Efavirenz Teva(efavirenz)

Efavirenz is indicated in antiviral combination treatment of human-immunodeficiency-virus-1 (HIV-1)-infected adults, adolescents and children 3 years of age and older. Efavirenz has not been adequately studied in patients with advanced HIV disease, namely in patients with CD4 counts < 50 cells/mm3, or after failure of protease inhibitor (PI)-containing regimens. Although cross-resistance of efavirenz with protease inhibitors (PIs) has not been documented, there are at present insufficient data on the efficacy of subsequent use of PI-based combination therapy after failure of regimens containing efavirenz.
