We surveyed 970 PrEPX study participants to evaluate interest in switching from daily to on-demand PrEP in a study setting. Interested respondents (n = 469, 48%) more commonly reported PrEP cessation (adjusted odds ratio [aOR], 3.0; P <. 001), difficulty with adherence (aOR, 1.6; P =. 029), infrequent sex (aOR, 3.7; P <. 001), and toxicity concerns (aOR, 2.7; P <. 001).
