In addition to initial laboratory testing, clinics offering same-day PrEP should be able to provide: (1) assistance for patients to enroll in health insurance or a medication assistance program (eg, Ready, Set, PrEP) for those ineligible for insurance coverage, (2) rapid follow-up on all laboratory results with reliable patient contact information, and (3) follow-up appointments with clinicians able to prescribe and administer PrEP medications.
Off-label “on-demand” PrEP.An off-label treatment regimen for men who have sex with men (MSM) is termed “on-demand” PrEP or “2-1-1 PrEP” and is included in the CDC guidelines for consideration by clinicians.5 This alternative dosing schedule can be used for individuals who have sex less frequently and in a more planned fashion.
On-demand PrEP requires a patient to take 2 tablets of Truvada 2 to 24 hours before sex, followed by 1 tablet 24 hours and 1 tablet 48 hours after sexual activity. If a sexual act occurs at 48 hours, the patient should extend the daily dose for 48 additional hours, such that PrEP is always used daily for 48 hours after the last sex act.
This method has been studied with Truvada in MSM in Europe and Canada through the IPERGAY and PREVENIR trials and shown to have ≥ 86% efficacy in preventing HIV acquisition.11,12 The only US-based study showed lower efficacy; however, based on the currently available data, the International Antiviral Society-USA Panel has recommended it as an alternative regimen.13,14
PrEP via telehealth.Visits for PrEP initiation and continuation can be completed via telehealth.5 Patients then can complete necessary laboratory tests by going to a physical laboratory location or using mailed specimen kits in which they can self-collect urine, oral/rectal swabs, and fingerstick blood samples.
