Histoglob Injection 1ml is a sterile injectable formulation containing Human Normal Immunoglobulin (12mg), Histamine Dihydrochloride (0.15mcg), and Sodium Thiosulphate (32mg). This combination is designed to provide passive immunity by supplying a broad spectrum of antibodies derived from pooled human plasma, thereby enhancing the recipient’s immune response against a variety of pathogens. The inclusion of Histamine Dihydrochloride acts as an immunomodulator, facilitating improved antigen presentation and activation of immune effector cells, while Sodium Thiosulphate serves as an antioxidant, helping to mitigate oxidative stress and improve cellular protection. Histoglob Injection is indicated for use in immunodeficiency states, prophylaxis against certain infections, and as an adjunct in immunotherapy protocols. It is administered intramuscularly or intravenously under strict aseptic conditions, with dosage and frequency determined by the clinical condition and physician’s discretion. Caution is advised in patients with known hypersensitivity to immunoglobulins or any component of the formulation. Adverse reactions may include mild local pain, erythema, or systemic hypersensitivity responses. Histoglob Injection should be stored according to manufacturer recommendations to maintain potency and sterility. Proper patient monitoring during administration is essential to ensure safety and therapeutic efficacy.
