Dosage form: tablet, film coated

Medically reviewed by Drugs.com. Last updated on Mar 12, 2020.

Testing Prior to the Initiation of Therapy

Test all patients for evidence of current or prior HBV infection by measuring hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) before initiating HCV treatment with SOVALDI [see Warnings and Precautions (5.1)].

Recommended Dosage in Adults

The recommended dosage of SOVALDI is one 400 mg tablet, taken orally, once daily with or without food [see Clinical Pharmacology (12.3)].

Administer SOVALDI in combination with ribavirin or in combination with pegylated interferon and ribavirin for the treatment of HCV. The recommended treatment regimen and duration for SOVALDI combination therapy is provided in Table 1.

For patients with HCV/HIV-1 coinfection, follow the dosage recommendations in Table 1. Refer to Drug Interactions (7) for dosage recommendations for concomitant HIV-1 antiviral drugs.

See peginterferon alfa prescribing information for dosage recommendation for patients with genotype 1 or 4 HCV.
Dosage of ribavirin is weight-based (<75 kg = 1000 mg and ≥75 kg = 1200 mg). The daily dosage of ribavirin is administered orally in two divided doses with food. Patients with renal impairment (CrCl ≤50 mL/min) require ribavirin dosage reduction; refer to ribavirin tablet prescribing information.
Treatment-experienced patients have failed an interferon-based regimen with or without ribavirin.
Genotype 1 or 4 Treatment-naïve without cirrhosis or with compensated cirrhosis (Child-Pugh A) SOVALDI + peginterferon alfa* + ribavirin 12 weeks
Genotype 2 Treatment-naïve and treatment-experienced without cirrhosis or with compensated cirrhosis
(Child-Pugh A)
SOVALDI + ribavirin 12 weeks
Genotype 3 Treatment-naïve and treatment-experienced without cirrhosis or with compensated cirrhosis
(Child-Pugh A)
SOVALDI + ribavirin 24 weeks

Patients with Genotype 1 HCV Who are Ineligible to Receive an Interferon-Based Regimen

SOVALDI in combination with ribavirin for 24 weeks can be considered as a therapeutic option for patients with genotype 1 infection who are ineligible to receive an interferon-based regimen [see Clinical Studies (14.4)]. Treatment decision should be guided by an assessment of the potential benefits and risks for the individual patient.

Patients with Hepatocellular Carcinoma Awaiting Liver Transplantation

Administer SOVALDI in combination with ribavirin for up to 48 weeks or until the time of liver transplantation, whichever occurs first, to prevent post-transplant HCV reinfection [see Use in Specific Populations (8.8)].

Recommended Dosage in Pediatric Patients 3 Years of Age and Older with Genotype 2 or 3 HCV

The recommended treatment regimen, duration, and recommended dosage for SOVALDI combination therapy is provided in Table 2 and Table 3. Table 4 provides the weight-based dosage of ribavirin when used in combination with SOVALDI for pediatric patients. For patients with HCV/HIV-1 coinfection, follow the dosage recommendations in Table 3 and Table 4. Refer to Drug Interactions (7) for dosage recommendations for concomitant HIV-1 antiviral drugs. In pediatric patients with hepatocellular carcinoma awaiting liver transplantation, administer SOVALDI in combination with ribavirin for up to 48 weeks or until the time of liver transplantation, whichever occurs first, to prevent post-transplant HCV reinfection [see Use in Specific Populations (8.8)].

SOVALDI + ribavirin 12 weeks
Genotype 3 Treatment-naïve and treatment-experienced* without cirrhosis or with compensated cirrhosis
(Child-Pugh A)
SOVALDI + ribavirin 24 weeks

The recommended dosage of SOVALDI in pediatric patients 3 years and older with genotype 2 or 3 HCV using SOVALDI tablets or oral pellets (with or without food) is based on weight (Table 3), and is to be taken orally once daily in combination with ribavirin [see Dosage and Administration (2.4), Use in Specific Populations (8.4), Clinical Pharmacology (12.3), and Clinical Studies (14.5)]. SOVALDI pellets can be taken by pediatric patients who cannot swallow the tablet formulation [see Dosage and Administration (2.4)].

Preparation and Administration of Oral Pellets

See the SOVALDI oral pellets full Instructions for Use for details on the preparation and administration of SOVALDI pellets.

Do not chew SOVALDI pellets. If SOVALDI pellets are administered with food, sprinkle the pellets on one or more spoonfuls of non-acidic soft food at or below room temperature. Examples of non-acidic foods include pudding, chocolate syrup, mashed potato, and ice cream. Take SOVALDI pellets within 30 minutes of gently mixing with food and swallow the entire contents without chewing to avoid a bitter aftertaste.

Dosage Modification

Dosage reduction of SOVALDI is not recommended.

If a patient has a serious adverse reaction potentially related to peginterferon alfa and/or ribavirin, the peginterferon alfa and/or ribavirin dosage should be reduced or discontinued, if appropriate, until the adverse reaction abates or decreases in severity. Refer to the peginterferon alfa and ribavirin prescribing information for additional information about how to reduce and/or discontinue the peginterferon alfa and/or ribavirin dosage.

Discontinuation of Dosing

If the other agents used in combination with SOVALDI are permanently discontinued, SOVALDI should also be discontinued.

Severe Renal Impairment and End Stage Renal Disease

No dosage recommendation can be given for patients with severe renal impairment (estimated Glomerular Filtration Rate [eGFR] less than 30 mL/min/1.73m2) or with end stage renal disease (ESRD) due to higher exposures (up to 20-fold) of the predominant sofosbuvir metabolite [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].
