Exclusion Criteria:

  • Patients requiring therapy with any of the following: Nephrotoxic agents (aminoglycoside antibiotics, IV amphotericin B, cidofovir, cisplatin, foscarnet, IV pentamidine, oral and IV vancomycin, oral and IV ganciclovir, other agents with significant nephrotoxic potential);Probenecid; Systemic chemotherapeutic agents; Systemic corticosteroids; Interleukin-2 (IL-2); Investigational agents (except on approval by Gilead Sciences); Drugs that interact with efavirenz (astemizole, terfenadine, dihydroergotamine, ergotamine, midazolam, triazolam, cisapride, rifampin, ergonovine, methylergonovine, voriconazole). Administration of any of the listed medications is not allowed throughout the duration of the study period.
  • Pregnant or lactating patients.
  • Evidence of a gastrointestinal malabsorption syndrome or chronic nausea or vomiting which may confer an inability to receive an orally administered medication.
  • Current alcohol or substance abuse judged by the investigator to potentially interfere with patient compliance.
  • Malignancy other than cutaneous Kaposi''''s sarcoma (KS) or basal cell carcinoma. Patients with biopsy-confirmed cutaneous KS are eligible, if they are not anticipated to require systemic therapy during the study.
  • Active, serious infections(other than HIV-1 infection) requiring parenteral antibiotic therapy.
  • Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the patient unsuitable for the study or unable to comply with the dosing requirements.
