- Dosage
- **2 DOSAGE AND ADMINISTRATION**
**2.1 Testing Prior to Initiation of VIREAD for Treatment of HIV-1 Infection or Chronic Hepatitis B**
Prior to or when initiating VIREAD, test patients for HBV infection and HIV-1 infection. VIREAD alone should not be used in patients with HIV-1 infection _\[see Warnings and Precautions (5.3)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]_.
Prior to initiation and during use of VIREAD, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus _\[see Warnings and Precautions (5.2)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]_.
**2.2 Recommended Tablet Dosage in Adults and Pediatric Patients 12 Years of Age and Older (35 kg or more)**
The recommended dosage of VIREAD in adults and pediatric patients weighing at least 35 kg is one 300 mg tablet taken orally, once daily without regard to food. The dosage for VIREAD is the same for both HIV and HBV indications.
In the treatment of chronic hepatitis B, the optimal duration of treatment is unknown. Safety and efficacy in pediatric patients with chronic hepatitis B weighing less than 35 kg have not been established.
**2.3 Dosage Adjustment in Patients with Renal Impairment**
Significant increase in drug exposures occurred when VIREAD was administered to subjects with moderate to severe renal impairment (creatinine clearance below 50 mL/min). Table 1 provides dosage interval adjustment for patients with renal impairment. No dosage adjustment is necessary for patients with mild renal impairment (creatinine clearance 50–80 mL/min) _\[see Warnings and Precautions (5.2), Use in Specific Populations (8.5), and Clinical Pharmacology (11.2)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]_.
No data are available to make dosage recommendations in patients with creatinine clearance below 10 mL/min who are not on hemodialysis.
No data are available to make dosage recommendations in pediatric patients 12 years of age and older with renal impairment.

- Indication Info
- **1 INDICATIONS AND USAGE**
**1.1 HIV-1 Infection**
VIREAD is indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults and pediatric patients 12 years of age and older.
The following points should be considered when initiating therapy with VIREAD for the treatment of HIV-1 infection:
- VIREAD should not be used in combination with DESCOVY®, GENVOYA®, STRIBILD®, TRUVADA® or other products containing tenofovir disoproxil fumarate (DF) or tenofovir alafenamide _\[See Warnings and Precautions (5.4)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]_.
**1.2 Chronic Hepatitis B**
VIREAD is indicated for the treatment of chronic hepatitis B virus (HBV) in adults and adolescents 12 to <18 years of age.
The following points should be considered when initiating therapy with VIREAD for the treatment of chronic hepatitis B infection:
The indication in adults is based on safety and efficacy data from treatment of subjects who were nucleoside-treatment-naïve and subjects who were treatment-experienced with documented resistance to lamivudine. Subjects were adults with HBeAg-positive and HBeAg-negative chronic hepatitis B with compensated liver disease _\[See Clinical Studies (13.2)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]_.
VIREAD was evaluated in a limited number of subjects with chronic hepatitis B and decompensated liver disease. _\[See Adverse Reactions (6.1), Clinical Studies (13.2)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]_
The numbers of subjects in clinical trials who had adefovir resistance-associated substitutions at baseline were too small to reach conclusions of efficacy _\[See Microbiology (11.3), Clinical Studies (13.2)_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _\]._
VIREAD is indicated for the treatment of chronic hepatitis B in adolescents 12 to <18 years of age with:
Compensated liver disease and evidence of immune active disease, i.e. active viral replication, persistently elevated serum ALT levels and histological evidence of active inflammation and/or fibrosis.
