1. Why am I using Sovaldi?

Sovaldi contains the active ingredient sofosbuvir. Sovaldi works together with other medicines by lowering the amount of hepatitis C virus in your body and may lead to a cure of your HCV infection over at least 12 weeks.

Cure means the HCV virus is cleared from your blood (remains at an undetectable level) when measured 3 months after finishing all treatment.

Sovaldi does not protect against re-infection with the HCV virus if cure has been achieved.

Sovaldi is used to treat hepatitis C virus (HCV) infection in adults 18 years and older.

Hepatitis C is a virus that infects the liver.

2. What should I know before I use Sovaldi?

Warnings

Do not use Sovaldi if:

  • you are allergic to sofosbuvir, or any of the ingredients listed at the end of this leaflet.
  • Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • Have liver problems, other than hepatitis C
  • Have a current or previous infection with the hepatitis B virus since your doctor may want to monitor you more closely.
  • Have HIV infection
  • Have kidney problems or if you are on haemodialysis.
  • Have diabetes
  • Have any other medical condition.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant. Sovaldi is commonly used together with ribavirin or with peginterferon alfa and ribavirin. Ribavirin can damage your unborn baby. It is therefore absolutely essential that you (and your partner) take all precautions not to get pregnant during this therapy. You and your partner must use an effective birth control method during ribavirin treatment and during the 6 months after ribavirin treatment. It is very important that you read the Pregnancy section in the ribavirin product information very carefully.

Talk to your doctor if you are breastfeeding or intend to breastfeed. It is not known whether sofosbuvir, the active ingredient of Sovaldi, pass into human breast milk.

Use in Children

Sovaldi is recommended for adults. Sovaldi has not been studied in children under 18 years of age.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Tell your doctor if you take any of the following medicines:

  • modafinil
  • amiodarone used to treat heart conditions
  • Warfarin or other similar medicines called vitamin K antagonists used to thin the blood.
  • carbamazepine, phenytoin (medicines used to treat epilepsy and prevent seizures)
  • rifampicin, rifapentine, rifabutin (antibiotics used to treat infections, including tuberculosis)
  • St. John's Wort (Hypericum perforatum – herbal medicine used to treat depression)
  • tipranavir used to treat HIV infection

SOVALDI may interact with these medicines. As a result, the amounts of SOVALDI or other medicines in your blood may be affected. This may stop your medicines from working properly, or make any side effects worse. In some cases your doctor may need to give you a different medicine or adjust the dose of medicine you are taking.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Sovaldi.

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Sofosbuvir was not genotoxic in a battery of in vitro or in vivo assays, including bacterial mutagenicity, chromosome aberration using human peripheral blood lymphocytes and in vivo mouse micronucleus assays. See also the product information for ribavirin and peginterferon alfa.
Carcinogenicity. Carcinogenicity studies in mice and rats do not indicate any carcinogenicity potential of sofosbuvir administered at doses up to 200 mg/kg/day in male mice and 600 mg/kg/day in female mice and 750 mg/kg/day in rats. Exposure to GS-331007 in these studies in mice was up to 7 x (male) and 30 x (female) and in rats up to 13 x (male) and 17 x (female) higher than the clinical exposure at 400 mg sofosbuvir.
