What is ledipasvir and sofosbuvir?

Ledipasvir and sofosbuvir (brand name Harvoni) may be used to treat chronic hepatitis C virus (HCV) in adults and children aged 3 years and older. Ledipasvir sofosbuvir is used to treat the following types of HCV:

Your doctor will perform tests to find out which hepatitis genotype you have. The treatment duration of ledipasvir and sofosbuvir is usually 12 weeks.

Ledipasvir sofosbuvir contains 2 antivirals, ledipasavir and sofosbuvir which each have a different mechanism of action. Ledipasvir blocks the effects of an HCV protein that is required for the virus to multiply (called viral replication). Sofosbuvir is a prodrug, that is converted in the body to its active metabolite that uses an enzyme to incorporate itself into the RNA of HCV which also prevents the virus from making copies of itself. For more information about ledipasvir and sofosbuvir's mechanism of action see here.

Ledipasvir and sofosbuvir gained FDA approval for HCV on October 10, 2014, under the brand Harvoni.

Ledipasvir and sofosbuvir is available as Harvoni and as generic ledipasvir 90 mg and sofosbuvir 400 mg. There is no generic for the other strength (ledipasvir 45 mg sofosbuvir 200 mg) or for ledipasvir and sofosbuvir oral pellets. The pellets are only available as Harvoni.

Serious side effects and warnings

Ledipasvir and sofosbuvir carries a Boxed Warning for the risk of hepatitis B (HBV) reactivation in people coinfected with HCV and HBV. 

Hepatitis B virus (HBV) reactivation. Before starting treatment with ledipasvir and sofosbuvir, your healthcare provider will do blood tests to check for HBV. If you have ever had HBV, the hepatitis B virus could become active again during or after treatment of HCV with ledipasvir and sofosbuvir. Hepatitis B virus becoming active again (called reactivation) may cause serious liver problems including liver failure and death. Your healthcare provider will monitor you if you are at risk for hepatitis B virus reactivation during treatment and after you stop taking ledipasvir and sofosbuvir. Call your healthcare provider right away if you develop right-sided upper abdominal pain, vomiting, loss of appetite, or yellowing of your skin or eyes.

Slow heart rate (bradycardia). Ledipasvir and sofosbuvir may slow your heart rate and cause other symptoms when taken alongside other heart medications such as amiodarone (Cordarone, Nexterone, Pacerone). In some cases, this has led to death or the need for a heart pacemaker. Get medical help right away if you take amiodarone with ledipasvir and sofosbuvir and develop any of the following symptoms fainting or near-fainting, weakness, chest pains, dizziness or lightheadedness, extreme tiredness, confusion, not feeling well, shortness of breath, or memory problems.
