nevirapine has been researched along with Viremia in 24 studies
Nevirapine: A potent, non-nucleoside reverse transcriptase inhibitor used in combination with nucleoside analogues for treatment of HIV INFECTIONS and AIDS.
nevirapine : A dipyridodiazepine that is 5,11-dihydro-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepine which is substituted by methyl, oxo, and cyclopropyl groups at positions 4, 6, and 11, respectively. A non-nucleoside reverse transcriptase inhibitor with activity against HIV-1, it is used in combination with other antiretrovirals for the treatment of HIV infection.
Viremia: The presence of viruses in the blood.

"Switching subjects with persistently undetectable HIV-1 viremia under antiretroviral treatment (ART) to once-daily tenofovir/emtricitabine (or lamivudine) + nevirapine is a cost-effective and well-tolerated strategy." | 7.81 | Effectiveness of a Treatment Switch to Nevirapine plus Tenofovir and Emtricitabine (or Lamivudine) in Adults with HIV-1 Suppressed Viremia.

For those infants who were randomized at 6 weeks and who initiated study drug we looked at the frequency and severity of adverse reactions through 18 months of study. The severity of all AEs was graded according to the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events. The term severity is described as the intensity grade or level for specific event (i.e. mild, moderate, severe, or life-threatening). Severity is not the same as seriousness. (NCT00074412)
