Introduction<\/strong><\/h2>\n\n\n\n

In the ongoing fight against HIV, one of the most powerful tools in prevention is PrEP<\/strong>, or Pre-Exposure Prophylaxis<\/strong>. When taken correctly, PrEP can reduce the risk of getting HIV from sex by over 99%<\/strong> and from injection drug use by at least 74%<\/strong>.<\/p>\n\n\n\n

Despite its proven effectiveness, PrEP is still underused\u2014largely due to lack of awareness, misconceptions, and stigma. This article breaks down everything you need to know about PrEP: how it works, who should consider taking it, and how to access it safely.<\/p>\n\n\n\n

What is PrEP?<\/strong><\/p>\n\n\n\n

PrEP (Pre-Exposure Prophylaxis)<\/strong> is a preventive medication<\/strong> for people who do not have HIV<\/strong> but are at high risk of being exposed to the virus. It involves taking an HIV medicine consistently to prevent infection<\/strong> before exposure occurs.<\/p>\n\n\n\n

Currently Approved PrEP Medications:<\/strong><\/p>\n\n\n\n

    \n
  1. Truvada\u00ae<\/strong> (tenofovir + emtricitabine) \u2013 for all populations<\/li>\n\n\n\n
  2. Descovy\u00ae<\/strong> (tenofovir alafenamide + emtricitabine) \u2013 for men and transgender women; not approved for people assigned female at birth for receptive vaginal sex<\/li>\n\n\n\n
  3. Apretude\u00ae<\/strong> \u2013 a long-acting injectable PrEP given every two months (after an initial startup period)<\/li>\n<\/ol>\n\n\n\n

    How Does PrEP Work?<\/strong><\/p>\n\n\n\n

    PrEP works by building up protective levels of HIV-fighting medication<\/strong> in your bloodstream and tissues. If HIV enters the body, the drug is there to block the virus from taking hold and replicating.<\/p>\n\n\n\n

      \n
    • When taken daily<\/strong>, or as prescribed, it creates a protective barrier<\/strong>.<\/li>\n\n\n\n
    • For people at risk, it dramatically lowers the chances of HIV infection<\/strong>, even if exposed.<\/li>\n<\/ul>\n\n\n\n

      Who Should Consider Taking PrEP?<\/strong><\/p>\n\n\n\n

      PrEP is recommended for individuals who are HIV-negative<\/strong> and have a substantial risk<\/strong> of acquiring HIV. You might benefit from PrEP if you:<\/p>\n\n\n\n
