Patient Education: Hepatitis B

What is hepatitis B?

Hepatitis B is a liver disease.

Hepatitis (HEP-ah-TY-tis) makes your liver swell and stops it from working right.

You need a healthy liver. The liver does many things to keep you alive. The liver fights infections and stops bleeding. It removes drugs and other poisons from your blood. The liver also stores energy for when you need it.

What causes hepatitis B?

Hepatitis B is caused by a virus.

A virus is a germ that causes sickness. (For example, the flu is caused by a virus.) People can pass viruses to each other. The virus that causes hepatitis B is called the hepatitis B virus.

How could I get hepatitis B?

Hepatitis B spreads by contact with an infected person's blood, semen, or other body fluid.

Hepatits B symptoms

A biopsy (BYE-op-see) is a simple test. The doctor removes a tiny piece of your liver through a needle. The doctor checks the piece of liver for signs of hepatitis B and liver damage.

How is hepatitis B treated?

Treatment for hepatitis B may involve:

  • Hepatitis B is treated through shots of medicine.
  • A drug called Interferon (in-ter-FEAR-on). It is given through shots. Most people are treated for 4 months.
  • A drug called Lamivudine (la-MIV-you-deen). You take it by mouth once a day. Treatment is usually for one year.
  • A drug called Adefovir Dipivoxil (uh-DEH-foh-veer dih-pih-VOX-ill). You take it by mouth once a day. Treatment is usually for one year.
  • Surgery. Over time, hepatitis B may cause your liver to stop working. If that happens, you will need a new liver. The surgery is called a liver transplant. I t involves taking out the old, damaged liver and putting in a new, healthy one from a donor.
  • A drug called Entecavir (en te' ka veer). Entecavir is used to treat chronic (long-term) hepatitis B infection in people who have liver damage. Entecavir is in a class of medications called nucleoside analogs. It works by decreasing the amount of hepatitis B virus (HBV) in the body.Entecavir comes as a tablet and solution (liquid) to take by mouth.
  • A drug called Tenofovir (te noe' fo veer). Tenofovir, also called tenofovir disoproxil fumarate, is an antiviral drug for treating chronic hepatitis B. It's sold under the brand name Viread by Gilead Sciences, Inc. Tenofovir is also used to treat HIV infection. Viread is a 300 mg tablet. For chronic hepatitis B, the usual dosing for adults is 300 mg once a day and can be taken with or without food.

How can I protect myself?

You can get the hepatitis B vaccine.

A vaccine is a drug that you take when you are healthy that keeps you from getting sick. Vaccines teach your body to attack certain viruses, like the hepatitis B virus.

The hepatitis B vaccine is given through three shots. All babies should get the vaccine. Infants get the first shot within 12 hours after birth. They get the second shot at age 1 to 2 months and the third shot between ages 6 and 18 months.

Older children and adults can get the vaccine, too. They get three shots over 6 months. Children who have not had the vaccine should get it.

You need all of the shots to be protected. If you are traveling to other countries, make sure you get all the shots before you go. If you miss a shot, call your doctor or clinic right away to set up a new appointment.

Vaccines protect you from getting hepatitis B.

People who touch blood at work should wear gloves to protect themselves from hepatitis B.

You can also protect yourself and others from hepatitis B if you:

  • use a condom when you have sex
  • don't share drug needles with anyone
  • wear gloves if you have to touch anyone's blood
  • don't use an infected person's toothbrush, razor, or anything else that could have blood on it
  • make sure any tattooing or body piercing is done with clean tools
