immune globulin (human) (IgG) SubQ 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 immune globulin (human) (IgG) SubQ
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), usually once a week or as directed by your doctor. Do not inject this medication into a blood vessel. Dosage is based on your medical condition, weight, and response to therapy.
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.
Do not shake the vials. 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 each week 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, use it at the same time each week. It may help to mark your calendar with a reminder.
immune globulin (human) (IgG) SubQ Side Effects
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.
Tell your doctor right away if you have any serious side effects, including: change in the amount of urine, sudden weight gain, fast heartbeat.

You may be at increased risk for blood clots if you are severely dehydrated, 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, if you have any of these conditions report them to your doctor or pharmacist.

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).
