Efavir (Efavirenz) is an important medicine used to treat HIV-1 infection. It belongs to the group of medicines called non-nucleoside reverse transcriptase inhibitors (NNRTIs). Efavirenz blocks the action of the reverse transcriptase enzyme, which the virus needs to multiply. As a result, the amount of HIV in the blood goes down. Health experts, including the World Health Organization (WHO), recommend Efavirenz as part of HIV treatment plans.
