The World Health Organisation calls it one of the top ten threats to global public health. Each year, antibiotic resistance is linked to over a million deaths worldwide. And yet for most patients, it remains an abstract concept — until they or a family member actually need an antibiotic that no longer works.
Here's the encouraging part: while the trend is serious, it's also addressable. The actions of individual patients, prescribers, and pharmacists genuinely matter. This article explains what's happening, why it matters to you, and the practical things every patient can do.
What antibiotic resistance actually is
Antibiotics are medicines that kill bacteria or stop them growing. They've been one of the most transformative inventions in medical history — without them, surgery, chemotherapy, and even childbirth would be far more dangerous.
Resistance happens when bacteria evolve to survive the antibiotic that used to kill them. It's not the patient who becomes resistant; it's the bacteria. And once a bacterial population becomes resistant, the same illness in someone else may also fail to respond to the same drug.
This is why resistance is a community-wide problem, not an individual one. Every unnecessary or incorrectly-taken course of antibiotics gives resistant bacteria a survival advantage.
Why it's getting worse
Three things drive rising resistance:
- Over-prescription — antibiotics prescribed when they aren't clinically needed (e.g. for viral illnesses).
- Incomplete courses — patients stopping antibiotics early when they feel better, leaving partially-resistant bacteria behind.
- Agricultural use — antibiotics used as growth promoters or prophylactically in livestock farming, with resistant bacteria entering the food chain and water supply.
The first two are within reach of clinicians and patients. The third is a policy issue, but the UK has already implemented restrictions in line with WHO recommendations.
Why the GP queue isn't always the right answer
Before NHS Pharmacy First launched in 2024, patients with bacterial infections (sinusitis, sore throat, UTI in young women, infected insect bites, impetigo, shingles, earache) typically had to wait days for a GP appointment to get assessed and, where appropriate, prescribed antibiotics.
That delay had two costs:
- Patients getting worse while they waited.
- Pressure on GPs to prescribe quickly during an appointment, sometimes for marginal cases.
Pharmacy First shifts this model. Pharmacists are now trained to assess and treat seven specific conditions clinically — meaning antibiotics are dispensed where genuinely indicated, and not where they aren't. Same-day access reduces the pressure to "just prescribe" that drives over-prescription.
Five things every patient can do
These aren't dramatic. Steady patient behaviour, multiplied across millions of consultations, is exactly what reverses the trend.
- Don't ask for antibiotics if you don't need them. Most coughs, colds, and sore throats are viral. Ask "is this likely viral?" and trust the answer.
- If you're prescribed antibiotics, finish the full course — even if you feel better halfway through. Stopping early leaves the most resistant bacteria alive.
- Don't share antibiotics or use leftover ones. A drug that worked for a UTI may be wrong for an ear infection. Different bacteria, different drugs.
- Take them on time. Skipping doses or spacing them irregularly gives bacteria a chance to recover and develop resistance.
- Get vaccinated. Vaccines prevent illnesses that might otherwise need antibiotics. Flu and pneumococcal vaccines are particularly relevant.
When antibiotics are absolutely the right call
Most antibiotic prescriptions in the UK are clinically appropriate — and patients should take them with full confidence. Antibiotics are the right answer for:
- Bacterial pneumonia and severe chest infections
- Bacterial skin infections (cellulitis, infected wounds)
- Confirmed UTIs
- Bacterial meningitis (life-saving)
- Strep throat (when clinically indicated)
- Sepsis
- Many post-surgical infections
The point is not to avoid antibiotics — it's to use them carefully and only when they actually help. Pharmacists like our team at Qrystal are trained to make exactly this distinction, and Pharmacy First gives us the formal authority to prescribe where clinically right.
When you've started a new antibiotic
If you've recently been prescribed an antibiotic and have any concerns — about side effects, dose timing, interactions with your other medications, or whether to continue — the free New Medicine Service is designed for exactly this. Two free pharmacist consultations, no GP referral needed.
Antibiotic resistance isn't unstoppable. The choices we all make — patients, prescribers, pharmacists, policymakers — directly determine how the next 20 years play out. Most patients want to do the right thing. The information above is what doing the right thing looks like in practice.
