Overview

A urinary tract infection is bacteria multiplying where there should be none. Around 80% are caused by E. coli from the bowel reaching the urethra.

Women get them far more often than men — roughly one in two women will have at least one — for the straightforward anatomical reason that the female urethra is short, so bacteria have a much shorter distance to travel.

Most uncomplicated bladder infections in otherwise healthy women respond to a three-day course of antibiotics, and this is one of the conditions where the value of same-day access is not convenience but symptom relief — an untreated UTI is genuinely miserable and waiting a week for an appointment is a poor experience of healthcare.

Two things on this page matter more than the treatment itself. A UTI in a man is never routine and needs a different approach. And visible blood in the urine needs investigating even after the infection clears — that is the single most important sentence here, and the one most often missed.

Common symptoms

Bladder infection — the usual picture

  • Burning or stinging when passing urine
  • Needing to go far more often, and urgently
  • Passing only small amounts despite the urge
  • Pain or pressure low in the abdomen
  • Cloudy, strong-smelling urine
  • Blood in the urine — common with infection, and always worth reporting
  • Feeling generally off, without a high fever

Kidney infection — a different and more serious problem

Bacteria travelling up to the kidney produces a distinctly different illness:

  • Pain in the back or side, below the ribs, usually on one side
  • Fever, shivering and rigors
  • Nausea and vomiting
  • Feeling genuinely unwell rather than uncomfortable

This needs a different antibiotic, a longer course, and sometimes hospital treatment.

Older adults — and an important caution

In frail older people a UTI can present as sudden confusion, falls or reduced mobility with none of the classic symptoms.

But the opposite error is at least as common. Bacteria are present in the urine of a large proportion of healthy older people without causing any illness — asymptomatic bacteriuria — and treating that with antibiotics does not help and causes harm. Confusion in an older person has many causes, and a positive urine dipstick is not proof that a UTI is responsible. Dipsticks are unreliable over 65 and current guidance is not to use them in that age group.

Causes and risk factors

  • Female anatomy — a short urethra sitting close to the anus
  • Sexual activity, which mechanically introduces bacteria. This is the commonest identifiable trigger in younger women, and it is not a reflection of hygiene
  • The menopause. Falling oestrogen thins the vaginal and urethral tissue and alters the protective bacterial population, which is why UTIs become much more frequent after 50. This cause is both extremely common and very treatable
  • Incomplete bladder emptying — from prostate enlargement in men, prolapse in women, or a neurological condition
  • Diabetes, particularly when poorly controlled
  • Urinary catheters, which almost always lead to bacteria in the urine
  • Kidney stones
  • Constipation, which is a genuinely underestimated contributor, especially in children
  • Pregnancy, where hormonal and mechanical changes slow urine flow

Things widely blamed that matter less than you would think

Baths, underwear choice, and not drinking enough are all frequently cited. Fluid intake does have some evidence behind it; the others have very little. Nothing about a UTI reflects poor hygiene, and being told otherwise is both wrong and unhelpful.

How it is diagnosed

In a woman under 65 with typical symptoms and no complicating factors, the diagnosis is made on symptoms alone and treatment can begin immediately. Burning, frequency and urgency together, with no vaginal discharge or irritation, gives a high probability of infection — high enough to treat.

Urine dipstick

Useful in women under 65 where the picture is unclear. Nitrites are the more meaningful finding; leucocytes alone are much less specific. Dipsticks should not be used in the over-65s, where they are positive so often in the absence of infection that they mislead more than they help.

Urine culture — when it is genuinely needed

A sample sent to the laboratory identifies the exact organism and which antibiotics will work. It is important, rather than optional, in:

  • Men — always
  • Pregnancy — always, including where there are no symptoms
  • Recurrent infections
  • Treatment failure, or symptoms returning immediately after a course
  • Suspected kidney infection
  • Children

When to look further than the bladder

  • Any UTI in a man warrants thought about the prostate, incomplete emptying or a structural cause — it is not simply the female illness in a male patient
  • Recurrent infection may need imaging to look for stones or retained urine
  • HbA1c, since recurrent UTI is a recognised way undiagnosed diabetes presents
  • Kidney function, which also determines whether nitrofurantoin is safe to use

What imitates a UTI

Thrush and bacterial vaginosis cause external stinging that is easily mistaken for cystitis — the distinguishing feature is vaginal discharge or itch. Chlamydia and gonorrhoea cause urethritis with very similar symptoms, and are missed when everyone assumes UTI. Interstitial cystitis produces identical symptoms with repeatedly negative cultures.

How we treat it online

Uncomplicated UTI is among the best uses of a same-day remote appointment. The diagnosis rests on the history, and treatment can be with your pharmacy within minutes of the consultation ending.

How the pathway works

Treated online first, reassessed in person if it does not settle. That is the sequence, and it is worth stating plainly because it is how most UTIs are safely managed.

  • We treat on the history, same day
  • You tell us if it has not improved within 48 hours, or sooner if you become more unwell
  • No improvement means reassessment — a urine culture to guide a different antibiotic, and in-person assessment where the picture has changed

Failing to improve is information, not a setback. It usually means resistance rather than anything sinister, and it changes the antibiotic rather than the diagnosis.

Antibiotic treatment

  • Nitrofurantoin is usually first choice — typically three days for a woman, seven for a man. It concentrates in the urine, which is exactly where it is needed. Two things matter: it requires reasonable kidney function, so we check or ask about that; and it does not work for kidney infection, because it does not reach the kidney tissue itself
  • Trimethoprim as an alternative, though local resistance is now substantial
  • Longer courses for men, for kidney infection, and where response is slow

Pregnancy

UTIs in pregnancy are always treated, including when there are no symptoms, because of the risk of kidney infection and preterm labour. Antibiotic choice is specific: trimethoprim is avoided in the first trimester, and nitrofurantoin is avoided near term. Always tell us if you are or might be pregnant.

Recurrent UTI — what actually helps

Three or more infections a year is worth treating as a problem in its own right rather than as a series of separate events.

  • Vaginal oestrogen for postmenopausal women. This has good evidence, substantially reduces recurrence, and is markedly underused. It is a local treatment, absorbed minimally, and suitable for many women who cannot take systemic HRT
  • Post-coital antibiotic prophylaxis — a single dose after sex, where infections are clearly sexually related. More effective and far lower total antibiotic exposure than continuous treatment
  • Standby antibiotics — a supply held at home to start at the first symptom, appropriate for some people
  • Reviewing constipation, bladder emptying and contraception — spermicides and diaphragms both raise risk
  • D-mannose and cranberry: the evidence is weak. Neither is harmful, and if they help you, continue — but they are not a substitute for treatment and we will not pretend otherwise

The limits of remote care

We cannot dipstick your urine or take a sample. Where culture is needed we arrange it. Suspected kidney infection, pregnancy with fever, or anyone systemically unwell needs in-person assessment from the outset, and we will direct you there rather than prescribing and hoping.

Important

When to seek urgent help

Call 999 or go to A&E if you have urinary symptoms with:

  • Confusion, drowsiness or slurred speech
  • Shivering uncontrollably, or feeling very cold with a high temperature
  • A racing heart, breathing quickly, or feeling you might pass out
  • Not passing urine at all for many hours
  • Severe pain

These are signs of sepsis, which can develop from a urinary infection and progresses quickly.

Seek same-day assessment for:

  • Fever, shivering, or pain in your back or side — suggesting kidney infection
  • Vomiting, or being unable to keep tablets down
  • Any urinary symptoms in pregnancy
  • Symptoms not improving 48 hours after starting antibiotics
  • A UTI in a child, or in a man with fever
  • Symptoms in anyone with a catheter, a single kidney, a transplant, or a weakened immune system

The one that gets missed

Visible blood in the urine must be investigated even after the infection has been treated. If you are over 45 and have had visible blood in your urine — with or without an infection — that requires urgent urology referral to exclude bladder cancer. Being told it was "just a UTI" is not a reason to leave it, and we will arrange that referral.

Prevention and self-care

While you have symptoms

  • Drink more fluid — water rather than anything else. This has reasonable evidence for both treating and preventing infection
  • Paracetamol or ibuprofen for the pain, which is often underused
  • Alkalinising sachets from the pharmacy should not be used with nitrofurantoin, because they reduce how well it works. Check before combining them
  • Avoid caffeine, alcohol and fizzy drinks while symptomatic — all irritate an inflamed bladder
  • Symptoms should improve within 48 hours of starting antibiotics. If they are not improving, or you are getting worse, that needs reviewing rather than waiting out the course

Reducing recurrence

  • Do not hold urine. Go when you need to, and take time to empty completely — waiting a few seconds and trying again empties the bladder more fully than most people manage in a hurry
  • Pass urine soon after sex. Simple, free, and the measure with the most consistent support for sexually-related infections
  • Wipe front to back
  • Treat constipation, which is a genuine and frequently overlooked contributor
  • Avoid spermicides and diaphragms if UTIs are recurrent — an alternative contraceptive may resolve the problem entirely
  • Stop using soaps, bubble bath and feminine washes on the genital area. These strip the protective bacteria and irritate the urethra. Plain water only
  • If you are postmenopausal, ask specifically about vaginal oestrogen. It is the single most effective preventive measure in that group and is rarely offered unprompted

NHS or private

Pharmacy First now treats uncomplicated UTI in women aged 16 to 64 free, same day, without an appointment. That is genuinely the best route for a straightforward UTI in England, and we would point you there before charging you.

Your NHS GP treats UTIs free, and nitrofurantoin and trimethoprim are very cheap generics.

What is worth knowing and costs nothing: a proportion of uncomplicated UTIs settle without antibiotics, and delayed prescribing is a recognised approach in mild cases. Fluids and paracetamol are reasonable first steps.

Where money is wasted: cranberry products and alkalinising sachets, both of which have weak evidence for treating an established infection.

Where a private consultation genuinely earns its fee is recurrent UTI, which is a different problem from a single episode and is frequently managed badly — repeated short antibiotic courses without a plan. The options that actually help are under-offered: vaginal oestrogen in postmenopausal women, which substantially reduces recurrence and is not systemic HRT; methenamine hippurate, which NICE now supports as a non-antibiotic option; and where appropriate, standby or prophylactic regimens.

Sending a urine sample matters more than people think in recurrent infection, since resistance is common and treatment is otherwise guesswork.

What needs urgent care: fever, loin pain, vomiting, confusion — particularly in older people, where confusion may be the only sign. Blood in the urine that persists after treatment needs investigating.

Evidence and guidelines

NICE NG109, Urinary tract infection (lower): antimicrobial prescribing, is the governing guideline. It recommends nitrofurantoin or trimethoprim first-line for non-pregnant women, with a three-day course, and considering back-up prescribing where symptoms are mild.

NG109 recommends a urine culture in pregnancy, in men, in recurrent infection, and where treatment has failed.

NICE NG112, Urinary tract infection (recurrent): antimicrobial prescribing, covers prophylaxis and recommends vaginal oestrogen for postmenopausal women with recurrent UTI, and behavioural and personal hygiene measures.

NICE has since supported methenamine hippurate as a non-antibiotic option for preventing recurrent UTI, following the ALTAR trial.

NICE NG111 and NG113 cover pyelonephritis and catheter-associated infection, and NICE NG12 covers visible haematuria as a criterion for urgent urological referral.

Common questions

Do I definitely need antibiotics?

Not always. A proportion of mild bladder infections settle on fluids and pain relief alone, and delayed prescribing — holding a prescription for 48 hours to see whether things improve — is a reasonable option for mild symptoms in an otherwise healthy woman. But this is a genuine bacterial infection, symptoms are unpleasant, and there is a real risk of it ascending to the kidney, so treatment is usually the right call.

Why do I keep getting them?

Most often for a specific and identifiable reason: sexual activity, the menopause, incomplete bladder emptying, constipation, or a contraceptive method. Recurrent UTI is a problem to solve rather than a run of bad luck, and the solution frequently is not more antibiotics — vaginal oestrogen after the menopause, or a change of contraception, resolves a great many.

Does cranberry juice work?

The evidence is weak and inconsistent. Cranberry capsules or D-mannose are unlikely to do harm, and if you find they help then there is no reason to stop. They are not a treatment for an established infection.

Can I get antibiotics without being tested?

In a woman under 65 with clear, typical symptoms and nothing complicating the picture, yes — that is standard practice and it is what current guidance recommends. Men, pregnant women, children, recurrent cases and treatment failures should all have a urine sample cultured.

Is a UTI sexually transmitted?

No. Sex can trigger one by moving your own bowel bacteria to the urethra, but nothing is being passed from a partner and partners do not need treatment. That said, chlamydia and gonorrhoea cause very similar symptoms, so where there is any risk of exposure, testing for those is sensible.

Why does my urine test keep coming back negative when I feel awful?

Persistent bladder symptoms with repeatedly negative cultures may be interstitial cystitis, a non-infective inflammatory condition of the bladder that is often mistaken for recurrent UTI for years. It needs a different approach entirely, and repeated antibiotics will not help.

Should my partner be treated?

No, unless they have symptoms themselves. UTIs are not passed between partners.

I'm caring for an older relative who seems confused — is it a UTI?

Possibly, but treat that assumption with caution. Bacteria in the urine are extremely common in older people without causing illness, and a positive dipstick does not prove a UTI is behind the confusion. New confusion in an older person needs a proper assessment for all its possible causes — not simply a course of antibiotics.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
