Lyophilized human immunoglobulin for intravenous injection (pH4)

This product contains broad-spectrum IgG antibodies against viruses, bacteria or other pathogens. In addition, the unique type of immunoglobulin and unique type antibodies can form a complex immune network, so it has the dual therapeutic effects of immune replacement and immune regulation. After intravenous infusion, it can quickly increase the IgG level in the recipient's blood and enhance the body's anti-infection ability and immune regulation function.

Main components: More than 95% of the protein in this product is human immunoglobulin.

1. Primary immunoglobulin deficiency such as X-linked hypoimmunoglobulinemia, common variable immunodeficiency, immunoglobulin G subtype deficiency, etc. 2. Secondary immunoglobulin deficiency such as severe infection, neonatal sepsis, etc. 3. Autoimmune diseases such as idiopathic thrombocytopenic purpura, Kawasaki disease.

Usage: Dissolve the product with sterile water for injection until the IgG content is 5% and drip it intravenously or dilute it with 5% glucose solution 1 to 2 times for intravenous drip. The initial drip rate is 1.0 ml/min (about 20 drops/min). After 15 minutes, if there is no adverse reaction, the rate can be gradually increased. The fastest drip rate should not exceed 3.0 ml/min (about 60 drops/min). Dosage: Follow the doctor's advice. Recommended dose: 1. Idiopathic immunoglobulin deficiency or hypoimmunoglobulinemia: initial dose: 400 mg/kg body weight; maintenance dose: 200-400 mg/kg body weight. The dosing interval depends on the patient's serum IgG level and condition, usually once a month. 2. Idiopathic thrombocytopenic purpura: 400 mg/kg body weight per day for 5 consecutive days. The maintenance dose is 400 mg/kg body weight each time. The interval depends on the platelet count and condition, usually once a week. 3. Symptomatic infection: 200-300 mg/kg body weight per day for 2-3 consecutive days. 4. Scurvy: Apply within 10 days of onset. The pediatric therapeutic dose is 2.0 g/kg body weight for one infusion

Generally, there are no adverse reactions. Very few patients may experience transient headaches, palpitations, nausea and other adverse reactions during infusion, which may be related to the rapid infusion speed or individual differences. Most of the above reactions are mild and often occur within one hour after the start of infusion. Therefore, it is recommended to regularly observe the patient's general condition and vital signs during the entire infusion process, slow down or pause the infusion if necessary, and generally recover on their own without special treatment. Some patients may experience the above reactions after the end of the infusion, and generally recover on their own within 24 hours.
