Pre-exposure prophylaxis (PrEP) stands as a pivotal advancement in HIV prevention, offering a 99% reduction in transmission risk when used correctly. Available in oral and injectable forms, PrEP’s effectiveness hinges on adherence and accessibility. Despite challenges, innovations in delivery and affordability are enhancing its reach, empowering individuals to make informed health decisions and contribute to HIV prevention efforts.
Understanding PrEP as a Tool for HIV Prevention
Pre-exposure prophylaxis, commonly known as PrEP, is a groundbreaking medication designed to prevent HIV infection. It works by using antiretroviral drugs to stop the virus from reproducing and spreading within the body. When taken as prescribed, PrEP can reduce the risk of HIV transmission by approximately 99% (source). This makes it a highly effective tool for individuals at higher risk of acquiring HIV, such as those in sexual relationships with HIV-positive partners, individuals engaging in condomless sex with partners of unknown HIV status, sex workers, and people who inject drugs.
Forms and Effectiveness of PrEP
PrEP is available in two primary forms: oral pills and long-acting injections. Oral PrEP requires daily intake, while the injectable form is administered less frequently, typically every two months. Both forms are effective in preventing HIV, with the choice between them often depending on personal preference and lifestyle (source). Consistent use of PrEP is crucial for maintaining its effectiveness. Missing doses can lead to insufficient medication levels, reducing its ability to prevent HIV. Therefore, setting daily reminders can be beneficial for adherence.
Challenges and Innovations in PrEP Delivery
Despite its effectiveness, the potential of PrEP as a powerful HIV prevention tool has not been fully realized due to unmet needs and slow scale-up. Challenges in effective use and persistence have limited its global impact. However, new PrEP products and service delivery innovations could enhance access, uptake, and effective use (source). Offering a variety of PrEP options, including long-acting injectables like cabotegravir and lenacapavir, can address individual preferences and improve prevention outcomes. Differentiated service delivery models, such as peer-led, pharmacy-based, and telehealth approaches, are crucial for improving PrEP accessibility and user satisfaction.
Considerations for PrEP Use
Before starting PrEP, it is essential to undergo an HIV test to confirm a negative status, as PrEP is not suitable for individuals already living with HIV. Using PrEP in such cases can lead to drug resistance, complicating future treatment options (source). Additionally, while PrEP is highly effective against HIV, it does not prevent other sexually transmitted infections (STIs). Therefore, users should continue practicing safe sex, such as using condoms and scheduling regular sexual health check-ups.
Access and Affordability of PrEP
PrEP has become more affordable and accessible, with most health insurance and Medicaid plans covering it. Assistance programs are available for those who are uninsured or underinsured to help with costs (source). For those without insurance or who cannot afford PrEP, drug manufacturer co-payment assistance, state PrEP assistance programs, and patient assistance programs are available to facilitate access to PrEP via telemedicine.

Understanding PrEP and its role in HIV prevention is crucial for individuals at risk of HIV exposure. With its high effectiveness and various forms, PrEP offers a reliable method to significantly reduce the risk of HIV transmission. However, challenges in accessibility and adherence remain, highlighting the need for continued innovation and support in PrEP delivery. By staying informed about PrEP, individuals can make educated decisions about their health and contribute to broader efforts in reducing new HIV acquisitions. Exploring the latest developments in PrEP can empower individuals to take proactive steps in safeguarding their health and the health of their communities.
