Concerns about HAART (Highly Active Anti-Retroviral Therapy)

Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTI)

These drugs supposedly also inhibit the reverse transcriptase enzyme, but without emulating a nucleoside (DNA building block). They also have severe toxicity. Nevirapine is the most famous of these drugs, and is also prescribed to pregnant women and children, like AZT. Another commonly prescribed NNRTI is Efavirenz.
