Treatment for acute hepatitis B

Supportive care includes adequate fluids, food as tolerated, rest guided by energy levels and avoidance of alcohol or unnecessary products that may strain the liver. Antiviral medicine is not routinely required for every uncomplicated acute infection, but specialists may use it when disease is severe or prolonged.

The plan depends on symptoms, liver blood tests, clotting function, viral markers and the person's wider health. Follow-up checks whether inflammation is settling and whether the surface antigen clears. Ongoing infection needs a different assessment from a recent acute episode.

Hospital care may include intravenous fluids, control of nausea and close observation for changes in alertness, bleeding or liver function. A liver specialist directs antiviral treatment and advanced care when there are signs of severe liver failure.

Keep scheduled blood tests and clinical reviews even when you feel better. Drink regularly and use small meals if nausea limits eating. Check every prescription, pain reliever, supplement and herbal preparation with a clinician or pharmacist, because an inflamed liver may process products differently.

Prevent blood and sexual exposure while infection status is being followed: cover cuts, do not share razors, toothbrushes or injection equipment, and use barrier protection. Household and sexual contacts should ask promptly about testing and vaccination. Do not donate blood.

Go to emergency care for confusion, unusual sleepiness, collapse, vomiting blood, black stools, severe bleeding or difficulty waking. These features can indicate failing liver function and require hospital assessment.

Contact a clinician urgently if repeated vomiting prevents hydration, abdominal pain is intense, urine output drops, or yellowing rapidly deepens. Pregnancy, immune suppression and established liver disease warrant early specialist input because monitoring and treatment decisions may differ.

Ask how often liver and viral tests need checking, which warning signs should send you to hospital, and which medicines are safe. Clarify how recovery will be confirmed, whether specialist review is needed and how contacts can access vaccination.
