Following accidental exposure to blood from an HIV-positive patient, what treatment is recommended?

The recommended treatment following accidental exposure to blood from an HIV-positive patient is a 4-week, two-drug postexposure prophylaxis (PEP) regimen that should be initiated within 72 hours of the exposure. This approach is based on established guidelines aimed at reducing the risk of HIV infection after potential exposure.

PEP consists of antiretroviral medications that, when taken promptly and consistently for the full duration, can significantly decrease the likelihood of the virus taking hold in the body. The 72-hour window is critical because the effectiveness of PEP diminishes the longer the time since exposure. Therefore, starting treatment as soon as possible maximizes its potential to prevent HIV acquisition.

The other options do not provide a proactive approach to managing potential HIV exposure. Some involve waiting for symptoms to develop or do not recommend immediate treatment, contrary to guidelines emphasizing the importance of timely intervention to protect at-risk individuals. Monitoring and follow-up blood tests are indeed important components of post-exposure care, but they should be part of a comprehensive strategy that includes immediate PEP, rather than a substitute for it.
