GENEVAC B INJECTION is used to offer protection against hepatitis B infection. It contains Hepatitis B Antigen which belongs to the group of medicines called Vaccines. Upon vaccination, GENEVAC B INJECTION releases a harmless version of hepatitis B virus to which our body produces antibodies. As these hepatitis B viruses are in harmless form, our body easily destroys them and stores it as memory. Upon future exposure to active hepatitis B infection, our body releases antibodies and kills the active virus. GENEVAC B INJECTION should be administered only in the muscles or beneath the skin by a trained health care professional. Do not receive GENEVAC B INJECTION if you are allergic to hepatitis B antigen or have major illness with high fever. Before receiving GENEVAC B INJECTION, inform your doctor if you are pregnant or breastfeeding as a precaution. GENEVAC B INJECTION is generally well-tolerated. However, it may cause pain at injection site, tiredness and fatigue in some individuals which usually resolves on its own in 1-2 days. Consult your doctor if they trouble you.
