HIV Pre-Exposure Prophylaxis (PrEP) Explained
Daily and on-demand dosing, monitoring, and access pathways.
6 min read · Reference: CDC PrEP clinical guidelines
PrEP combines antiretroviral medications taken before potential HIV exposure to prevent acquisition. Daily oral tenofovir/emtricitabine is standard; on-demand protocols exist in some regions for men who have sex with men.
Baseline and periodic HIV testing, kidney function labs, and STI screening accompany prescribing. PrEP does not replace condoms for other STIs.
Cost and insurance coverage vary; patient assistance programs exist. Pharmacists in some locales can initiate or continue PrEP.
If exposure occurs without PrEP, post-exposure prophylaxis (PEP) must begin within 72 hours—often via emergency departments.
