What is sofosbuvir?
Sofosbuvir is an antiviral medication that prevents hepatitis C virus (HCV) from multiplying in your body.
Sofosbuvir is used in combination with other medications to treat hepatitis C in adults. Sofosbuvir is sometimes used in people who also have HIV, or people who have liver cancer and are going to have a liver transplant. Sofosbuvir is not a treatment for HIV or AIDS.
Sofosbuvir must be given in combination with other antiviral medications and should not be used alone. Sofosbuvir is usually given with ribavirin (Copegus, Rebetol, Ribasphere, RibaTab) with or without peginterferon alfa (Pegasys, PegIntron).
Sofosbuvir may also be used for purposes not listed in this medication guide.
What is the most important information I should know about sofosbuvir?
Sofosbuvir is used in combination with other medications, usually ribavirin with or without peginterferon alfa.
Read the medication guide or patient instructions provided with each medication in your combination therapy. Do not change your doses or medication schedule without your doctor's advice.
Ribavirin can cause birth defects or death in an unborn baby. Do not use sofosbuvir with ribavirin if you are pregnant, or if you are a man and your female sexual partner is pregnant. Use at least 2 effective forms of non-hormonal birth control while using these medicines together and for at least 6 months after treatment ends.
What should I discuss with my healthcare provider before taking sofosbuvir?

Sofosbuvir is used in combination with ribavirin. Ribavirin can cause birth defects or death in an unborn baby. You may need to have a negative pregnancy test before using these medications together, and every month during your treatment.
If you are a woman, do not use sofosbuvir with ribavirin if you are pregnant.
If you are a man, do not use this drug combination if your sexual partner is pregnant. An unborn baby could also be harmed if a man fathers the child while he is taking ribavirin.

Keep using 2 forms of birth control for at least 6 months after treatment ends.
