What is Gamastan, and what is it used for?
Gamastan is a prescription immunoglobulin injection that provides rapid, short-term immunity against the hepatitis A virus in individuals at risk of exposure. It is also used to help prevent or reduce the severity of measles, varicella (chickenpox), and rubella (German measles) in people who have been recently exposed and lack prior immunization. The active components are antibodies sourced from human plasma. For hepatitis A prevention, it's given about two weeks before potential exposure. For measles or varicella exposure, it is administered within six days. Its use for rubella exposure is specific to pregnant women who are not immunized against the disease.

The most frequently reported side effects are local reactions at the injection site, such as pain, tenderness, and swelling. Systemic side effects can include fatigue, headache, fever, and nausea. As with any biological product, allergic reactions are possible and can range from mild to severe, including a life-threatening systemic reaction known as anaphylaxis, which involves a dangerous drop in blood pressure.
