PrEP is a preventive strategy that uses antiretroviral medication in people who are HIV-negative to reduce the chance of acquiring HIV if they’re exposed. When taken as prescribed, it greatly lowers infection risk, especially with good adherence. It is not a treatment for someone who already has HIV, and it does not cure hepatitis B or prevent herpes simplex virus infections. Regular medical follow-up is important, including confirming HIV-negative status before starting and periodic testing, along with STI screening and kidney function checks.
