Post-Exposure Prophylaxis for HIV Exposure (PEP)

If you think you have had sex without a condom or have used or been stuck by a needle, you may have been exposed to HIV. Call us NOW or visit our Monroe Ave location to receive a medication (PEP) that can greatly reduce your likelihood of becoming infected with HIV.

To get PEP during business hours, call 585-454-PrEP (7737). For 24/7 PEP access, call 800-923-9394. It is important to call as soon as possible, as the medication should be taken as close to the time of exposure as possible.



  • PEP is for emergency use. If you think you are at prolonged risk for HIV, you should speak to a Trillium Health PrEP Specialist about starting PrEP
  • If you start PEP, you will need to:
    -Take the medicine for 30 days
    -Have a follow-up visit 30 and 60 days after you start PEP
  • PEP works best if it’s taken within 72 hours after a possible exposure


Potential Exposures to HIV:

  • Condomless and PrEP-less sex with a partner who is living with HIV or whose HIV status is unknown
  • Sharing syringes or needles
  • Accidental needle/syringe stick
