HIV Risk Reduction

PEP (POST-exposure prophylaxis)

For a possible HIV exposure, call the Nurse Advice Line (512) 475-6877 (NURS) immediately to be evaluated for post-exposure prophylaxis (PEP). PEP is only effective within the first 72 hours after exposure.

The medical provider will assess your risk and determine if you would benefit from taking a three-drug regimen (one two-drug combo pill plus one other pill) for 28 days, called PEP. PEP is only effective if it is started within the first 72 hours after exposure.

PrEP (PRE-exposure prophylaxis)

A number of UHS healthcare providers prescribe Truvada or Descovy as pre-exposure prophylaxis to reduce the risk of getting HIV infection. This is a prevention option for people who are at risk of getting HIV. It is meant to be used consistently on an ongoing basis (one pill taken every day) and to be used with other prevention options such as condoms (United States Centers for Disease Control and Prevention).

If you are interested in making an appointment at UHS to discuss your risk factors with a healthcare provider to help you to determine if PrEP is right for you:

  1. Schedule a PrEP appointment by calling 512-471-4955. Let the scheduler know the reason for your visit so you are given the correct appointment type with a provider who prescribes PrEP.
  2. Print and review these forms prior to the appointment.

Bring these documents with you to your appointment to aid in the discussion with your provider about Truvada, its indications, its risks and its benefits. This appointment will last approximately one hour.
