DOSAGE AND ADMINISTRATION
Recommended Dosage For Adult Patients
The recommended dosage of EPIVIR 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].
Recommended Dosage For Pediatric Patients
The recommended dosage of EPIVIR oral solution in HIV-1-infected pediatric patients aged 3 months and older is 4 mg per kg taken orally twice daily or 8 mg per kg taken orally once daily (up to a maximum of 300 mg daily), administered in combination with other antiretroviral agents. Consider HIV-1 viral load and CD4+ cell count/percentage when selecting the dosing interval for patients initiating treatment with oral solution [see CLINICAL PHARMACOLOGY].
EPIVIR is also available as a scored tablet for HIV-1-infected pediatric patients who weigh at least 14 kg and for whom a solid dosage form is appropriate. Before prescribing EPIVIR tablets, children should be assessed for the ability to swallow tablets. If a child is unable to reliably swallow EPIVIR tablets, the oral solution formulation should be prescribed. The recommended oral dosage of EPIVIR tablets for HIV-1-infected pediatric patients is presented in Table 1.

(150-mg) Tablets in Pediatric Patients

dosing after 36 weeks of treatment [see Clinical Studies].
b Patients may alternatively take one 300-mg tablet, wData regarhich is not scored.
Patients With Renal Impairment
Dosing of EPIVIR is adjusted in accordance with renal function. Dosage adjustments are listed in Table 2 [see CLINICAL PHARMACOLOGY].
Table 2: Adjustment of Dosage of EPIVIR in Adults and
Adolescents (Greater than or Equal to 25 kg) in Accordance with Creatinine
|Creatinine Clearance (mL/min)||Recommended Dosage of EPIVIR|
|> 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|
Although there are insufficient data to recommend a specific dose adjustment of EPIVIR in pediatric patients with renal impairment, a reduction in the dose and/or an increase in the dosing interval should be considered.
