Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. A bladder infection in a woman who is not pregnant is treated by video; men, pregnancy, catheters and signs of a kidney infection need a urine test in person first.
- Early signs: burning or stinging when you pee, needing to pee more often, including at night, and cloudy urine; in women under 65 these 3 signs are what doctors rely on most.
- Men: bladder infections are less common in men, always need a urine culture before antibiotics, and can involve the prostate.
- Over 65: urine dipsticks are not used, because bacteria in the urine without symptoms are common and treating them does not help.
- Emergency: call 112 for confusion, slurred speech, very fast breathing, blue, grey, pale or blotchy skin, or no longer passing urine.
Do not book a video appointment if you or the person you care for has sudden confusion or slurred speech, very fast breathing, blue, grey, pale or blotchy skin, a rash that does not fade when pressed, or has stopped passing urine: call 112. A high temperature with back or side pain, or a bladder infection in a man, in pregnancy or with a catheter, needs an in-person assessment with a urine test.
Can an online doctor treat a bladder infection?
Yes, usually. Most bladder infections are in women, and in a woman who is not pregnant a doctor can recognise one from typical symptoms by video and prescribe a short antibiotic course when it is needed. Bladder infections in men, in pregnancy, with a catheter, in an older person with new confusion, and with a high temperature or back pain are treated as complicated: they need a urine culture or an examination in person, and the doctor tells you where to go and how quickly.

How an online consultation helps with a bladder infection
- Simple or complicated?: Whether you can be treated now, or need a urine culture first.
- Symptoms that point elsewhere: The prostate, an STI, thrush, a kidney stone or the kidneys themselves.
- Men and older adults: Why the rules are different, and what the urine test is for.
- A clear safety net: What improvement to expect, and which changes need in-person care.
What the doctor checks in an online bladder infection consultation
The doctor asks about the signs of a kidney infection or sepsis first, then about the bladder. The doctor asks about:
- Warning signs: a high temperature or one below 36°C, shivering, back or side pain under the ribs, being sick, or new confusion.
- Bladder symptoms: burning or stinging, needing to pee often or urgently, getting up at night, cloudy or bloody urine.
- Who you are: your age and sex, pregnancy, a catheter, diabetes, a weakened immune system or kidney problems.
- Other clues: discharge, itching, a new partner, pain in the testicles or when ejaculating, or difficulty peeing.
- Your history: earlier infections, urine results and antibiotics, and how quickly infections have come back.
If you need a urine culture, the doctor tells you why and where. A sample should be taken before antibiotics start.
What are the symptoms of a bladder infection?
The early signs are burning or stinging when you pee and needing to pee more often, including at night. Other symptoms are:
- a sudden need to pee
- cloudy urine, or blood in the urine
- pain low in the tummy
- feeling tired or weak
In women under 65, burning when peeing, new getting up at night to pee, and cloudy urine are the three signs doctors rely on most. A high temperature, shivering, or pain in the back or side under the ribs means the infection may have reached the kidneys.
What causes cloudy urine?
Cloudy urine together with burning or needing to pee at night points to a bladder infection. Dark or smelly urine on its own, without other symptoms, often means you are not drinking enough.
Bladder infection, cystitis or UTI?
They overlap. A UTI is any infection of the urinary tract; a bladder infection, often called cystitis, is the most common kind. The cystitis page covers women’s repeat infections and prevention, and the UTI page urine infections in general.
Simple or complicated: who needs a urine test first?
Doctors treat a bladder infection differently depending on who has it. A complicated infection is one in a man, in pregnancy, with a catheter or an abnormal urinary tract, with a weakened immune system, or one that may involve the kidneys; these need a urine culture before antibiotics. This is what UK guidance advises:
Swipe sideways to compare →
| Who | What is different | What happens |
|---|---|---|
| Women under 65, not pregnant | Symptoms guide treatment; a dipstick test helps only when there is a single symptom | Usually treated online, often with a 3-day course |
| Men | Dipsticks cannot rule an infection out; the prostate may be involved | A urine culture before antibiotics, usually a 7-day course, in person |
| Pregnancy | Treatment must be safe for the baby | A urine culture and a 7-day course, in person |
| Adults over 65 | Dipsticks are not used; bacteria without symptoms are common and are not treated | Treatment for new symptoms or new confusion, often after an in-person check |
| A urinary catheter | Dipsticks are not used; most long-term catheters have bacteria in them | Treatment for symptoms, and the catheter changed without delaying antibiotics |
| Diabetes, a weakened immune system or kidney problems | A higher risk of complications | An urgent assessment, usually with a urine culture |
Bladder infections in men
Bladder infections are less common in men, because the urethra is longer, so an infection in a man is always treated as complicated. A urine sample goes for culture before antibiotics start, the usual course is 7 days, and the antibiotic is chosen with the prostate in mind. An enlarged prostate makes infections more likely by stopping the bladder emptying fully.
When the prostate is involved
Prostatitis, an inflamed prostate usually caused by an infection, can cause pain when peeing, difficulty or straining to pee, needing to pee more often, pain when you ejaculate, a high temperature, and pain in the penis, testicles or bottom. It is treated with antibiotics, and most men feel better within 2 weeks, though full recovery can take several weeks. Symptoms for 3 months or more are called chronic prostatitis.
Burning with a discharge from the penis points to urethritis or another STI, which needs STI tests rather than cystitis treatment, and pain or swelling in a testicle to epididymitis. Men over 50 who struggle to pee can read about the enlarged prostate.
Bladder infections in older adults and people with a catheter
In older or frail people, a bladder infection may show up as new confusion or agitation, leaking urine more than usual, or new shivering, rather than burning. Doctors look for new symptoms, such as new pain when peeing, new urgency or leaking, a temperature, shaking chills or new confusion.
Urine dipstick tests are not used in people over 65 or with a catheter. Bacteria in the urine without symptoms are common at that age and in almost everyone with a long-term catheter; they are not harmful, and treating them with antibiotics does not help and may cause harm. Dark or smelly urine alone, in someone who is otherwise well, often means not drinking enough rather than an infection.
With a catheter, an infection is treated when it causes symptoms, and the catheter is changed if possible, without letting that delay the antibiotics.
When is it more than a bladder infection?
Burning and needing to pee often have other causes, and some need different treatment. These clues help:

| Condition | Clues | What to do |
|---|---|---|
| Kidney infection | A high temperature, back or side pain, being sick | Urgent in-person care |
| Prostatitis | In men: difficulty peeing, pain when ejaculating, pain in the testicles or bottom, a temperature | In-person care, with a urine culture |
| An STI, such as trichomoniasis or chlamydia | Discharge, pain when peeing, a new partner | STI tests |
| Thrush | Itching and irritation, and a white discharge like cottage cheese | Antifungal treatment |
| Kidney stones | Bad pain in the side, back or groin that comes and goes | Urgent help for severe pain or a temperature |
| Blood in urine without infection | Blood with no other urinary symptoms, or blood that stays after treatment | Tests, urgently from 45 with visible blood |
| Bladder pain syndrome | Pain and a constant urge to pee, with negative urine tests | Assessment and specialist care |
What causes bladder pain without infection?
Bladder pain syndrome, also called interstitial cystitis, causes pain in the lower tummy and a frequent urge to pee without an infection, and is more common in women over 40. A long-term infection that short courses and standard urine tests miss is another cause. The cystitis page explains bladder pain syndrome.
Which bladder infection treatment might the doctor recommend?
Treatment depends on who has the infection and how unwell they are. This is the framework the doctors use, in line with NICE and UKHSA guidance:
Swipe sideways to compare →
| What you have | Likely first step | Suitable for online care? | When in-person care is needed |
|---|---|---|---|
| Typical symptoms in a woman under 65, not pregnant | Self-care or a 3-day antibiotic course | Yes | If not improving 48 hours after starting |
| Symptoms in a man | A urine culture, then usually 7 days of antibiotics | Initial advice only | In person, promptly |
| Symptoms in pregnancy | A urine culture and a 7-day course safe in pregnancy | Initial advice only | In person, promptly |
| An older adult with new confusion or new symptoms | An in-person check, with a urine culture | Only to assess | Promptly; call 112 for signs of sepsis |
| Symptoms with a catheter | Treatment, a catheter change and a urine culture | Only to assess | In person |
| Burning with discharge, or a new partner | STI tests | Partly | For the tests |
| A high temperature with back or side pain | Assessment for a kidney infection | No | Urgently, in person |

See available times →Treatment options for a bladder infection
What you can do yourself
- Take paracetamol for pain and a temperature, or ibuprofen if it suits you.
- Rest, and drink enough to pass pale urine regularly.
- Avoid drinks that irritate the bladder, such as fruit juice, coffee and alcohol.
- Take every dose of any antibiotic you are prescribed, even when you feel better.
- If you need a urine culture, give the sample before starting antibiotics.
Prescription treatment
A prescription is never issued without a consultation. For a bladder infection in a woman who is not pregnant, the doctor may prescribe a short antibiotic course, such as nitrofurantoin or trimethoprim, or a prescription to use if symptoms have not improved after 48 hours. Infections in men, in pregnancy and with a catheter are treated after a urine culture, with a course chosen for the person. If the doctor prescribes, use the prescription at a pharmacy near you.
What does not help
Antibiotics for bacteria found on a test in an older person without symptoms. Dipstick tests to rule out an infection in a man. Cystitis sachets and cranberry drinks to treat an infection. Leftover antibiotics, which may be the wrong medicine.
Special situations
Pregnancy
A bladder infection in pregnancy always needs a urine culture and a 7-day course safe for the baby, so it is assessed in person. The bladder problems in pregnancy page covers more.
Diabetes, a weakened immune system or kidney problems
These raise the risk of complications, so urinary symptoms need an urgent assessment and usually a urine culture.
A bladder infection while travelling in Europe
Drink enough in hot weather and on long journeys, and do not hold in urine. A woman with simple cystitis can be assessed by video wherever she is staying; a man, a pregnant woman, or anyone with a high temperature or back pain needs a doctor in person locally. Keep the result of any urine culture and the name of the antibiotic.
Children
Mobi Doctor consultations are for adults aged 18 and over. A child who is unwell needs a paediatrician or a local doctor in person, and emergency signs in a child mean 112.
When a bladder infection is treated online, and when you need in-person care
Treated online: bladder infections in women who are not pregnant, repeat episodes you recognise, advice on whether a urine test is needed, and follow-up when symptoms are slow to settle.
In-person care: bladder infections in men, in pregnancy and with a catheter, older adults with new confusion, symptoms with a high temperature or back pain, urine cultures, STI tests, and every emergency sign.
When to get in-person care
Call 112 or go to an emergency department now for:
- sudden confusion, slurred speech or difficulty speaking
- very fast or severely difficult breathing
- blue, grey, pale or blotchy skin, lips or tongue
- a rash that does not fade when you press a glass against it
- no longer passing urine, or being unable to pee at all
Get medical advice the same day for:
- a high temperature or one below 36°C, or feeling hot, cold or shivery
- pain in the back or side, just under the ribs
- urinary symptoms in a man, in pregnancy, or with a catheter
- new confusion or agitation with urinary symptoms in an older person
- symptoms not improving 48 hours after starting antibiotics
How Mobi Doctor works
- Book a time that suits you: daily 7am–11pm CET. You can see a doctor over video, usually within 15 minutes. No subscription, and the exact price is shown before you pay.
- Speak to a licensed doctor about your symptoms: say when they started, whether you have a temperature or back pain, and mention pregnancy, a catheter, diabetes and recent antibiotics.
- Leave with a plan: what to do, what to take and for how long, and which signs mean you should be seen in person. If the doctor prescribes, use the prescription at a pharmacy near you.
No sign-up needed
Not sure it’s a bladder infection? Tick every symptom you have to see each condition page that mentions it. It finds the right page, not a diagnosis: a doctor gives you that on a video call.

Similar symptoms, different condition? Cystitis can start the same way. Compare them, or look up any other symptom in the full symptom checker.
Frequently asked questions about bladder infections
What are the early symptoms of a bladder infection?
The early symptoms of a bladder infection are burning or stinging when you pee, needing to pee more often, including at night, a sudden need to go, and cloudy urine. A high temperature or back pain suggests the kidneys are involved.
What is the difference between cystitis and a UTI?
A UTI is any infection of the urinary tract. Cystitis is a bladder infection, the most common kind of UTI. A kidney infection is a more serious UTI that needs in-person care.
What is a complicated UTI?
A urine infection in a man, in pregnancy, with a catheter or an abnormal urinary tract, with a weakened immune system, or one that may involve the kidneys. These need a urine culture before antibiotics.
What causes cloudy urine?
Cloudy urine with burning or getting up at night to pee points to a bladder infection. Dark or smelly urine on its own often means you are not drinking enough.
Can men get bladder infections?
Yes, though less often than women. In men bladder infections are treated as complicated: a urine culture before antibiotics, usually a 7-day course, and a check for prostate involvement.
How can I prevent bladder infections?
Drink regularly through the day, do not hold urine in, pee soon after sex, wipe from front to back, avoid spermicide and diaphragms if infections follow their use, wear cotton underwear and avoid scented washes, keep diabetes controlled, and after the menopause ask about vaginal oestrogen, which restores the protective bacteria; cranberry products help some women a little, and for 2 or more bladder infections in 6 months a doctor can offer a prevention plan.
Why do older people get confused with a bladder infection?
In older or frail people, an infection can show up as new confusion or agitation, leaking urine or shivering rather than burning. New confusion needs prompt assessment, and signs of sepsis need 112.
Should a urine dipstick be used in older people?
No. Dipsticks for a bladder infection are not used over 65 or with a catheter, because bacteria without symptoms are common and treating them does not help. Doctors look for new symptoms instead.
Can a bladder infection go away on its own?
Mild cystitis in women can clear by itself, which is why waiting 48 hours with self-care is sometimes suggested. Infections in men, in pregnancy or with a temperature need treatment.
What can I do at home for a bladder infection?
Drink enough that your urine stays pale, take paracetamol or ibuprofen for the pain, pee when you need to rather than holding on, empty the bladder fully, avoid alcohol, caffeine and spicy food while it stings, and rest; a hot water bottle low on the tummy eases the ache. Mild bladder infections in women sometimes clear within a few days with this alone, but a fever, back pain, blood in the urine or symptoms lasting more than 2 days need a consultation.
What causes bladder pain without infection?
Bladder pain syndrome, also called interstitial cystitis, is a common cause, especially in women over 40. A long-term infection that standard tests miss can also cause it.
When is a bladder infection an emergency?
With a bladder infection, call 112 for sudden confusion, slurred speech, very fast breathing, blue, grey, pale or blotchy skin, a rash that does not fade, or no longer passing urine. A temperature with back pain needs urgent in-person care.
Can an online doctor treat a bladder infection?
Yes, usually. In women who are not pregnant, a doctor can recognise a bladder infection by video and prescribe treatment. Men, pregnancy, catheters and signs of a kidney infection need a urine test in person.
