What You Can Do

If you are a patient or parent

Use antibiotics only when a qualified professional prescribes them — never buy them over the counter for yourself or “save some for next time”.
Take them exactly as directed, and return unused antibiotics to a pharmacy rather than binning or flushing them.
Don't pressure your doctor for antibiotics; colds, flu, COVID-19 and most sore throats and sinus infections are viral, and antibiotics will not help.
Prevent infections in the first place: keep vaccinations up to date (including flu — it prevents the mistaken antibiotic courses that often follow), wash hands well, handle and cook food safely, and practise safer sex.
Never share antibiotics or use leftover ones — the wrong drug at the wrong dose is a resistance-training programme for your bacteria.

If you work in healthcare

Prescribe by guideline: right drug, right dose, right duration — and prefer narrow-spectrum “Access” antibiotics where possible.
Use diagnostics before (or alongside) empirical treatment, and de-escalate when results arrive.
Make infection prevention non-negotiable: hand hygiene, device care, isolation protocols and environmental cleaning stop superbugs moving between patients.
Support your institution's antimicrobial stewardship programme — audit, feedback and education demonstrably cut inappropriate use without harming outcomes.
Report resistance data to surveillance systems; the global picture is built from local labs.

If you farm or work with animals

Use antimicrobials only under veterinary oversight, to treat sick animals — not routinely to compensate for crowding, and never for growth promotion.
Invest in the alternatives that reduce the need: vaccination, hygiene and biosecurity, better housing and husbandry, and disease-resistant breeds.
Keep last-resort human antibiotics (such as colistin) out of animal use entirely.

If you influence policy or budgets

Fund the national AMR action plan — an unfunded plan is a press release, not a policy.
Invest in the unglamorous foundations: clean water and sanitation, vaccination programmes, laboratory capacity and surveillance.
Regulate: end over-the-counter antibiotic sales, enforce prescription rules, restrict farm use, and set discharge standards for pharmaceutical manufacturing waste.
Fix the market: support pull incentives (subscription models, market-entry rewards) so that developing a new antibiotic is not an act of commercial self-harm.
Mind the access gap: in much of the world, expanding access to effective antibiotics saves more lives than restricting it — stewardship and access must advance together.

Does individual action really matter?

Yes — arithmetic says so. Resistance rises with total selection pressure, and total pressure is the sum of billions of small decisions. Modelling in The Lancet suggests better infection care and wiser use of existing drugs could save 92 million lives by 2050 — more than four times what new drugs alone are projected to save. The most powerful tools against AMR are already in our hands.
