What is Sovaldi?

Sovaldi (sofosbuvir) is an antiviral medication that prevents hepatitis C virus (HCV) from multiplying in your body.

Sovaldi is used to treat chronic hepatitis C in adults and children who are at least 3 years old.

Sovaldi must be given in combination with other antiviral medications (usually ribavirin with or without peginterferon alfa). It should not be used alone.

Sovaldi treats specific genotypes of hepatitis C, and only in certain people. Use only the medications prescribed for you. Do not share your medicine with other people.

Sovaldi is sometimes used in people who also have HIV, or people who have liver cancer and are going to have a liver transplant. This medicine is not a treatment for HIV or AIDS.

Important Information

If you've ever had hepatitis B, it may become active or get worse while using or after you stop using Sovaldi. You may need frequent liver function tests for several months.

Sovaldi is used in combination with other medication. 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.

Sovaldi can cause birth defects or death in an unborn baby. Do not use Sovaldi 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.

Before taking this medicine

You should not use Sovaldi if you are allergic to sofosbuvir. When taking Sovaldi with other medicine: To make sure all medicines are safe for you, tell your doctor about all your medical conditions, and if you are pregnant or breastfeeding.

To make sure Sovaldi is safe for you, tell your doctor if you have ever had:

  • hepatitis B (you may be tested for this before you take sofosbuvir);

  • a liver transplant;

  • liver problems other than hepatitis C;

  • kidney disease (or if you are on dialysis);

  • HIV or AIDS;

  • a heart rhythm problem for which you take a medicine called amiodarone; or

  • if you use a blood thinner (warfarin, Coumadin, Jantoven) and you have routine "INR" or prothrombin time tests.

Sovaldi is sometimes used in combination with ribavirin. Both men and women using ribavirin should use effective birth control to prevent pregnancy. Ribavirin can cause birth defects, miscarriage, or death to an unborn baby if the mother or father is using this medicine.

You should not take ribavirin if you are pregnant, or if you are a man and your sex partner is pregnant. Use effective birth control to prevent pregnancy. Keep using birth control for at least 6 months after your last dose of ribavirin.

Tell your doctor right away if a pregnancy occurs while either the mother or the father is using ribavirin.

It may not be safe to breastfeed while using Sovaldi. Ask your doctor about any risk.

Sovaldi is not approved for use by anyone younger than 3 years old.

How should I take Sovaldi?

Sovaldi must be given in combination with other antiviral medications and it should not be used alone.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Take the medicine at the same time each day, with or without food.

Do not chew Sovaldi oral pellets. To take with food, you may mix the pellets with a non-acidic soft food (pudding, chocolate syrup, mashed potato, ice cream) that is at room temperature or below. Swallow the mixture without chewing, no more than 30 minutes after mixing. Do not save the mixture for later use.

Sofosbuvir doses are based on weight in children. Your child's dose needs may change if the child gains or loses weight.

You will need frequent blood tests to check your liver function.

If you've ever had hepatitis B, this virus may become active or get worse while you are using Sovaldi or in the months after you stop. You may need liver function tests for several months after your last dose.

You should not stop using Sovaldi suddenly. Stopping suddenly could make your hepatitis C harder to treat with antiviral medicine.

Use all medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor's advice. Every person with chronic hepatitis C should remain under the care of a doctor.

Store this medicine in the original container at room temperature away from moisture and heat. Do not open the packet of oral pellets until you are ready to use the medicine.
