Harvoni is a combination of ledipasvir and sofosbuvir and is used to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. It may sometimes be used with another antiviral medication (ribavirin). These drugs work by reducing the amount of hepatitis C virus in your body, which helps your immune system fight the infection and may help your liver recover. Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis), or liver cancer.
It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice “safer sex” (including the use of latex condoms) to lower the risk of passing the virus to others.
How to use Harvoni
Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start taking Harvoni 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. The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on weight.
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. 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 30 minutes.
This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same time each day.
Tell your doctor if you vomit within 5 hours after taking this medication. You may need to take another dose. Continue to take Harvoni 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 ledipasvir. 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 ledipasvir from working. Ask your doctor or pharmacist how to use these medications safely.
How to Spot Fake Harvoni
