What should you know about hepatitis C rash?

Skin changes can occur for many reasons, including irritation, allergy, infection, medicines, or an immune-related problem. Hepatitis C may be associated with skin symptoms in some people, but a rash is not a reliable way to identify the infection. Most people with hepatitis C do not have a rash as their only clue. A clinician will consider its appearance, location, timing, itching, other symptoms, and any new products or medicines.

Arrange a GP Consultation if the rash is persistent, spreading, painful, or unexplained. Take a clear photograph if it changes before the appointment, and list recent medicines, supplements, soaps, and foods. If hepatitis C is a concern, testing can clarify exposure and current infection. Your clinician may also request a Liver Function Test; this does not identify the rash by itself, but can contribute to the wider assessment.

Get emergency help for a rash with breathing difficulty, swelling of the lips or tongue, faintness, blistering, skin peeling, or sores in the mouth or eyes. Seek prompt medical review for a rash with fever, rapidly worsening yellow skin or eyes, dark urine, unusual bleeding, or severe weakness. These features can signal a serious allergic, infectious, or liver-related problem.

Ask what the rash could represent, whether any medicine or product may have triggered it, whether hepatitis testing is appropriate, which warning signs matter, and what skin care is safe while waiting.
