Warning

This medication may rarely cause serious blood clots (such as pulmonary embolism, stroke, heart attack, deep vein thrombosis). You may be at increased risk for blood clots if you are an older adult, are severely dehydrated, have a catheter in a vein close to your heart for administering medications, or have a history of blood clots, heart/blood vessel disease, heart failure, stroke, or if you are immobile (such as very long plane flights or bedridden). If you use estrogen-containing products, these may also increase your risk. Before using this medication, discuss the risks and benefits and if you have any of these conditions, report them to your doctor or pharmacist.

The risk of blood clots may be decreased by infusing this medication more slowly or by using a less concentrated form of this medication if available. Being adequately hydrated before receiving this medication may also help reduce this risk.

Get medical help right away if any of these side effects occur: shortness of breath/rapid breathing, chest/jaw/left arm pain, unusual sweating, sudden dizziness/fainting, pain/swelling/warmth in the arm/leg, sudden/severe headache, slurred speech, weakness on one side of the body, sudden vision changes, or confusion.

Uses

This medication is used to boost the body's natural defense system against infection in persons with a weakened immune system (primary immune deficiency). Immune globulin contains natural substances called antibodies (a type called IgG) that come from healthy human blood (plasma). These antibodies help protect your body against infections and help you to fight an infection if you get sick.

How to use

Read the Patient Information Leaflet provided by your pharmacist before you start using immune globulin and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

This medication is given slowly by injection under the skin (subcutaneous infusion) as directed by your doctor, usually once weekly. Some products may be given as often as every day up to once every 2 weeks. Follow your doctor's instructions carefully on how often to receive this medication. Dosage is based on your medical condition, weight, and response to treatment.

If you are giving this medication yourself, learn all preparation and usage instructions for the medication and infusion pump from your health care professional and the product directions. Do not inject this medication into a blood vessel. Learn how to store and discard needles and medical supplies safely. If any of the information is unclear, consult your health care professional.

Do not shake this medication. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Change the location of the injection site(s) with each dose to avoid problem areas under the skin. The recommended sites for injection are the abdomen, thighs, upper arms, and hips.

Patients who are getting immune globulin for the first time, those who are switched from another brand of immune globulin, or those who have not received immune globulin in the past 2 months may be at risk of developing fever, chills, nausea, vomiting, and rarely shock. It is recommended that these patients receive their first dose of this medication in the doctor's office/clinic so they can be monitored for these side effects.

Use this medication regularly to get the most benefit from it. To help you remember, mark your calendar with a reminder of which days you should receive the medication.

Side effects

See also Warning section.

Mild swelling, redness, or itching at the injection site may occur and usually lessen as your body adjusts to the medication. Headache, upset stomach, fever, nausea, diarrhea, sore throat, cough, or pain may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

  • severe headache
  • stiff neck

Though very unlikely to occur, this product may contain substances such as viruses that could cause infections because it is made from human blood (plasma). Careful screening of blood donors, special manufacturing methods, and tests are all used to reduce this risk. Discuss the benefits and risks of treatment with your doctor. Tell your doctor right away if you develop any signs of an infection such as:

  • persistent fever
  • persistent sore throat
  • unusual tiredness
  • yellowing eyes/skin
  • dark urine

Precautions

See also Warning section.

Before using this medication, tell your doctor or pharmacist if you are allergic to it; or to other immune globulin products; or if you have any other allergies. This product may contain inactive ingredients (such as polysorbate 80), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:

  • certain immune system problems (selective immunoglobulin A deficiency with known antibody against IgA, monoclonal gammopathy)
  • kidney disease
  • diabetes
  • current blood infection
  • severe loss of body fluids (dehydration)

Some immune globulin products are made with maltose. This substance can cause false high blood sugar levels when your blood sugar is normal or even low. If you have diabetes, check with your pharmacist whether the product you are using contains maltose and whether your blood sugar testing supplies will work with this product. Rarely, serious problems have occurred when too much insulin was given because of false high sugar readings or when low blood sugar went untreated.

Tell your doctor of any recent or planned immunizations/vaccinations. This medication may prevent a good response to certain live viral vaccines (such as measles, mumps, rubella, varicella). If you have recently received any of these vaccines, your doctor may have you tested for a response or have you vaccinated again later. If you plan on getting any of these vaccines, your doctor will instruct you about the best time to receive them so you get a good response.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.

Drug interactions

See also Warning section.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

This medication may interfere with certain tests (including certain blood sugar tests, blood type, Coombs test), possibly causing false test results. This can lead to serious (possibly fatal) consequences. Tell all lab personnel and all your doctors and pharmacists that you use this medication, and which type of blood sugar testing strips you use.

Overdose

If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center.
