 PrEP should not be offered as a sole intervention and should include counseling and education about:  Consistent and correct condom use  Safer-sex practices and risk-reduction counseling  Intravenous drug use (IVD), harm reduction methods  Adherence to PrEP  Importance of frequent HIV testing and screening of STIs that can facilitate HIV transmission  For sero-discordant couples, the importance of suppressive ART for HIV-infected partners exposure-prophylaxis-prep-to-prevent-hiv-transmission/

 PrEP is indicated for individuals who have a documented negative HIV test and are at ongoing, high risk for HIV infection  Negative, HIV test result needs to be confirmed as close to initiation of PrEP as possible  PrEP is not meant to be used as a lifelong intervention, but rather as a method of increasing prevention during “high risk” periods exposure-prophylaxis-prep-to-prevent-hiv-transmission/

 PrEP as daily fixed-dose tenofovir-emtricitabine has a strong evidence basis in multiple populations of individuals at high- risk for HIV-infection (heterosexual, MSM, IVDs)  Needs to be prescribed as part of a comprehensive prevention plan that includes use of condoms, harm reduction for IVDs  Strong consideration should be given to its use in populations as defined by NYS DOH and the CDC  Both providers and patients are open to the idea of its use  Insurance plans are covering the cost of drug, though prior authorization may be necessary
