What is PEP?
PEP stands for post-exposure prophylaxis. It involves taking anti-HIV medication as soon as possible (and no more than 72 hours or 3 days) after a potential exposure to HIV to help prevent infection.
Unlike PrEP, which is taken before potential exposure as an ongoing prevention method, PEP is for emergency use and is not designed for people who are regularly at risk of HIV.
How effective is PEP?
Research shows that PEP can reduce the risk of HIV transmission by more than 80% when taken correctly.
Who should consider PEP?
PEP may be recommended for people who, within the past 72 hours:
- May have been exposed to HIV through sex
- Shared contaminated needles or injecting equipment
- Were sexually assaulted
When should you take PEP?
PEP must be started as soon as possible – ideally within hours – after a potential exposure to HIV, and no later than 72 hours. The earlier it’s started, the more effective it is.
Once prescribed, PEP needs to be taken once daily for 28 days.
Where can you get PEP?
If you think you’ve been exposed to HIV, don’t wait for a GP appointment. Call the PEP Hotline on 1800 737 669 (1800 PEP NOW) to assess your risk, get guidance, and find a nearby location where PEP is available.
PEP is accessible at sexual health clinics and the Emergency Departments of most public hospitals.
Important things to know about PEP?
- It must be started within 72 hours of possible HIV exposure.
- It must be taken daily for 28 days.
- It does not protect against other sexually transmissible infections (STIs), such as Syphilis, Gonorrhoea, or Chlamydia.
If you believe you’re at ongoing risk of HIV, don’t wait for another emergency. Consider PrEP instead, as a long-term prevention option. Speak with your doctor or visit a Sexual Health Clinic to explore what’s right for you.
