Drug information
What is sofosbuvir?
Sofosbuvir is an antiviral prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic hepatitis C virusinfection (HCV) in adults and children 3 years of age and older who meet specific requirements, as determined by a health care provider.
HCV infection is an opportunistic infection (OI) of HIV. An OI is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as people with HIV—than in people with healthy immune systems. To learn more about OIs, read the HIVinfo What is an Opportunistic Infection? fact sheet.
To learn how HIV and HCV are connected, read the HIVinfo HIV and Hepatitis C fact sheet. The fact sheet includes information about how HCV is spread, symptoms of HCV, and treatment options.
How is sofosbuvir used in people with HIV?
The Guidelines for the Prevention and Treatment of Opportunistic Infections in Adults and Adolescents with HIV reference the AASLD-IDSA HCV Guidance: Recommendations for Testing, Managing, and Treating Hepatitis C, which includes recommendations on the use of sofosbuvir to treat HCV infection in people with HIV.
The recommended uses may not always be consistent with FDA-approved uses of sofosbuvir. See the guidelines for complete information on recommended uses of sofosbuvir in adults and children with HIV. Some recommended uses, such as uses in certain rare circumstances, may have been omitted above.
What should I tell my health care provider before taking sofosbuvir?
Before taking sofosbuvir, tell your health care provider:
- If you are allergic to sofosbuvir or any other medicines.
- About any medical conditions you have or have had, for example, kidney or liver problems.
- About anything that could affect your ability to take medicines, such as difficulty swallowing or remembering to take pills.
- If you are pregnant or plan to become pregnant. Sofosbuvir, in combination with ribavirin or with peginterferon alfa and ribavirin, may cause birth defects or death of an unborn child. Pregnant women and men whose partners are pregnant should not use these medicines. Women should not become pregnant during treatment with sofosbuvir plus ribavirin or with sofosbuvir plus peginterferon alfa and ribavirin. Two forms of effective birth control should be used to avoid pregnancy. Women should also not become pregnant for 6 months after they stop taking these medicines or for 6 months after their male partners stop taking these medicines. Talk to your health care provider about possible risks with taking sofosbuvir during pregnancy.
- If you are breastfeeding or plan to breastfeed. Do not breastfeed if you have HIV.
- About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Sofosbuvir may affect the way other medicines or products work, and other medicines or products may affect how sofosbuvir works. Ask your health care provider if there are interactions between sofosbuvir and the other medicines you take.
How should I take sofosbuvir?
Take sofosbuvir according to your health care provider’s instructions. Your health care provider will tell you how much sofosbuvir to take and when to take it. Before you start sofosbuvir and each time you get a refill, read any printed information that comes with your medicine.
How should sofosbuvir be stored?
