Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start taking sofosbuvir/velpatasvir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once daily. Children's dosage is based on age and weight. The manufacturer recommends that children younger than 6 years old take the pellet form of this medication with food to improve taste of the medication.
If you are using the pellet form of this medication, gently shake the packet before use. To take this medication without food, open the packet and pour the pellets directly into your mouth. To prevent a bitter taste, swallow the pellets without chewing. You may drink water after swallowing the pellets if needed. Repeat these steps if your dose is for more than one packet. If you are taking this medication with food, open the packet(s) and pour the pellets into a small bowl with one or more spoonfuls of non-acidic soft food (such as pudding, mashed potato, ice cream). The soft food should be at or below room temperature. After gently mixing, take all of the mixture without chewing within 15 minutes. Chewing or waiting to give the dose may make this medication taste bitter.
This medication works best when the amount of drug in your body is kept at a constant level. Take this drug at evenly spaced intervals. To help you remember, take it at the same time each day.
Continue to take sofosbuvir/velpatasvir for the full length of time prescribed, even if symptoms disappear after a short time. Stopping the medication too early may result in a return of the infection.
Antacids lower the absorption of velpatasvir. If you are taking an antacid, take it at least 4 hours before or 4 hours after this medication.
Other acid-lowering medications for indigestion, heartburn, or ulcers (such as prescription or over-the-counter medications including famotidine, omeprazole) may prevent velpatasvir from working. Ask your doctor or pharmacist how to use these medications safely.
