You may already be infected with hepatitis B (a virus that infects the liver and may cause severe liver damage), but not have any symptoms of the disease. In this case, taking the combination of sofosbuvir and velpatasvir may increase the risk that your infection will become more serious or life-threatening and you will develop symptoms. Tell your doctor if you have or ever had a hepatitis B virus infection. Your doctor will order a blood test to see if you have or have ever had hepatitis B infection. Your doctor will also monitor you for signs of hepatitis B infection during and for several months after your treatment. If necessary, your doctor may give you medication to treat this infection before and during your treatment with the combination of sofosbuvir and velpatasvir. If you experience any of the following symptoms during or after your treatment, call your doctor immediately: excessive tiredness, yellowing of the skin or eyes, loss of appetite, nausea or vomiting, pale stools, stomach pain, or dark urine.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests before, during, and after your treatment to check your body's response to the combination of sofosbuvir and velpatasvir.
Talk to your doctor about the risk(s) of taking the combination of sofosbuvir and velpatasvir.

The combination of sofosbuvir and velpatasvir is used alone or with ribavirin (Copegus, Rebetol, Ribasphere) to treat chronic hepatitis C (an ongoing viral infection that damages the liver). Sofosbuvir is in a class of antiviral medications called nucleotide hepatitis C virus (HCV) NS5B polymerase inhibitors. Velpatasvir is in a class of antiviral medications called HCV NS5A replication complex inhibitors. The combination of sofosbuvir and velpatasvir works by stopping the virus that causes hepatitis C from spreading inside the body.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them.  However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community.  See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
