Uses Varicella, commonly known as chickenpox, is a highly contagious viral illness caused by the varicella-zoster virus (VZV). Most people who get VZV infection develop a rash and other symptoms that are usually self-limited and do not require treatment. However, VZV can cause severe complications in some people, such as pregnant women, immunocompromised individuals, and babies born to mothers who develop VZV infection during pregnancy. Varizig is indicated for the prevention of severe complications from VZV infection in people at risk, including those who are immunocompromised, pregnant women who are not immune to VZV, or newborns of mothers who develop VZV infection within 5 days before or 2 days after delivery. Dosage The dosage of Varizig depends on the age, weight, and clinical condition of the patient. The recommended dose for adults and children weighing more than 40 kg is 125 IU/kg of body weight, administered by intramuscular injection. For infants and children weighing less than 40 kg, the dose is based on body weight. The recommended dose is 625 IU for infants weighing less than 3 kg, 1250 IU for infants weighing 3-10 kg, and 2500 IU for children weighing more than 10 kg, administered by intramuscular injection. The recommended dose of Varizig for pregnant women is 625 IU, administered by intramuscular injection.

Faq for Varizig
Varizig is a medication used for post-exposure prophylaxis against varicella-zoster virus (VZV) infection. It is used to prevent or reduce the severity of chickenpox in individuals who have been exposed to the virus.
Varizig contains varicella-zoster immune globulin (VZIG), which is derived from human plasma. It works by providing passive immunity by temporarily increasing the levels of antibodies against VZV in the body. These antibodies help fight off the virus and prevent or reduce the severity of the infection.
Varizig should be administered as soon as possible after exposure to varicella-zoster virus, ideally within 96 hours (4 days) but can be given up to 10 days after exposure. The earlier it is given, the more effective it is.
Varizig is administered as an intramuscular injection. The recommended dosage and administration instructions may vary depending on the age and weight of the individual receiving the medication. It is typically given in a healthcare setting, such as a hospital or clinic, by a healthcare professional.
Like any medication, Varizig may cause side effects, although they are generally rare. Some possible side effects include pain or tenderness at the injection site, fever, headache, and rash. Serious allergic reactions are extremely rare but can occur. If you experience any unusual or severe side effects, you should seek medical attention immediately.
Varizig should not be administered to individuals who are allergic to human immunoglobulins or any other components of the medication. It is also not recommended for individuals with a history of anaphylactic or severe systemic reactions to human immunoglobulin products.
Varizig can be administered to pregnant women if the potential benefits outweigh the risks. While it is generally considered safe, it is essential to consult with a healthcare provider to evaluate the individual situation.
Varizig is effective in preventing or reducing the severity of chickenpox if administered within the recommended timeframe after exposure. However, it is not 100% guaranteed, and the effectiveness may vary depending on various factors, including the timing of administration and the individual's immune response. It is important to consult with a healthcare professional for accurate and updated information about Varizig and any medical treatment.
