Hepatitis B (HBV) is a viral infection that attacks the liver. Some people clear it quickly; others develop chronic infection that needs long-term care. You can get infected through blood, sex, or from mother to baby at birth. If you think you were exposed or have symptoms, testing is the first step.
Early signs can be subtle: fatigue, mild fever, stomach pain, dark urine, or jaundice (yellow skin/eyes). Many people have no symptoms at all. A simple blood panel checks for HBsAg, anti-HBs, and HBV DNA — these tell whether you have an active infection, immunity, or need follow-up. If tests show chronic HBV, your doctor will usually order liver enzymes (ALT/AST) and imaging like ultrasound or FibroScan to check liver health.
Not everyone with HBV needs antiviral drugs right away. When treatment is needed, the most common, effective medicines are tenofovir and entecavir. These drugs suppress the virus and lower the chance of liver damage. There’s also a very effective vaccine that prevents infection — it’s the best protection for uninfected people. Pregnant people with HBV can take steps at delivery to lower baby transmission; talk with your provider early.
Living with HBV means regular monitoring. You’ll get periodic blood tests and imaging to spot liver inflammation, scarring, or early signs of liver cancer. Avoid heavy alcohol, which speeds liver damage. Get vaccinated household members and practice safer sex to protect others.
Watch your medicines. Some drugs and supplements can hurt the liver. A key example: acetaminophen (Tylenol) is safe at recommended doses but can be dangerous if you take too much. Read our Tylenol guide for liver-safe tips and dosing reminders.
If you’re using online pharmacies or ordering antivirals, be cautious. We have guides on buying antiviral meds and safe online pharmacies — use them to check legitimacy, confirm prescriptions, and avoid counterfeit drugs. For specific antiviral info, see our article on buying Famvir online; for general online pharmacy safety, check our BlueSkyDrugs and buying guides.
When to see a doctor now: if you have jaundice, severe abdominal pain, confusion, or vomiting, seek urgent care. For routine care, set up regular follow-ups so your provider can track liver health and adjust treatment. With the right monitoring and choices, many people with HBV live full, healthy lives.
