Immune globulin (intravenous and subcutaneous)

Immune globulin (intravenous and subcutaneous) is used to treat primary immunodeficiency.

Immune globulin is also used to raise platelet levels in people with idiopathic thrombocytopenic purpura.

Immune globulin is also used to treat certain serious nerve disorders that cause muscle weakness and may impact daily activities.

Immune globulin may also be used for reasons not mentioned in this medication guide.

Immune globulin can cause blood clots. The risk is highest for older adults or for people who have had blood clots, heart problems, or blood circulation problems. Blood clots are also more likely during long-term bedrest, while using birth control pills or hormone replacement therapy, or while having a central intravenous (IV) catheter in place.

Call your doctor immediately if you have chest pain, trouble breathing, fast heartbeats, numbness or weakness, or swelling and warmth or discoloration in an arm or leg.

This medicine can also harm your kidneys, especially if you have kidney disease or if you are using certain other medicines. Tell your doctor right away if you notice signs of kidney problems, such as swelling, rapid weight gain, and little or no urination.

You should not use this medicine if:

• you have had an allergic reaction to an immune globulin or blood product; or
• you have immune globulin A (IgA) deficiency with antibody to IgA.

Immune globulin can cause blood clots or kidney problems, especially in older adults or in people with certain conditions. Tell your doctor if you have ever had:

• heart problems, blood circulation problems, or "thick blood";
• a stroke or blood clot;
• kidney disease;
• diabetes;
• an infection called sepsis;
• if you use estrogens (birth control pills or hormone replacement therapy);
• if you have been on long-term bedrest; or
• if you have a central intravenous (IV) catheter in place.

You may need a dose adjustment if you are exposed to measles, or if you travel to an area where this disease is common.

Tell your doctor if you are pregnant or breastfeeding.

Immune globulin is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.

Get emergency medical help if you notice signs of an allergic reaction: hives; wheezing, trouble breathing; dizziness, feeling like you might faint; swelling of your face, lips, tongue, or throat.

Some side effects may happen during the injection. Let your caregiver know if you feel light-headed, itchy, cold, sweaty, or if you experience chest discomfort, fast heartbeats, severe headache, or a pounding feeling in your neck or ears.

Immune globulin may lead to serious side effects. Contact your doctor immediately if you have:

• a blood cell disorder--pale or yellow skin, dark urine, fever, confusion, or weakness;
• dehydration symptoms--extreme thirst or heat, inability to urinate, heavy sweating, or hot and dry skin;
• kidney issues--little to no urination, swelling, rapid weight gain, feeling short of breath;
• lung issues--chest pain, wheezing, difficulty breathing, blue lips, fingers, or toes;
• signs of a new infection--fever with severe headache, neck stiffness, eye pain, and increased sensitivity to light; or
• signs of a blood clot--shortness of breath, chest pain with deep breathing, rapid heart rate, numbness or weakness on one side of the body, swelling and warmth or discoloration in an arm or leg.

Common side effects of immune globulin may include:

• runny or stuffy nose, sinus pain, cough, sore throat;
• fever, chills, weakness;
• headache, back pain, muscle or joint pain;
• dizziness, tiredness, feeling down;
• swelling in your hands or feet;
• skin rash, redness, or bruising;
• blisters or sores in your mouth, red or swollen gums, trouble swallowing;
• nausea, diarrhea, stomach pain, upset stomach;
• increased blood pressure; or
• redness, swelling, or itching at the injection site.

This is not a complete list of side effects, and others may happen. Contact your doctor for medical advice about side effects. You can report side effects to the FDA at 1-800-FDA-1088.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Immune globulin is given as an infusion into a vein, or injected under the skin using an infusion pump. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Do not inject immune globulin into a vein if you have been instructed to give the medicine as a subcutaneous injection (under the skin).

How you give this medication, how often you use it, and the length of your infusion time will depend on the condition being treated.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.

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

Do not shake the medication bottle or you may ruin the medicine.

Immune globulin must be given slowly. You may need to use several catheters to inject immune globulin into different body areas at the same time. Your healthcare provider will show you the best places on your body to inject the medication. Keep a diary of the days and times you gave the injection and where you injected it on your body.

Drink plenty of liquids while you are using this medicine to help improve your blood flow and keep your kidneys working properly.

You may need frequent blood or urine tests.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using immune globulin.

Store this medicine in its original carton in the refrigerator. Do not freeze immune globulin, and throw the medicine away if it has frozen.

Take the medicine out of the refrigerator and let it reach room temperature for up to 1 hour before injecting your dose.

You may also store immune globulin at room temperature.

You will need to use immune globulin within a certain number months. This will depend on the how you store the medicine (at room temperature, or in a refrigerator). Carefully follow the storage instructions provided with your medicine. Do not use the medicine after the expiration date on the label has passed.

Each vial (bottle) is for one use only. Throw it away after one use, even if there is still medicine left inside.

Use disposable injection items (needle, catheter, tubing) only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

Call your doctor for instructions if you forget to take a dose.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Do not get a "live" vaccine while using immune globulin. The vaccine may not work as well and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), and nasal flu (influenza) vaccine.

Immune globulin can damage your kidneys, particularly if you are also taking certain medicines for infections, cancer, osteoporosis, organ transplant rejection, bowel disorders, high blood pressure, or pain or arthritis (including Advil, Motrin, and Aleve).

Other medications may interact with immune globulin, including both prescription and over-the-counter medicines, vitamins, and herbal products. Inform your doctor about all the medicines you are currently taking and any new medicines you begin or stop using.
