For the clinical background on DoxyPEP — what it is, when to take it, the evidence, side effects, and the ongoing debate about antimicrobial resistance — see DoxyPEP: What It Is and Where It Stands first.

ASHM position (as of 2026): ASHM (Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine) has published guidance supporting DoxyPEP as an option for gay and bisexual men with a high burden of bacterial STIs. This places Australia ahead of some other jurisdictions in formally acknowledging the evidence. However, it is not yet on the PBS, and access is inconsistent across clinical services.

Where Things Stand

DoxyPEP is not yet part of the standard Medicare-funded pathway. There is no PBS listing. This means:

  • Some progressive sexual health centres and LGBTQ+ health services will prescribe it off-label — especially for patients with documented recurrent STIs on PrEP.
  • Access depends heavily on which clinic or prescriber you see.
  • Where it requires a private prescription, the cost is modest (doxycycline is cheap) but not zero.

Getting DoxyPEP

Step 1: Ask at Your Sexual Health Centre

Before doing anything else, ask your sexual health centre or sexual health doctor directly. Services like Sydney Sexual Health Centre, Melbourne Sexual Health Centre, Thorne Harbour Health, and ACON-linked services are the most likely to have a practical pathway for DoxyPEP.

The question to ask: "I'd like to discuss DoxyPEP. Is that something this service can prescribe?"

A good sexual health service will engage with this question seriously. They may prescribe it for you; they may not. If they decline, ask them to explain their current position — it may be a local policy position rather than a clinical one.

Step 2: LGBTQ+-Affirming GPs

Some GPs who specialise in gay men's health are willing to prescribe doxycycline for DoxyPEP purposes, particularly for patients with a documented pattern of STI recurrence despite consistent PrEP use.

The LGBTIQ+ Health Australia directory (lgbtiqhealth.org.au) lists affirming providers. When calling a new GP, ask: "Do you have experience prescribing DoxyPEP for gay men?"

Step 3: Telehealth Services

Some Australian online telehealth providers now offer explicit DoxyPEP consultations, understanding the clinical rationale and the ASHM position. Search for "DoxyPEP prescription Australia" — several legitimate services now advertise this pathway. Ensure the provider is AHPRA-registered (ahpra.gov.au to verify).

What You're Getting

Doxycycline 200mg, taken as a single dose within 72 hours of potential STI exposure. One dose covers one exposure event. For the evidence base, what it covers (chlamydia, gonorrhoea, syphilis) and what it doesn't (viral STIs, HIV), see the general guide.

Cost

When prescribed by a Medicare-bulk-billing service: potentially free.

When prescribed privately: doxycycline is generic and inexpensive. A course of 10 x 200mg doses typically costs $15–30 at a pharmacy, plus the consultation cost.

A Note on Antibiotic Stewardship

The ASHM guidance supporting DoxyPEP is carefully worded. The concern about antimicrobial resistance — particularly for gonorrhoea — is genuine and not a reason to dismiss. Australian clinicians are right to take this seriously.

If you use DoxyPEP, use it strategically: high-risk encounters, not reflexively after every sexual contact. Keep up your regular quarterly testing so that if resistance patterns emerge, they're detected quickly.

Do not share DoxyPEP doses with anyone who has symptoms. A 200mg dose is not a treatment for active gonorrhoea or syphilis. It will not cure an existing infection and will selectively favour resistant strains if misused.
