Patients who have decided to initiate treatment after consultation with their physician and after careful review of the Department of Health and Human Services (DHHS) guidelines for treatment will be considered for enrollment as research subjects. Individuals considered for enrollment providing informed consent (See Appendix A) will be screened and, if eligible, enrolled in the study. Adherence to study regimen and symptoms of hypersensitivity reactions will be monitored by self-report at each study visit. Adherence will be assessed using the standard ACTG Adherence Questionnaire II (See Appendix B), either over the telephone or during a clinic visit. Those patients reporting problems with adherence will be counseled and monitored closely every 4 weeks at clinic visits with phone consultation bi-weekly until adherence improves. If despite counseling, adherence is not maintained, patients will be discontinued from the study due to increased risk of drug resistance. AEs will be monitored closely to determine if appropriate management affects tolerability and adherence, i.e., prescribing anti-emetic or anti-diarrhea medications for nausea and diarrhea, respectively. Patients will be counseled on the importance of adherence at every study visit.
