3. Uses and benefits of Sustiva

Sustiva, also known by its generic name efavirenz, is a highly effective antiviral medication that is primarily used for the treatment of HIV (Human Immunodeficiency Virus) infection. As a non-nucleoside reverse transcriptase inhibitor (NNRTI), Sustiva works by inhibiting the reverse transcriptase enzyme, which is essential for the replication and spread of the virus within the body.

Here are some of the main uses and benefits of Sustiva:
