Background

  • Also known as HIV Post-Exposure Prophylaxis (PEP)
  • ~79% transmission reduction
  • Initiate ASAP (goal = <2 hours after exposure)
  • >36 hours: normally deferred, unless particularly high risk
  • Common side-effects = constitutional, gastrointestinal

National Clinician's Post-Exposure Prophylaxis Hotline

  • 1-888-448-4911, call for expert advice

High Risk Exposures

Source

  1. Symptomatic HIV/AIDS
  2. Acute seroconversion
  3. High viral load

Exposure

  1. Deep injuries
  2. Visible blood on device
  3. Injuries sustained placing a catheter in a vein/artery

Workup (Before Giving)

  • CBC
  • C7
  • LFTs
  • Pregnancy test

Management

CDC no longer recommends that the severity of exposure be used to determine the number of drugs to be offered and a regimen containing 3 antiretroviral drugs is now recommended routinely for all occupational exposures.[1]

Negligible Risk

  • NOT recommended

Substantial Risk

  • CDC preferred regimen for 28 days:[2]
    • Raltegravir (isentress) 400 mg PO twice daily, plus
    • Truvada (tenofovir 300 mg + emtricitabine 200 mg) 1 PO once daily
  • If known source patient with resistant HIV strain, consult HIV service for source-patient-specific PEP
