Does hepatitis B go away on its own?

While most adults with acute hepatitis B are able to clear the infection on their own, it can also become chronic. Chronic hepatitis B isn’t curable, but it can be managed with treatment and lifestyle modifications.

Treatment for chronic hepatitis B may include antiviral medications.

Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) can help fight the virus and slow its ability to damage your liver.

As mentioned, acute hepatitis B infection will go away on its own.

Whether you are living with acute infection, or chronic infection, you can relieve your symptoms at home by resting, eating healthy foods, drinking plenty of water, and avoiding alcohol and drugs.

Your doctor will give you a treatment plan that is specific to your needs, as well as the dos and don’ts when it comes to medication and herbal products to avoid, because some can make liver damage caused by hepatitis B worse.

Who is at risk for hepatitis B?

According to the World Health Organization, hepatitis B rates have dropped from an average of 200,000 per year in the 1980s to around 20,000 new cases in 2016. In the United States, rates of new HBV infections are highest among adults aged 40-49 years, reflecting low hepatitis B vaccination coverage among adults at risk. The most common risk factor among people with new HBV infections is injecting drugs, related to the opioid crisis.

According to the U.S. Department of Health and Human Services (HHS), the following groups are most at risk of contracting hepatitis B:

  • People born in countries with an HBV prevalence of ≥2%
  • People born in the United States not vaccinated as infants whose parents were born in regions with high rates of HBV infections (HBsAg prevalence ≥8%)
  • Men who have sex with men
  • People who inject drugs
  • People with HIV
  • Household and sexual contacts of HBV-infected people
  • People requiring immunosuppressive therapy
  • People with end-stage renal disease (including hemodialysis patients)
  • Blood and tissue donors
  • People with elevated alanine aminotransferase levels (≥19 IU/L for women and ≥30 IU/L for men)
  • Pregnant women
  • Infants born to HBV-infected mothers
