Short answer
STI antibiotic resistance is the evolutionary bill for decades of underdosing and overtreatment: gonorrhea and M.
genitalium lead the retreat, surveillance maps it, and stewardship, complete prescribed courses, no self-treatment, clinician-directed adjustments, slows it.
Patients participate not by choosing drugs but by completing therapy, returning for follow-ups, and never improvising with leftover pills.

Gonorrhea has defeated sulfonamides, penicillins, tetracyclines, and fluoroquinolones in succession. Each loss forcing guidelines worldwide to rewrite around the survivors.
M.
genitalium shows widespread and rising macrolide resistance, which is why clinicians test for resistance markers before choosing therapy rather than repeating a drug that already failed elsewhere.
These histories explain a clinical behavior patients sometimes misread as indecision: when guidance changes, it is surveillance data arriving, not guesswork.
See Gonorrhea Testing: Samples and Accuracy for how susceptibility intelligence gets gathered.
Surveillance machinery that protects treatment
Programs such as the Gonococcal Isolate Surveillance Project culture and sequence samples from participating clinics, publishing susceptibility trends that drive regimen updates.
Treatment failures get cultured partly to feed this intelligence. Your follow-up visit contributes data protecting future patients.
Molecular assays increasingly detect known resistance mutations directly (for example, Mgen macrolide markers), rerouting therapy from failed drug classes before a dose is wasted.

Stewardship actions you control
Finish every prescribed course exactly as directed, never self-treat or share antibiotics, return for test-of-cure and cultures when advised, and accept stepped-up regimens without demanding stronger drugs casually.
Each completed appropriate course and each avoided improvisation slows resistance measurably. Individual adherence compounded across millions of patients is what keeps current drugs working.
Future directions without false promise
New antimicrobials sit in trials, gonorrhea vaccines show real research promise, point-of-care resistance assays are expanding, and experimental approaches continue. But none replaces stewardship of current drugs.
Promises of imminent post-antibiotic miracles should never delay today’s effective, guideline-based care.
When to seek care
For guideline-concordant first therapy, cultures with any treatment failure, and specialist referral for multidrug-resistant cases.
