Dosage and Administration
2 DOSAGE AND ADMINISTRATION Adults: 300 mg daily, administered as either 150 mg twice daily or 300 mg once daily. ( 2.1 ) Pediatric Patients Aged 3 Months and Older: Administered either once or twice daily. Dose should be calculated on body weight (kg) and should not exceed 300 mg daily. ( 2.2 ) Patients with Renal Impairment: Doses of lamivudine must be adjusted in accordance with renal function. ( 2.3 ) 2.1 Recommended Dosage for Adult Patients The recommended dosage of lamivudine in HIV-1-infected adults is 300 mg daily, administered as either 150 mg taken orally twice daily or 300 mg taken orally once daily with or without food. If lamivudine is administered to a patient infected with HIV-1 and HBV, the dosage indicated for HIV-1 therapy should be used as part of an appropriate combination regimen [see Warnings and Precautions ( 5.1 )] . 2.2 Recommended Dosage for Pediatric Patients Lamivudine scored tablet is the preferred formulation for HIV-1-infected pediatric patients who weigh at least 14 kg and for whom a solid dosage form is appropriate. Before prescribing lamivudine scored tablets, pediatric patients should be assessed for the ability to swallow tablets. For patients unable to safely and reliably swallow lamivudine tablets, the oral solution formulation may be prescribed [see Warnings and Precautions ( 5.5 )] . The recommended oral dosage of lamivudine tablets for HIV-1-infected pediatric patients is presented in Table 1. Table 1.

Consider HIV-1 viral load and CD4+ cell count/percentage when selecting the dosing interval for patients initiating treatment with oral solution [see Warnings and Precautions ( 5.5 ), Clinical Pharmacology ( 12.3 )]. 2.3 Patients with Renal Impairment Dosing of lamivudine is adjusted in accordance with renal function. Dosage adjustments are listed in Table 2 [see Clinical Pharmacology ( 12.3 )] . Table 2. Adjustment of Dosage of Lamivudine in Adults and Adolescents (Greater than or Equal to 25 kg) in Accordance with Creatinine Clearance Creatinine Clearance (mL/min) Recommended Dosage of Lamivudine ≥50 150 mg twice daily or 300 mg once daily 30-49 150 mg once daily 15-29 150 mg first dose, then 100 mg once daily 5-14 150 mg first dose, then 50 mg once daily <5 50 mg first dose, then 25 mg once daily No additional dosing of lamivudine is required after routine (4-hour) hemodialysis or peritoneal dialysis. Although there are insufficient data to recommend a specific dose adjustment of lamivudine in pediatric patients with renal impairment, a reduction in the dose and/or an increase in the dosing interval should be considered.
