Approved Drugs For Adults
There are currently 7 approved drugs in the United States for adults living with chronic hepatitis B infection. These include 5 types of antiviral drugs that are taken as a pill once a day for 1 year or longer. And there are 2 types of immune modulator drugs called interferon that are given as an injection for 6 months to 1 year.
It is important to know that not everyone needs to be treated. A liver specialist should evaluate your health through a physical exam, blood tests, and an imaging study of your liver . Then you can discuss together whether you are a good candidate for treatment since the approved drugs are most effective when there are signs of active liver disease. In addition, talk to your provider about HBV Clinical Trials since there are several new drugs being tested that are available for infected adults.
All adults, however, should be seen regularly by a liver specialist whether they are on treatment or not.
Preparation Prior To Transport
Label the specimen container with the patients full name, date of collection and one other unique identifier such as the patients date of birth or Health Card Number. Failure to provide this information may result in rejection or testing delay.
Centrifuge if using SST. Place specimen in biohazard bag and seal. Specimens should be stored at 2-8°C following collection.
Specimens more than the following number of days post collection will not be tested:
- > 6 days for Hepatitis B surface antigen
- > 7 days for Hepatitis B e Antigen and Hepatitis B e Antibody
- > 10 days for Hepatitis B core Antigen and Hepatitis B surface Antibody
Hepatitis B During Pregnancy
If a woman with HBV becomes pregnant, they may transmit the virus to their baby. Women should inform the doctor who delivers their baby that they have HBV.
The infant should receive an HBV vaccine and HBIG with 1224 hours of birth. This significantly reduces the risk that they will develop HBV.
The HBV vaccine is safe to receive while pregnant.
People with a high risk of HBV include:
- the infants of mothers with HBV
- the sexual partners of people with HBV
- people who engage in sexual intercourse without contraception and those who have multiple sexual partners
- men who have sex with men
- people who inject illicit drugs
- those who share a household with a person who has a chronic HBV infection
- healthcare and public safety workers who are at risk of occupational exposure to blood or contaminated bodily fluids
- people receiving hemodialysis, which is a type of kidney treatment
- people taking medications that suppress the immune system, such as chemotherapy for cancer
People can prevent HBV infection by:
- wearing appropriate protective equipment when working in healthcare settings or dealing with medical emergencies
- not sharing needles
- following safe sexual practices
- cleaning any blood spills or dried blood with gloved hands using a 1:10 dilution of one part household bleach to 10 parts water
A vaccine against HBV has been available since 1982.
People who should receive this vaccine include:

Hepatitis B Vs Hepatitis C
Hepatitis has many different types. HBV and the hepatitis C virus have both acute and chronic forms.
The main difference between HBV and HCV is how they spread from person to person. Although HCV is transmissible via sexual activity, this is rare. HCV usually spreads when blood that carries the virus comes into contact with blood that does not.
How Do I Repair Liver Damage Thats Been Done From Hepatitis C
The repair process comes in two forms how you move your body and what you put into it. Exercise is a great way to help your body to heal, as long as you find the balance between working your muscles safely and not overdoing it.
Many choose to begin walking and will increase the pace, distance, and time spent as their bodies become stronger. Others choose another form of exercise, such as swimming. If you are uncertain how to begin, many local gyms offer low cost or free trial memberships and have staff available to discuss how you can gain body strength without injuring yourself by trying to do too much too soon.
In addition to regular physical activity, liver repair requires healthy foods so that your body can heal. This is the time to focus your grocery shopping on the produce aisle. Here, youll find broccoli and spinach , tomatoes , asparagus and watermelon , and more. In the more middle aisles of the store, youll find healthy whole grains, such as brown rice and spices and seasonings, such as garlic and cayenne pepper .
By filling your cart and your body with these nutrients and drinking lots of water, youll be sending nutrients to your liver and helping to flush toxins out. You cannot magically fix your liver, but you can provide it with the nutrients it needs to heal and do your best not to further tax or stress it while your body works to heal the damage.

Symptoms Of Hepatitis C
Hepatitis C often doesnt have any noticeable symptoms until the liver has been significantly damaged. This means many people have the infection without realising it.
When symptoms do occur, they can be mistaken for another condition. Symptoms can include:
- flu-like symptoms, such as muscle aches and a high temperature
- feeling tired all the time
- loss of appetite

Origin Of Antiviral Resistance
The genetic makeup of viruses is constantly changing, which can cause a virus to become resistant to currently available treatments. Viruses can become resistant through spontaneous or intermittent mechanisms throughout the course of an antiviral treatment. Immunocompromised patients, more often than immunocompetent patients, hospitalized with are at the highest risk of developing oseltamivir resistance during treatment. Subsequent to exposure to someone else with the flu, those who received oseltamivir for “post-exposure prophylaxis” are also at higher risk of resistance.
Multiple strains of one virus can be present in the body at one time, and some of these strains may contain mutations that cause antiviral resistance. This effect, called the , results in immense variation in any given sample of virus, and gives the opportunity for natural selection to favor viral strains with the highest fitness every time the virus is spread to a new host. Also, recombination, the joining of two different viral variants, and , the swapping of viral gene segments among viruses in the same cell, play a role in resistance, especially in influenza.
Antiviral resistance has been reported in antivirals for herpes, HIV, hepatitis B and C, and influenza, but antiviral resistance is a possibility for all viruses. Mechanisms of antiviral resistance vary between virus types.

Hiv And Hbv Coinfection
About 2% of people with HIV in the United States are coinfected with HBV both infections have similar routes of transmission. People with HIV are at greater risk for complications and death from HBV infection. All people with HIV are recommended to be tested for HBV, and if susceptible, are further recommended to receive the hepatitis B vaccination or, if chronically infected, evaluated for treatment to prevent liver disease and liver cancer. For more information about HIV and HBV coinfection, visit HIV.govâs pages about hepatitis B and HIV coinfection.
Where Is The Hepatitis B Virus Found And How Is It Transmitted
Blood is the major source of the hepatitis B virus in the workplace. It can also be found in other tissues and body fluids, but in much lower concentrations. The risk of transmission varies according to the specific source. The virus can survive outside the body for at least 7 days and still be able to cause infection.

Treatments For Hepatitis B
Treatment for hepatitis B depends on how long you have been infected for.
If you have been exposed to the virus in the past few days, emergency treatment can help stop you becoming infected.
If you have only had the infection for a few weeks or months , you may only need treatment to relieve your symptoms while your body fights off the infection.
If you have had the infection for more than 6 months , you may be offered treatment with medicines that can keep the virus under control and reduce the risk of liver damage.
Chronic hepatitis B often requires long-term or lifelong treatment and regular monitoring to check for any further liver problems.

People With Chronic Hepatitis B
The vaccine does not affect people with chronic hepatitis B virus infection there are no therapeutic benefits or associated adverse events. The vaccine is also safe in people who are already immune to hepatitis B through past natural infection, but it offers no additional benefit.
Hepatitis B is an infection caused by hepatitis B virus. It affects the liver.

What Is Hepatitis B
Hepatitis B is an infection of your liver. Itâs caused by a virus. There is a vaccine that protects against it. For some people, hepatitis B is mild and lasts a short time. These âacuteâ cases donât always need treatment. But it can become chronic. If that happens, it can cause scarring of the organ, liver failure, and cancer, and it even can be life-threatening.
Itâs spread when people come in contact with the blood, open sores, or body fluids of someone who has the hepatitis B virus.
It’s serious, but if you get the disease as an adult, it shouldnât last a long time. Your body fights it off within a few months, and youâre immune for the rest of your life. That means you can’t get it again. But if you get it at birth, itâ unlikely to go away.
âHepatitisâ means inflammation of the liver. There are other types of hepatitis. Those caused by viruses also include hepatitis A and hepatitis C.
Hepatitis B Treatment: Medication
There are five FDA-approved oral medications and one injection available to treat hepatitis B. The newer oral medications are stronger and less likely to develop viral resistance and have very few side effects.
The medication cannot cure the disease, but can help reduce the number of viruses in the body and the risk of complications. You may undergo periodic blood tests to monitor drug resistance and determine whether the medication is having an effect.

Questions For Your Doctor
When you visit the doctor, you may want to ask questions to get the information you need to manage your hepatitis C. If you can, have a family member or friend take notes. You might ask:
What Do I Do If I Am Exposed To Hepatitis B
Contact your healthcare provider as soon as possible after the exposure. If you have not been vaccinated or are incompletely vaccinated, it may make sense for you to get a shot of hepatitis B immune globulin as soon as possible . HBIG provides short-term protection against the hepatitis B virus. When given shortly after an exposure , HBIG is 70-75% effective in preventing hepatitis B infection. Hepatitis B vaccination can be given at the same time, for long-term protection.

What Are The Symptoms Of Chronic Hepatitis B
About 1 in 20 people who get hepatitis B as adults become carriers, which means they have a chronic hepatitis B infection. Carriers are more likely to pass hepatitis B to other people. Most carriers are contagious meaning they can spread hepatitis B for the rest of their lives.
Hepatitis B infections that last a long time may lead to serious liver diseases like cirrhosis and liver cancer. About 1 in 5 people with chronic hepatitis B die from it. There are medicines that can help treat chronic hepatitis B infections.
Most babies who get hepatitis B develop chronic infection, unless they get treated right away. But treatments almost always work if your baby gets them quickly. Thats why its important for pregnant people to get tested for hepatitis B.
How Does One Administer Twinrix
Twinrix is given by injecting the liquid into the muscles. How many Twinrix shots do I need? It is provided as a sequence of three dosages. With the second dose given at least one month after the first. The final and third dose given at least six months after the first dosage.
A 4-dose rapid schedule is also accessible for individuals 19 years of age and over. It is safe to receive the hepatitis A and B vaccination in conjunction with other vaccines.

Whats The Procedure For A Hepatitis B Titer Test
A hepatitis titer test requires a healthcare professional to draw a small amount of blood for testing.
No special preparation is needed beforehand. If needles or the sight of blood make you anxious, you may want to arrange a drive ahead of time in case you feel faint.
Heres what will typically happen during this test:
Home tests that require a fingerpick are also available. The results of your tests are generally available within 3 days.
How Do People Get The Hbv Virus
Hepatitis B virus is found in the blood of people with HBV infection. It enters the body through blood-to-blood contact.
Reliable blood tests for HBV were developed many years ago. Since blood donors and blood products are tested for HBV, this is no longer the typical means of infection.
In many parts of the world, hepatitis B virus infects more than 8% of the population. HBV-infected women pass the infection to their babies during the birth process. People can also get hepatitis B by sharing needles for injection drug use, through sexual contact with an infected person, by an accidental needlestick with a contaminated needle, or from improperly sterilized medical, acupuncture, piercing, or tattooing equipment.

How Can I Prevent The Spread Of Hepatitis B Virus
The hepatitis B virus is spread by exposure to blood or body fluids from a person living with hepatitis B.
There are vaccines available to prevent HBV infection. The hepatitis B vaccine is provided free to babies as part of their routine childhood immunizations. For more information, see HealthLinkBC File #105 Diphtheria, Tetanus, Pertussis, Hepatitis B, Polio and Haemophilus influenzae type b Vaccine.
The vaccine is also provided free to those born in 1980 or later and to specific at-risk groups, such as sexual and household contacts of someone living with HBV and healthcare providers. For more information, see HealthLinkBC File #25a Hepatitis B Vaccine.
If you have been diagnosed with acute or chronic HBV infection, you can reduce the chance of passing this virus to others by doing the following:
Treatment For Suspected Exposure
Anyone who has had potential exposure to HBV can undergo a postexposure prophylaxis protocol.
This consists of HBV vaccination and hepatitis B immunoglobin . Healthcare workers give the prophylaxis after the exposure and before an acute infection develops.
This protocol will not cure an infection that has already developed. However, it decreases the rate of acute infection.

Side Effects Of Immunisation Against Hepatitis A
Immunisations against hepatitis A are effective and safe. All medications can have side effects.
For most people, the chance of a serious side effect from a vaccine is much lower than the chance of serious harm if you catch the disease.
Common side effects from the hepatitis A vaccine include:
- localised pain, redness and swelling at the injection site
- low-grade temperature
