Post-Exposure Prophylaxis (PEP)

PEP involves taking a short course of antiretroviral drugs, usually for a month, after a high-risk exposure to HIV. For maximum effectiveness, PEP should be started immediately—and no more than 72 hours—after possible exposure. The Centers for Disease Control and Prevention (CDC) recommends the following preferred HIV PEP regimen:


DRUG: Isentress (raltegravir)
DOSING INFO

One tablet twice a day. Each tablet contains 400 mg of raltegravir.

PLUS


DRUG: Truvada (tenofovir disoproxil fumarate + emtricitabine)

One tablet once a day. Each tablet contains 300 mg tenofovir disoproxil fumarate + 200 mg emtricitabine.

 Alternative PEP regimens can be found online in the CDC’s PEP Guidelines.
