Introduction About ENGERIX B ADULT 20MCG INJECTION
ENGERIX B ADULT 20MCG 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, ENGERIX B ADULT 20MCG 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.
ENGERIX B ADULT 20MCG INJECTION should be administered only in the muscles or beneath the skin by a trained health care professional. Do not receive ENGERIX B ADULT 20MCG INJECTION if you are allergic to hepatitis B antigen or have major illness with high fever. Before receiving ENGERIX B ADULT 20MCG INJECTION, inform your doctor if you are pregnant or breastfeeding as a precaution.
ENGERIX B ADULT 20MCG 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.
Uses Of ENGERIX B ADULT 20MCG INJECTION
- Immunization against Hepatitis B Infection
How ENGERIX B ADULT 20MCG INJECTION Works
The hepatitis B vaccine works by introducing a small, harmless piece of the hepatitis B virus, usually a surface protein, into the body. This protein doesn’t cause the disease, but it triggers the immune system to recognize it as a threat. The immune system then creates antibodies against the protein. If you are later exposed to the actual hepatitis B virus, your immune system recognizes it quickly and fights it off, preventing the infection from taking hold.
