RIBASPHERE (ribavirin, USP) Capsules 200 mg

Hepatitis C is a viral infection of the liver. It’s often chronic, and can lead to cirrhosis and liver cancer. It’s difficult to treat, and harder to cure. Diagnosis is based on the antibodies your body produces in response to hepatitis C infection, liver biopsy, and/or a PCR test that directly measures the hep C viral activity in your blood. You can be a carrier, or have a persistent infection. When to treat and the best way to treat hepatitis C is not yet known.

Who should get tested for hepatitis C?

  • persons who ever injected illegal drugs, including those who injected once or a few times many years ago
  • persons who were treated for clotting problems with a blood product made before 1987 when more advanced methods for manufacturing the products were developed
  • persons who were notified that they received blood from a donor who later tested positive for hepatitis C
  • persons who received a blood transfusion or solid organ transplant before July 1992 when better testing of blood donors became available
  • long-term hemodialysis patients
  • persons who have signs or symptoms of liver disease (e.g., abnormal liver enzyme tests)
  • healthcare workers after exposures (e.g., needle sticks or splashes to the eye ) to HCV-positive blood on the job
  • children born to HCV-positive women
