STI prevention, taken within a 72-hour window.
A short clinical consultation, reviewed by UK-registered clinicians, leading to a personalised prevention plan you take within 72 hours of condomless sex. It significantly reduces the risk of bacterial STIs — particularly chlamydia and syphilis — and is part of current UK clinical guidance for people at higher risk.
You're not the first person to think about this after a Friday night.
Most people who come to us for a prevention consultation aren't reckless. They're informed, sexually active adults who know condoms aren't always used, and want a clinically-backed option for the windows when they aren't. Here's what we hear most.
The Sunday-morning panic
You're not sure if you were safe. The earliest you can get a useful STI test is two weeks away. The waiting is awful and the not-knowing is worse.
"A post-exposure prevention plan exists for exactly this window — taken within 72 hours."
GUM clinics that take three weeks to call back
NHS sexual health services are excellent but stretched. By the time you get an appointment, the 72-hour window is long gone.
"A private consultation gets you a clinical decision within the window when prevention is still possible."
Tired of antibiotic rounds after positive tests
If you've had chlamydia or syphilis once, the treatment isn't fun and the partner-tracing conversations are worse. Prevention is calmer than cure.
"Clinical evidence suggests significant reduction in these infections for people at higher exposure risk."
Already on PrEP, still worried about STIs
PrEP is brilliant for HIV. It doesn't do anything for chlamydia, syphilis, or gonorrhoea. A bacterial-STI prevention plan is the counterpart.
"Many of our patients pair this prevention plan with their existing PrEP — the two work alongside each other."
What the prevention plan involves.
It's a single, clinician-prescribed dose you take within 72 hours of condomless sex. The earlier the better — within 24 hours is ideal. The consultation checks your medical history, looks for anything that would make it unsafe for you, and confirms eligibility against current UK guidance.
When suitable, the plan significantly reduces the risk of bacterial STIs — particularly chlamydia and syphilis, with a smaller effect on gonorrhoea. It does not protect against HIV, herpes, HPV, hepatitis, or other viral infections.

The numbers, plainly.
Two large randomised clinical trials, plus follow-up real-world data, have produced the figures below. UK BASHH issued an interim position statement in 2024 supporting post-exposure prevention for men who have sex with men and trans women with recurrent bacterial STIs.
Sources: BASHH Interim Position Statement on bacterial STI post-exposure prophylaxis (2024); Luetkemeyer et al., NEJM 2023; Molina et al., Lancet ID 2023. Numbers vary by study population and STI type.
It's not for everyone. Here's the honest split.
Every consultation is assessed against current UK clinical guidance. If it's not suitable, you'll be told why and refunded. That's the point of a real prescriber, not a vending machine.
Generally suitable
- Men who have sex with men, trans women, and non-binary people in similar contexts
- Already on PrEP and wanting bacterial-STI cover too
- People with a history of recurrent chlamydia or syphilis
- Sex workers and others with frequent condomless exposure
- People in open or polyamorous relationships
- Anyone over 18 with a recent condomless exposure who wants the option
Probably not suitable (we'll flag)
- Tetracycline-class allergies
- Pregnancy or trying to conceive
- Severe liver impairment
- Certain interacting medications — flagged at consultation
- Under 18
- Frequent / daily use — this is a targeted prevention plan, not daily prophylaxis
How this stacks up against the alternatives.
No prevention method is perfect on its own — and we'll never tell you otherwise. Most patients pair a post-exposure prevention plan with PrEP, condoms when practical, and regular testing. Here's how the options compare.
Being honest about the limits.
Selling something properly means saying what it doesn't do, too. This prevention plan works inside a specific window, against specific infections, when used responsibly. It's not a magic shield.
Not a replacement for condoms.
Condoms remain the only single-method protection against HIV, HPV, and herpes. This plan works alongside them, not instead.
Not a replacement for PrEP.
If HIV is a concern, you need PrEP. This plan only addresses bacterial STIs. The two combine well.
Not a replacement for testing.
Regular STI testing (every 3–6 months for sexually active people) matters whether or not you use this plan. We can advise on options.
Not for daily use.
This is taken after exposure, not as a daily preventive. Daily use raises antibiotic resistance concerns and isn't supported by current evidence.
Not 100% effective.
Trial data suggests roughly 70% reduction for chlamydia and syphilis, less for gonorrhoea. It significantly lowers risk; it doesn't eliminate it.
Not for everyone.
Pregnancy, certain allergies, and certain interacting medications rule it out. The consultation catches this — you'll be told and refunded.

FAQs.
Is this prevention plan legal in the UK?
Yes. The treatment used is a long-established, UK-licensed antibiotic class with decades of safety data. Its application for post-exposure STI prevention is off-label — meaning the original product licence covers treatment of bacterial infections rather than prevention — but off-label prescribing is normal clinical practice when supported by evidence. UK BASHH issued an interim position statement in 2024 supporting post-exposure prevention for higher-risk MSM and trans women.
How effective is it really?
Randomised trials in MSM and trans women showed roughly 70% reduction in chlamydia and syphilis, and around 50% reduction in gonorrhoea (lower because of higher tetracycline resistance). Effectiveness depends on starting the plan within 72 hours of exposure — sooner is better. It's not a guarantee; it's a significant reduction in risk.
Can I use this with PrEP?
Yes — this prevention plan and PrEP are commonly used together. PrEP covers HIV, this plan covers most bacterial STIs. There are no significant interactions between them. Many patients using this consultation are also on PrEP.
What about antibiotic resistance?
It's a legitimate concern and we don't dismiss it. The plan is targeted (used after exposure, not daily), reviewed by a clinician for appropriateness, and most useful for people who would otherwise need repeated treatments for actual infections. The current clinical consensus is that the individual resistance risk is outweighed by the prevention benefit when used in eligible groups — but it's actively discussed in every consultation.
What are the side effects?
The most common are mild nausea and increased sun sensitivity. Taking the dose with food and water reduces nausea. Use sunscreen if you're spending time outdoors. Less common: indigestion, oesophageal irritation if taken without enough water. Severe reactions are rare and listed in the patient information leaflet that comes with your prescription.
Can I use it every time I have sex?
The evidence supports use after condomless exposure — not daily, and not "prophylactically before" sex. Frequent use needs a clinical conversation: if you'd use it more than ~3 times a week, we'll usually want to talk through whether a different approach (or more frequent testing) makes sense.
How discreet is delivery?
Plain outer packaging, no pharmacy branding or product information visible on the outside. Standard Royal Mail Tracked 24. If you'd prefer to collect from a pickup point, that can be arranged at checkout.
What if I'm declined?
About 1 in 6 consultations aren't suitable — usually due to allergies, interacting medications, or specific medical history. If declined, you've paid nothing, and a clinician will tell you why. If there's an obvious alternative we'll point to it.
How do I cancel or stop?
There's nothing to cancel — you buy what you need, when you need it. No subscription, no minimum term, no recurring charges. Order a 15-treatment plan now, use them over six months, order more whenever.
Will my GP know?
Only if you ask us to share with them. Private prescriptions stay between you and our pharmacy unless you opt in to update your NHS record. We can integrate with the NHS Summary Care Record if you'd prefer — your choice.
