Because Centers for Disease Control and Prevention (CDC) guidelines recommend HIV-1 testing every 3 months while receiving PrEP, patients should not be prescribed PrEP for more than 90 days at a time. It is important to test patients on PrEP every 90 days to document continued HIV-negative status. If HIV infection occurs while patients are still taking PrEP, they are at risk of developing drug resistance. Other laboratory tests, including renal function and STI testing, are also recommended periodically.
