Important information about Gamunex

Gamunex can be harmful to the kidneys, and these effects are increased when Gamunex is used together with other medicines that can harm the kidneys. Before using Gamunex, tell your doctor about all other medications you use. Many other drugs (including some over-the-counter medicines) can be harmful to the kidneys.

Before you use Gamunex, tell your doctor if you have kidney disease, diabetes (especially if you use insulin), a history of stroke or blood clot, heart disease, high blood pressure, a condition called paraproteinemia, or if you are over 65 years old.

To be sure Gamunex is helping your condition and is not causing harmful effects, your blood will need to be tested on a regular basis. Your kidney function may also need to be checked. Do not miss any scheduled appointments.

Using Gamunex can cause you to have unusual results with certain blood glucose tests. Tell any doctor who treats you that you are using Gamunex.

Gamunex is made from human plasma (part of the blood) and may contain viruses and other infectious agents that can cause disease. Although Gamunex is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using Gamunex.

What should I discuss with my health care provider before using Gamunex?

You should not use Gamunex if you have ever had an allergic reaction to an immune globulin or if you have immune globulin A (IgA) deficiency with antibody to IgA.

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before you use Gamunex, tell your doctor if you have:

kidney disease;
diabetes (especially if you use insulin);
a history of stroke or blood clot;

a condition called paraproteinemia; or

How is Gamunex given?

Use Gamunex exactly as it was prescribed for you. Do not use it in larger doses or for longer than recommended by your doctor. Follow the directions on your prescription label.

Gamunex is given as an injection through a needle placed into a vein. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to use your medicine at home. Do not self-inject Octagam if you do not fully understand how to give the injection and properly dispose of needles, IV tubing, and other items used in giving the medicine.

Gamunex is usually given every 3 to 4 weeks. Your dosing schedule may be different. Follow your doctor's instructions.

Using Gamunex can cause you to have unusual results with certain blood glucose tests. Tell any doctor who treats you that you are using Gamunex.

Do not use the medication if it has changed colors or has any particles in it. Call your doctor for a new prescription. Throw away any unused medicine that is left over after injecting your dose.

Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.

If you use Gamunex at home, store it in the refrigerator and do not allow it to freeze. You may allow the medication to reach room temperature before measuring your dose in a syringe. Then place the vial back in the refrigerator.

What happens if I miss a dose?

Use Gamunex as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much Octagam.

What should I avoid while using Gamunex?

Do not receive live-virus vaccines such as measles, mumps, or rubella. The live vaccine may not work as well during this time, and may not fully protect you from disease.
