Adults
The recommended dose for nevirapine is 200 mg once daily for the first 14 days (this lead-in period should be used because it has been found to lessen the frequency of rash), followed by 200 mg twice daily, in combination with other antiretroviral agents. For concomitantly administered antiretroviral therapy, the full prescribing information for those drugs should be consulted.
Pediatric patients
The recommended oral dose for pediatric patients aged 15 days and older is 150 mg/m 2 once daily for 14 days followed by 150 mg/m 2 twice daily thereafter. The total daily dose should not exceed 400 mg for any patient .

Table 1: Calculation of the Volume of NEVIMUNE Oral Suspension (50 mg/5 mL) Required for Pediatric Dosing Based on Body Surface and a Dose of 150 mg/m 2
NEVIMUNE Oral suspension should be shaken gently prior to administration. It is important to administer the entire measured dose of suspension by using an oral dosing syringe or dosing cup. An oral dosing syringe is recommended, particularly for volumes of 5 ml or less. If a dosing cup is used, it should be thoroughly rinsed with water and the rinse should also be administered to the patient.
Monitoring of patients
Intensive clinical and laboratory monitoring, including liver function tests, is essential at baseline and during the first 18 weeks of treatment with nevirapine. The optimal frequency of monitoring during this period has not been established. Some experts recommend clinical and laboratory monitoring more often than once per month, and in particular, would include monitoring of liver function tests at baseline, prior to dose escalation, and at 2 weeks post-dose escalation. After the initial 18-week period, frequent clinical and laboratory monitoring should continue throughout nevirapine treatment (see WARNINGS AND PRECAUTIONS ). In some cases, hepatic injury has progressed despite discontinuation of treatment.
Dosage Adjustment
Patients with Rash
Nevirapine should be discontinued if patients experiences severe rash or any rash accompanied by constitutional findings (see WARNINGS AND PRECAUTIONS ). A patient experiencing mild to moderate rash without constitutional symptoms during the 14-day lead-in period of 200 mg/day (4 mg/kg/day in pediatric patients) should not have their nevirapine dose increased until the rash has resolved (see WARNINGS AND PRECAUTIONS ) . The total duration of the once daily lead-in dosing period should not exceed 28 days, after which point an alternative regimen should be sought.
Patients with Hepatic Events
If a clinical (symptomatic) hepatic event occurs, nevirapine should be permanently discontinued. Do not restart nevirapine after recovery (see WARNINGS AND PRECAUTIONS ).
Patients with Dose Interruption
Patients who interrupt nevirapine dosing for more than 7 days should restart the recommended dosing, using one 200 mg tablet daily (4 mg/kg/day in pediatric patients) for the first 14 days (lead-in) followed by one 200 mg tablet twice daily (4 or 7 mg/kg twice daily, according to age, for pediatric patients).
Patients on Dialysis
An additional 200 mg dose of nevirapine following each dialysis treatment is indicated in patients receiving dialysis. Nevirapine metabolites may accumulate in patients receiving dialysis; however, the clinical significance of this accumulation is not known. Patients with CrCL ≥ 20 mL/min do not require an adjustment in nevirapine dosing. |
