药物是否可以预防HIV

If you are at very high risk for HIV from sex or injecting drugs, taking HIV medicines daily, calledpre-exposure prophylaxis (or PrEP), can greatly reduce your risk of HIV infection. You can combine additional strategies with PrEP to reduce your risk even further.

Federal guidelines recommend that PrEP be considered for people who are HIV-negative and at very high risk for HIV. This includes anyone who is in an ongoing sexual relationship with an HIV-positive partner. It also includes anyone who:

1. Is not in a mutually monogamous* relationship with a partner who recently tested HIV-negative, and
2. Is a
   • gay or bisexual man who has had anal sex without a condom or been diagnosed with an STD in the past 6 months;
   • man who has sex with both men and women; or
   • heterosexual man or woman who does not regularly use condoms during sex with partners of unknown HIV status who are at substantial risk of HIV infection (for example, people who inject drugs or women who have bisexual male partners).

PrEP is also recommended for people who’ve injected drugs in the past 6 months and have shared needles or works or been in drug treatment in the past 6 months.

If you have a partner who is HIV-positive and are considering getting pregnant, talk to your doctor about PrEP. It may be an option to help protect you and your baby.

PrEP involves daily medication and regular visits to a health care provider.
