  2.1    Treatment of HIV-1 Infection

  Adults: The recommended oral dose of zidovudine is 600 mg/day in divided doses in combination with other antiretroviral agents.

  Pediatric Patients (Aged 4 Weeks to <18 Years): Healthcare professionals should pay special attention to accurate calculation of the dose of Zidovudine, transcription of the medication order, dispensing information, and dosing instructions to minimize risk for medication dosing errors.

  Prescribers should calculate the appropriate dose of zidovudine for each child based on body weight (kg) and should not exceed the recommended adult dose.

  Before prescribing Zidovudine Capsules or Tablets, children should be assessed for the ability to swallow capsules or tablets. If a child is unable to reliably swallow a Zidovudine Capsule or Tablet, the Zidovudine oral solution formulation should be prescribed.

  The recommended dosage in pediatric patients 4 weeks of age and older and weighing ≥4 kg is provided in Table 1. Zidovudine oral solution should be used to provide accurate dosage when whole tablets or capsules are not appropriate.

  Table 1: Recommended Pediatric Dosage of Zidovudine

  Body Weight (kg) Total Daily Dose Dosage Regimen and Dose Twice Daily Three Times Daily 4 to <9 24 mg/kg/day 12 mg/kg 8 mg/kg ≥ 9 to <30 18 mg/kg/day 9 mg/kg 6 mg/kg ≥ 30 600 mg/day 300 mg 200 mg

  Alternatively, dosing for zidovudine can be based on body surface area (BSA) for each child. The recommended oral dose of zidovudine is 480 mg/m2/day in divided doses (240 mg/m2 twice daily or 160 mg/m2 three times daily). In some cases the dose calculated by mg/kg will not be the same as that calculated by BSA.

  2.2    Prevention of Maternal-Fetal HIV-1 Transmission

  The recommended dosage regimen for administration to pregnant women (>14 weeks of pregnancy) and their neonates is:

  Maternal Dosing: 100 mg orally 5 times per day until the start of labor [see Clinical Studies (14.3)]. During labor and delivery, intravenous zidovudine should be administered at 2 mg/kg (total body weight) over 1 hour followed by a continuous intravenous infusion of 1 mg/kg/hour (total body weight) until clamping of the umbilical cord.

  Neonatal Dosing: Start neonatal dosing within 12 hours after birth and continue through 6 weeks of age. Neonates unable to receive oral dosing may be administered zidovudine intravenously. See Table 2.

  Table 2. Recommended Neonatal Dosages of Zidovudine

  Route Total Daily Dose Dose and Dosage Regimen Oral 8 mg/kg/day 2 mg/kg every 6 hours IV 6 mg/kg/day 1.5 mg/kg infused over 30 minutes, every 6 hours 2.3    Patients With Severe Anemia and/or Neutropenia

  Significant anemia (hemoglobin <7.5 g/dL or reduction >25% of baseline) and/or significant neutropenia (granulocyte count <750 cells/mm3 or reduction >50% from baseline) may require a dose interruption until evidence of marrow recovery is observed [see Warnings and Precautions (5.1)]. In patients who develop significant anemia, dose interruption does not necessarily eliminate the need for transfusion. If marrow recovery occurs following dose interruption, resumption in dose may be appropriate using adjunctive measures such as epoetin alfa at recommended doses, depending on hematologic indices such as serum erythropoetin level and patient tolerance.

  2.4    Patients With Renal Impairment

  End-Stage Renal Disease: In patients maintained on hemodialysis or peritoneal dialysis, the recommended dosage is 100 mg every 6 to 8 hours [see Clinical Pharmacology (12.3)].

  2.5    Patients With Hepatic Impairment

  There are insufficient data to recommend dose adjustment of zidovudine in patients with mild to moderate impaired hepatic function or liver cirrhosis.
