This medication is used to prevent a certain serious virus infection (hepatitis B) in people who have been exposed to this virus under certain conditions (such as direct contact with blood or body fluids containing this virus). Certain brands of this medication may also be given after a liver transplant to prevent return of hepatitis B infection in people with previous infection. Ask your doctor or pharmacist if you have questions about your particular brand. This medication is made from healthy human blood that has high levels of certain defensive substances (antibodies) that help fight hepatitis B.
How to use Hepagam B Vial
If this medication is given for prevention of hepatitis B after direct exposure to the virus, it is given by injection into a muscle by a healthcare professional. It is best to receive this medication as soon as possible after exposure. If you wait too long after being exposed, the medication may not be effective. Your doctor may also recommend vaccination after receiving this medication. Talk with your doctor about the best treatment for you.
If this medication is given after a liver transplant to prevent return of hepatitis B infection, it is given by injection into a vein by a healthcare professional. For this use, it should be given on a regular schedule. To help you remember, mark your calendar with an appointment reminder.
The dosage and schedule of injections is based on your medical condition, weight, and response to treatment.

This medication may rarely cause serious blood clots (such as pulmonary embolism, stroke, heart attack, deep vein thrombosis). You may be at increased risk for blood clots if you are an older adult, are severely dehydrated, have a catheter in a vein close to your heart for administering medications, or have a history of blood clots, heart/blood vessel disease, heart failure, stroke, or if you are immobile (such as very long plane flights or bedridden).

Before using this medication, discuss the risks and benefits and if you have any of these conditions, report them to your doctor or pharmacist.
Being adequately hydrated before and after receiving this medication may help reduce your risk of blood clots. If you are receiving this medication into a vein, the risk may also be decreased by infusing this medication more slowly or by using a less concentrated form of this medication if available.
