DoxyPEP — taking doxycycline within 72 hours of condomless sex to reduce STI risk — is not yet a formally endorsed part of Croatian sexual health guidelines. But it is accessible via the right doctor, and worth knowing about if you're having frequent STI recurrences.
What DoxyPEP Does
A single 200mg dose of doxycycline taken within 72 hours (sooner is better) after condomless sex reduces the risk of chlamydia and syphilis by approximately 70–80%, and gonorrhoea to a lesser extent. It doesn't replace testing, and it doesn't protect against HIV. It's a complementary tool, particularly useful if you're on PrEP and already getting regular testing.
See the DoxyPEP General Guide for the full evidence base.
Access in Croatia
DoxyPEP is not part of any official Croatian programme, but doxycycline is a generic antibiotic available on prescription. Getting it requires a doctor willing to prescribe it for this use.
Best route: UHID infectious disease specialist Klinika za infektivne bolesti "Dr. Fran Mihaljević" Mihaljevićeva 14, Zagreb
If you're already established as a PrEP patient at UHID, your infektolog is the best person to have this conversation with. They understand the evidence, work in sexual health, and can write a private prescription (privatni recept) for doxycycline. Be direct: ask whether they'd consider prescribing doxycycline for post-exposure STI prophylaxis given your profile.
CheckPoint Zagreb as a navigation point: If you're not yet a UHID patient or aren't sure how to raise this, CheckPoint Zagreb (huhiv.hr) can advise on which doctors are open to this conversation and how to approach it.
Private GPs with sexual health experience: Some private GPs in Zagreb who work with gay and bisexual men may also be willing to prescribe. Iskorak (iskorak.hr) may have referrals.
Cost
Doxycycline is a cheap generic antibiotic. A course of DoxyPEP (a single dose per sexual encounter, taken episodically) costs very little per use:
- A pack of doxycycline 100mg tablets (enough for multiple doses) typically costs €3–8 in a Croatian ljekarna (pharmacy)
- The main cost is the private prescription consultation if you're going that route
What to Say to Your Doctor
"Nisam u formalnom programu, ali zanima me doksiciklin za postekspozicijsku profilaksu SPB-a. Ima li mogućnost privatnog recepta?" (I'm not in a formal programme, but I'm interested in doxycycline for post-exposure STI prophylaxis. Is a private prescription possible?)
In English, with an English-speaking doctor: simply ask about doxycycline post-exposure prophylaxis for STIs — any infectious disease specialist will understand immediately.
Important Context
DoxyPEP is not a substitute for testing. If you're using it, you should still be getting regular full STI panels — throat, rectal, and urethral swabs — every three months or after higher-risk periods. Asymptomatic STIs are common, and DoxyPEP doesn't guarantee prevention.
Antibiotic resistance is a real concern. This is why DoxyPEP is recommended as a targeted strategy for people with frequent STI exposure — not as routine prevention for everyone. Use it thoughtfully.
HIV: DoxyPEP does nothing for HIV. For HIV, PrEP is your primary tool. For HIV PEP after a specific exposure, see PEP Emergency in Croatia.
