Simeprevir, sold under the trade names Olysio among others, is a medication used in combination with other medications for the treatment of hepatitis C. It is specifically used for hepatitis C genotype 1 and 4. Medications it is used with include sofosbuvir or ribavirin and peginterferon-alfa. Cure rates are in 80s to 90s percent. It may be used in those who also have HIV/AIDS. It is taken by mouth once daily for typically 12 weeks.

Common side effects include feeling tired, headache, rash, itchiness, and sensitivity to sunlight. In those with previous hepatitis B infection, active disease may recur. It is not recommended in those with significant liver problems. During pregnancy when used with ribavirin it may cause harm to the baby while when used with sofosbuvir its safety is unclear. Simeprevir is a HCV protease inhibitor.

Simeprevir was as developed by Medivir AB and Janssen Pharmaceutica. It was approved for medical use in the United States in 2013. Simeprevir is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. It is not available as a generic medication as of 2015. In the United Kingdom a course of treatment with ribavirin and peginterferon-alfa cost about 29,700 pounds in 2015. In the United States a course of treatment with sofosbuvir was more than 171,000 USD in 2015 with the simeprevir component costing 66,360 USD.

Simeprevir is indicated treating chronic hepatic C (CHC) infection as a part of a triple antiviral treatment regimen consisting of two other drugs: peginterferon-alfa (PEG-IFN) and ribavirin (RBV). It is primarily effective in treating Hepatitis C virus (HCV) genotype 1 infected subjects with compensated liver disease, including cirrhosis. There are currently no studies that show Simeprevir’s effectiveness as a single therapy for HCV. Simeprevir is generally used for HCV genotype 1 infected subjects, but off-label medical use has been indicated for type 4 genotype as well.
