Sovaldi® (sofosbuvir) is a prescription drug that is combined with other drugs to treat people with chronic hepatitis C virus (HCV) infection. Sovaldi is a direct-acting antiviral (DAA).1-3
What are the ingredients in Sovaldi?
The active ingredient in Sovaldi is sofosbuvir.2
How does Sovaldi work?
The hepatitis C virus multiplies in the body, causing the liver to become inflamed and damaged. If left untreated, that liver damage can cause a serious problem called cirrhosis. As cirrhosis gets worse, it can cause liver failure, liver cancer, and other serious problems.1-3
Sovaldi is a DAA that targets NS5B. NS5B is a substance HCV needs to grow (replicate). By blocking the virus’ ability to grow, Sovaldi reduces the amount of virus in the body. When combined with other drugs, Sovaldi can cure HCV in 12 weeks. For people with HCV, “cured” means the HCV virus is no longer detectable in the body 3 months after treatment stops. This is known as “SVR.”2,3
What are the possible side effects of Sovaldi?
Side effects can vary depending on the specific drugs you are taking in combination with Sovaldi.
In people treated with Sovaldi + ribavirin + peginterferon alfa, the most common side effects include:3
- Trouble sleeping
- Low red blood cell count (anemia)
In people treated with the combination of Sovaldi + ribavirin, the most common side effects include tiredness and headache.3
Sovaldi may also cause serious side effects. In people who have previously had hepatitis B, Sovaldi may reactivate this infection. Hepatitis B reactivation may result in liver damage, liver failure, and death. Before starting treatment with Sovaldi, your doctor should check you for hepatitis B infection.2,3
Sovaldi may cause a slow heart rate (bradycardia) in people who are taking amiodarone (Cordarone®, Nexterone®, Pacerone®). This medicine is used to treat certain heart problems. In some cases, bradycardia may lead to needing a pacemaker or death.3
These are not all the possible side effects of Sovaldi. Talk to your doctor about what to expect or if you experience any changes that concern you during treatment with Sovaldi.
