How does Sovaldi work? What will it do for me?

Sofosbuvir belongs to the class of medications called antivirals. It is used to treat chronic infection with hepatitis C virus. Sofosbuvir is used along with ribavirin and sometimes peginterferon alfa.

Sofosbuvir works by blocking one of the steps in the reproduction of the virus, helping to stop the duplication of the virus and allowing the body to get rid of the virus. It must be used in combination with other antiviral medications to reduce the opportunity for the virus to become resistant to it.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

What form(s) does Sovaldi come in?

Each yellow, capsule-shaped, film-coated, tablet debossed with "GSI" on one side and "7977" on the other side contains 400 mg of sofosbuvir.

How should I use Sovaldi?

The recommended adult dose of sofosbuvir is 400 mg (1 tablet) taken once daily. It must be taken with another antiviral medication. Your doctor will determine which other antiviral medication is most appropriate for treating you, depending on characteristics of the hepatitis C virus. If these medications must be stopped, sofosbuvir must also be stopped.

Sofosbuvir may be taken for 12 weeks to 24 weeks, depending on the other antiviral medications you are taking and your body’s response to the medication.

Sofosbuvir may be taken with or without food.

These factors may affect how you should use this medication.

Heart function: Taking sofosbuvir while taking certain medications to control heart rhythm may result in a serious decrease in the heart rate.

Hepatitis B reactivation: People who have hepatitis B infection that is dormant may experience the infection returning, causing further liver dysfunction or liver failure.

Two forms of effective birth control (one for each partner) must be used during treatment and for 6 months after stopping therapy. During this time, women will have monthly pregnancy tests to ensure they are not pregnant. Tell your doctor immediately if you or your partner becomes pregnant while using this medication.
