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.

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.
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 or every 2 weeks. Do not inject this medication into a blood vessel. 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. Learn how to store and discard needles and medical supplies safely. If any of the information is unclear, consult your health care professional.

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.
