Post-Exposure Prophylaxis

What is PEP?

What is it?

PEP

PEP (Post-Exposure Prophylaxis) is an emergency treatment that reduces the chances of contracting HIV infection and can be taken AFTER a potentially risky exposure.

What does it include?

PEP involves taking antiretroviral drugs for 28 consecutive days. It is an emergency treatment because it is more effective if started early. It is optimal to take the first dose of the drug within 24 hours of exposure, but it is no longer recommended after more than 72 hours.

When is it useful?

Situations in which the use of PEP is evaluated are, for example:
  • unprotected sexual intercourse with a person of unknown serostatus or with known HIV infection and detectable/unknown viremia
  • exchange of material for the preparation and/or injection of intravenous substances
  • puncture with a hollow needle or percutaneous lesion with a needle and/or sharp material

Does it cost to do PEP?

PEP is free. It is an extraordinary measure, designed for emergency situations and not for routine use. In cases of potentially risky exposures that occur repeatedly, there are other strategies that can reduce the risk of contracting the infection, including PrEP (Pre-Exposure Prophylaxis).
