What should you know about HIV and hepatitis B coinfection treatment?

HIV affects immune cells, while hepatitis B can persist in the liver and cause inflammation. Some antiviral medicines act against both viruses, so clinicians select a complete HIV regimen that also provides appropriate hepatitis B activity. Stopping a medicine that suppresses hepatitis B without medical guidance can allow liver inflammation to flare.

The plan depends on viral tests, liver assessment, kidney function, previous medicines, pregnancy possibility, and other health conditions. Follow-up may include blood tests, medication reviews, and discussion of adherence, side effects, and interactions.

Take medicines exactly as prescribed and tell the treating team before starting, stopping, or changing any prescription, supplement, or recreational drug. Keep appointments for HIV monitoring and liver function tests, even when you feel well. Store medicines safely and discuss missed doses rather than doubling up without advice.

Ask about protecting household and sexual contacts from hepatitis B, including testing and vaccination where appropriate. Avoid sharing razors or toothbrushes, and use barrier protection until your clinician explains your individual prevention plan.

Seek urgent care for yellow skin or eyes, very dark urine, severe abdominal swelling or pain, repeated vomiting, unusual sleepiness, confusion, or rapidly worsening weakness. Report a new rash, facial swelling, breathing difficulty, or severe medicine reaction immediately. Contact your treatment team promptly if you cannot take medicines or have stopped them.

Ask which medicines treat both infections, how liver function will be monitored, what to do after a missed dose, and which interactions matter. Discuss hepatitis B vaccination for close contacts, symptoms such as fatigue or dark urine, and how specialist follow-up will be coordinated.
