Health care providers nationwide can now call a consultation service to get expert information about pre-exposure prophylaxis, or PrEP, which currently entails prescribing the daily pill Truvada to prevent HIV infection in adults at high risk.

The PrEPline is run by the University of California, San Francisco’s Clinician Consultation Center (CCC) at San Francisco General Hospital and Trauma Center. The U.S. Centers for Disease Control and Prevention awarded a $175,000 grant for the PrEPline’s first year.

“Many of the clinicians prescribing PrEP will have had limited experience prescribing antiretroviral drugs,” said CCC director Ron Goldschmidt, MD, in a press release. “We will guide these clinicians as they work through decisions about who might benefit from PrEP and for whom it’s not advisable to prescribe PrEP, how to provide follow-up to ensure safe medication use, and protocols for averting and identifying new transmissions.”

The PrEPline joins a host of HIV-related consultation services the CCC provides to clinicians.
