How is this IVIG supposed to help with the low blood pressure? I googled IVIG and wikipedia says it's some sort of blood transfusion used for Immune deficiencies such as X-linked agammaglobulinemia, hypogammaglobulinemia (primary immune deficiencies), and acquired compromised immunity conditions (secondary immune deficiencies) featuring low antibody levels.Autoimmune diseases, e.g. immune thrombocytopenia, and inflammatory diseases, e.g. Kawasaki disease.Acute infections.IVIG is given as a plasma protein replacement therapy (IgG) for immune deficient patients who have decreased or abolished antibody production capabilities. In these immune deficient patients, IVIG is administered to maintain adequate antibody levels to prevent infections and confers a passive immunity. Treatment is given every 3–4 weeks. In the case of patients with autoimmune disease, IVIG is administered at a high dose (generally 1-2 grams IVIG per kg body weight) to attempt to decrease the severity of the autoimmune diseases such as dermatomyositis. Currently, IVIg is being increasingly used off-label in a number of pathological conditions; the increasing world-wide usage of IVIg may lead to shortages of this beneficial drug. IVIG is useful in some acute infection cases such as pediatric HIV infection as well as autoimmune, such as Guillain–Barré syndrome.[1] I didn't read anything about it for pots :/ Sorry this is way over my head.
