Using standard and ultrasensitive techniques, we detected nonnucleoside reverse-transcriptase inhibitor–associated resistance mutations in 11 (20%) of 54 subjects who discontinued virologically suppressive nonnucleoside reverse-transcriptase inhibitor–containing antiretroviral therapy. Resistance was detected in 45% and 14% of subjects with a baseline human immunodeficiency virus type 1 RNA level of 51–400 copies/mL and ≤50 copies/mL, respectively. Mutations remained detectable for at least 48 weeks in some subjects.
