PrEP

What is PrEP?

  • PrEP = Pre-Exposure Prophylaxis: Medication that helps HIV-negative people prevent HIV transmission through sex or injection drug use.
  • Effectiveness: Up to 99% effective when used consistently.
  • Monitoring: Requires quarterly HIV and blood tests to check kidney/liver health (for oral PrEP) or before injections.

  • You’re unsure of your partner(s)’ HIV status
  • You use alcohol or other drugs during sex
  • You are in a relationship with an HIV-positive partner who isn’t yet undetectable
