PrEP dosing across time zones, STI tests, doxy-PEP, the right vaccines and where to find PEP fast: a practical sexual-health checklist for queer travellers.
Sexual health when travelling sounds like a buzzkill, but it is really just smart packing. If you plan to have sex on your trip, a little prep makes everything more relaxed: PrEP in your bag, a plan for an STI test back home, the right vaccines, and the peace of mind of knowing where to turn if something goes wrong. Here is what to sort out before you leave and what to keep in mind on the road.
PrEP on the move
If you take PrEP, plan your trip around your dosing. On daily PrEP, pack enough pills for the whole trip plus a small buffer in case your return gets delayed. Keep them in their original packaging and stash them in your carry-on, so a lost suitcase never leaves you short.
- On-demand PrEP (2-1-1): Some people use event-driven dosing instead of daily pills. Talk to your doctor before you go to see whether it fits your trip and your sex life.
- Time zones: When you cross several zones, either shift your daily dose gradually or simply keep taking it on home time. A fixed phone alarm makes this easy.
- Proof: A prescription or a short note from your doctor saves you any hassle if your pills draw questions at customs.
Do not count on buying PrEP on the spot at your destination. Availability, price, and prescription rules vary a lot from country to country. Our overview of where and how to get PrEP worldwide is a good starting point, and there is a separate guide to carrying PrEP and HIV medication through customs if you are crossing trickier borders.
STI testing around your trip
Testing right before you fly is rarely practical, but a check a few weeks after you get back makes a lot of sense. Many infections only show up reliably after a window period, so a little patience pays off. The easiest move is to book the appointment while you pack.
Testing abroad is possible but not always simple. A European health card usually does not cover preventive services like routine screening, so you may pay out of pocket as a private patient. In many countries, though, sexual health checkpoints and queer health organisations offer anonymous and often free testing, regardless of your insurance status.
Doxy-PEP: the newer piece of the puzzle
Beyond HIV, a growing number of clinics now discuss doxy-PEP, a single 200 mg dose of doxycycline taken after condomless sex to lower the risk of bacterial STIs. Trials have shown solid drops in syphilis and chlamydia and a smaller effect on gonorrhoea. It works best taken within 24 hours and no later than 72 hours after the encounter.
This is not a packing item for everyone. Several health authorities suggest it mainly for gay and bisexual men who have had a bacterial STI in the past year, and it is meant to sit alongside regular screening rather than replace it. If it sounds relevant to how you travel, raise it at your pre-trip appointment so you know whether to carry a small supply.
Vaccines worth thinking about
A handful of vaccines protect against infections that also spread through sex. They belong in any good pre-travel chat, especially if your trip involves a busy scene or sex parties.
- Hepatitis A and B: Both can be passed on sexually and come as a combined vaccine given in several doses. Start early, since full protection takes weeks to build.
- Mpox: Many countries recommend the vaccine for gay and bisexual men and other men who have sex with men, particularly with new or multiple partners.
- HPV: If you have not been vaccinated yet, the HPV vaccine is worth discussing anyway, trip or no trip.
Timing is the catch. Some of these schedules run over weeks or months, so an appointment a couple of months out beats a panicked one the week before departure.
Condoms and safer sex
Bring condoms and lube from home. Quality, availability, and price are unpredictable at your destination, and some sizes or oil-free lubricants can be hard to find. A small stash in your toiletry bag takes almost no space and saves you the search.
Remember that PrEP protects against HIV but not against other infections. Condoms stay a sensible part of the mix, especially with new partners. What works for you is your call, depending on the situation and the risk you are comfortable with. If your trip leans into saunas or cruising, the same logic carries over to cruising while travelling and a first visit to a gay sauna.
Finding help on the ground
If something does happen, knowing in advance where to go makes a real difference. Before you leave, check whether your destination has queer health services, checkpoints, or HIV organisations, and save the addresses.
PEP matters most here, the emergency treatment after a possible HIV exposure. It has to start within 72 hours, and the sooner the better, then runs as a 28-day course. If you already know which clinic or emergency room at your destination provides PEP, you will not lose precious time when it counts. For the wider picture, our emergency guide for travellers covers who to call and what your rights are when things go sideways abroad.
