HIV PEP

• ~79% transmission reduction
• Initiate ASAP (goal = 1-2 hours)
• >36 hours: normally deferred, unless particularly high risk
• Common side-effects = constitutional, gastrointestinal

Specific Regimens (CDC)

1. Basic
   1. Exposures for which there is a recognized transmission risk
   2. 4 week, 2 drug regimen (normally zidovudine and lamivudine)
2. Expanded
   1. High risk exposures
   2. Basic regimen + protease inhibitor (e.g. indinavir or nelfinavir)

HIGH RISK

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
