DOSAGE AND ADMINISTRATION
The recommended dosage of SUSTIVA (efavirenz) is 600 mg orally, once daily, in combination with a protease inhibitor and/or nucleoside analogue reverse transcriptase inhibitors (NRTIs). It is recommended that SUSTIVA be taken on an empty stomach, preferably at bedtime. The increased efavirenz concentrations observed following administration of SUSTIVA with food may lead to an increase in frequency of adverse reactions [see CLINICAL PHARMACOLOGY]. Dosing at bedtime may improve the tolerability of nervous system symptoms [see WARNINGS AND PRECAUTIONS, ADVERSE REACTIONS, and PATIENT INFORMATION]. SUSTIVA capsules or tablets should be swallowed intact with liquid. For patients who cannot swallow capsules or tablets, the capsule sprinkle method of administration is recommended.
Concomitant Antiretroviral Therapy
If SUSTIVA is coadministered with voriconazole, the voriconazole maintenance dose should be increased to 400 mg every 12 hours and the SUSTIVA dose should be decreased to 300 mg once daily using the capsule formulation (one 200 mg and two 50 mg capsules or six 50 mg capsules). SUSTIVA tablets should not be broken. See DRUG INTERACTIONS, Table 6 and CLINICAL PHARMACOLOGY, Tables 8 and 9).
If SUSTIVA is coadministered with rifampin to patients weighing 50 kg or more, an increase in the dose of SUSTIVA to 800 mg once daily is recommended [see DRUG INTERACTIONS, Table 6 and CLINICAL PHARMACOLOGY, Table 9].
It is recommended that SUSTIVA be taken on an empty stomach, preferably at bedtime. Table 1 describes the recommended dose of SUSTIVA for pediatric patients 3 months of age or older and weighing between 3.5 kg and 40 kg [see CLINICAL PHARMACOLOGY The recommended dosage of SUSTIVA for pediatric patients weighing 40 kg or greater is 600 mg once daily. For pediatric patients who cannot swallow capsules, the capsule contents can be administered with a small amount of food or infant formula using the capsule sprinkle method of administration.

Capsule Sprinkle Method of Administration
For pediatric patients at least 3 months old and weighing at least 3.5 kg and adults who cannot swallow capsules or tablets, the capsule contents may be administered with a small amount (1 to 2 teaspoons) of food. Use of infant formula for mixing should only be considered for those young infants who cannot reliably consume solid foods. Patients and caregivers must be instructed to open the capsule carefully to avoid spillage or dispersion of the capsule contents into the air. The capsule should be held horizontally over a small container and carefully twisted to open. For patients able to tolerate solid foods, the entire capsule contents should be gently mixed with an age-appropriate soft food, such as applesauce, grape jelly, or yogurt, in the small container. For young infants receiving the capsule sprinkle-infant formula mixture, the entire capsule contents should be gently mixed into 2 teaspoons (10 mL) of reconstituted room temperature infant formula in a medicine cup by carefully stirring with a small spoon, and then drawing up the mixture into a 10 mL oral dosing syringe for administration. After administration of the SUSTIVA-food or -formula mixture, an additional small amount (approximately 2 teaspoons) of food or formula must be added to the empty mixing container, stirred to disperse any remaining SUSTIVA residue, and administered to the patient. The SUSTIVA-food or -formula mixture should be administered within 30 minutes of mixing. No additional food should be consumed for 2 hours after administration of SUSTIVA.
Further patient instructions on the capsule sprinkle method of administration are provided in the FDA-approved patient labeling (see PATIENT INFORMATION and Instructions for Use).
