are ill.

While using interferon gamma-1b, you may need frequent blood tests. Your kidney function may also need to be checked.

Tell your doctor if you have any changes in height or weight. Interferon gamma-1b doses are based on body surface area (height and weight), and any changes may affect your dose.

Store interferon gamma-1b in the refrigerator, do not freeze.

You may take the medicine out of the refrigerator and allow it to reach room temperature before injecting your dose.

Do not leave the medicine at room temperature for longer than 12 hours. Throw the medicine if it has been at room temperature for more than 12 hours. Do not put it back in the refrigerator.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Warnings

Interferon gamma-1b can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, body aches).

What other drugs will affect Interferon gamma-1b

Other drugs may interact with interferon gamma-1b, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
