Quick Answer

Chronic hepatitis B is treated with antiviral drugs such as tenofovir, entecavir, and peginterferon alfa-2a. These medications suppress the virus, reduce liver damage, and lower the risk of cirrhosis and liver cancer, but they rarely cure the infection. Treatment is long-term, often lifelong, and requires regular monitoring.

  • Tenofovir and entecavir are first-line oral antivirals for chronic hepatitis B.
  • Peginterferon alfa-2a is an injectable that may be used for a finite course.
  • Treatment aims to suppress viral replication, not to eliminate the virus completely.
  • Liver function and viral load are checked every 6-12 months during therapy.
  • If one drug fails, switching to another antiviral is a common strategy.
  • Hepatitis C is a different virus and is treated with direct-acting antivirals, not these drugs.

The Landscape

Hepatitis B is a viral infection that attacks the liver and can become chronic, meaning it lasts more than six months. Unlike hepatitis A, which is spread through contaminated food and water, hepatitis B spreads through blood and sexual contact. Chronic hepatitis B does not have a cure for most people, but antiviral medications can control the virus, preventing serious liver damage. The goal of treatment is to keep the virus at undetectable levels, reduce inflammation, and stop the progression to cirrhosis or liver cancer. Understanding the difference between hepatitis B and C is key, as they have different treatments and outcomes.

Treatment Windows by Infection

Bacterial infections clear with antibiotics measured in days: a single 500 mg intramuscular ceftriaxone dose for gonorrhea (doxycycline is added only if chlamydia has not been ruled out), seven days of doxycycline for chlamydia, penicillin injections for syphilis staged by duration. Viral infections play a longer game — suppressive antivirals for herpes, daily ART driving HIV to undetectable, and 8–12-week antiviral courses curing over 95% of hepatitis C cases.
