Important Safety Information
Privigen is intravenous immune globulin therapy used to treat patients with primary immunodeficiency (PI), chronic inflammatory demyelinating polyneuropathy, or patients 15 years of age or older with chronic immune thrombocytopenic purpura. Since the medication is derived from human plasma, there’s always a risk of virus transmission, as well as Chreutzfeldt-Jakob disease (CJD) and its variant (vCJD).
Privigen is contraindicated in patients with a medical history of anaphylactic or severe systemic reaction to human immune globulin. Patients with hyperprolinemia, IgA-deficiencies, and/or a history of hypersensitivity should also avoid treatment with Privigen.
Talk with your doctor about your medical history, as well as all of the medications you’re currently taking — regardless of whether they are prescription, over-the-counter, vitamins, or herbal supplements. Certain medical conditions — especially in patients with renal dysfunction — may require treatment at the minimum dosage and infusion rate possible. Your doctor may also have to monitor for signs and symptoms of thrombosis and assess blood viscosity in patients who are at a higher risk for hyperviscosity.
There is unknown data about how Privigen would affect a fetus. Therefore, talk with your doctor if you’re pregnant, there’s a possibility you may be pregnant, or you’re planning on conceiving. Also, discuss if you’re currently breastfeeding.

Privigen may interfere with a person’s response to live virus vaccines and could lead to misinterpretation of serologic testing. You should talk to your doctor about Privigen alternatives if you’ve recently had a vaccine.

These include those of advanced age, a history of venous or arterial thrombosis, hypercoagulable conditions, prolonged immobilization, use of estrogens, indwelling vascular catheters, hyperviscosity, and cardiovascular risk factors.
