RT is a 24 yo MSM pt and HIV negative. He is in a relationship with a HIV+ male. They last had anal sex 2 weeks ago and the condom broke. He is just now presenting to the doctor. What type of prophylaxis is warranted?

HIV testing is needed and then PrEP could be initiated. NOT PEP because PEP must be started within 72 hours of exposure (and this pt's was 2 weeks ago). Can't do anything about this exposure now-- the patient waited too long. Since pt is at high risk (serodiscordant), PrEP is more appropriate to prevent future exposures.

PrEP (after HIV testing is completed to confirm pt is negative) Last possible exposure was >72 hours ago, so PEP is not appropriate.

Preexposure prophylaxis (PrEP)

What is the only drug approved for PrEP?

Truvada (Tenofovir DF+Emtricitabine)

How soon after a HIV exposure should PEP be started?

within 72 hours (the sooner the better) *remember: PEP has only been shown to be effective if used within 72 hours; therefore, if the patient's last exposure was a week ago PEP is not appropriate
