Protease Inhibitors (PIs) for Hepatitis C
How It Works
Protease inhibitors (PIs) are antiretroviral medicines. They prevent the hepatitis C virus from multiplying.
Why It Is Used
Combination antiviral therapy with boceprevir or telaprevir is used to treat people who have ongoing (chronic) hepatitis C infection.
How Well It Works

What To Think About
People with normal or slightly elevated liver enzyme levels but whose liver biopsy shows little or no liver damage may choose not to have antiviral treatment. Instead, a doctor can monitor the condition with periodic liver function tests and a liver biopsy every 3 to 5 years.
Even if the initial treatment does not eliminate the virus, your doctor may advise you to continue antiviral treatment, because it may reduce liver inflammation. For some people with significant liver damage, antiviral therapy may slow the progression of liver damage or make liver cancer less likely.5 If you already have cirrhosis, some studies show that antiviral therapy can help you live longer.6
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
