Narrator: This is Science Today. The state of California may become the first large state to issue guidelines for doctors about prescribing a little-known 'morning after' drug treatment for HIV exposure. Dr. Michelle Roland of the University of California, San Francisco has been studying the treatment called post-exposure prophylaxis, or PEP, since 1997.
Roland: So post-exposure prophylaxis generally refers to a 28-day course of two to three anti-HIV drugs that are taken within 72 hours of an exposure. This has been used in the healthcare worker setting following needle-sticks for many years.Narrator: Roland says there's no guarantee that the treatment will work, but results from animal and human studies point in the direction that it should.
