Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. A typical bladder infection in an otherwise healthy, non-pregnant woman is diagnosed from the symptoms, so the doctor assesses by video and prescribes a 3-day first-line antibiotic; men, pregnant women, catheter users, and fever with back pain need in-person tests.
- What it is: infection of the bladder or urethra by bowel bacteria, E. coli in about 8 in 10 cases; about half of women have at least one UTI and 1 in 4 get another within 6 months; men, children and people over 65 are assessed differently.
- How long: antibiotics ease UTI symptoms within 48 hours and clear them in 3 to 5 days; up to half of mild bladder infections settle within a week with fluids and pain relief alone; no improvement 48 hours into antibiotics means a urine culture is needed.
- Kidney infection: fever, shivering, pain in the back or side below the ribs, nausea or vomiting with urinary symptoms mean the infection has reached a kidney, which needs in-person assessment and a 7 to 14 day antibiotic course without delay, not an online prescription.
- Recurrent: 2 UTIs in 6 months or 3 in a year is recurrent cystitis; the prevention plan runs from fluids, urinating after sex and stopping spermicide to vaginal oestrogen after the menopause, D-mannose, methenamine or a 6-month course of low-dose antibiotic.
- Emergency: call 112 for confusion or drowsiness, a racing pulse with a fever and shivering, very little urine, or collapse with urinary symptoms, which can be sepsis from a UTI; go to an emergency department if you cannot pass urine at all.
Online care suits straightforward bladder infections in otherwise healthy, non-pregnant women. Arrange prompt in-person care instead if you have fever with pain in your back or side, blood in your urine together with fever, if you are pregnant, if you use a urinary catheter, or if you are a man with UTI symptoms. These situations need examination and urine tests, not just a quick course of tablets.
Can an online doctor treat a UTI?
Yes, for uncomplicated cases. In otherwise healthy, non-pregnant women, a urinary tract infection is usually diagnosed from typical symptoms alone, so a video consultation can often provide enough information to start a short antibiotic course.[1] Complicated cases, including men, pregnancy and possible kidney infection, need in-person testing.
For a typical bladder infection in an otherwise healthy, non-pregnant woman, you can also start with an Express Assessment for UTI: a short online questionnaire that a licensed doctor reviews. If the doctor needs to speak to you, the video call is included.
The doctors on Mobi Doctor apply exactly that division. Symptom-based treatment is the European standard for uncomplicated cystitis precisely because urine tests rarely change the decision, while higher-risk groups genuinely need a culture and examination first. A trustworthy online service uses both rules and tells you plainly which side of the line you are on.

How an online consultation helps with a UTI
- Seen over video, usually within 15 minutes: in otherwise healthy women, an uncomplicated UTI can usually be diagnosed from the symptoms alone, so a video consultation is often all that is needed to start treatment.
- Antibiotics after a proper assessment: the doctor assesses you first. If your symptoms point to a bacterial bladder infection, a short first-line course can be prescribed and sent to a local pharmacy.
- Honest triage: the doctor actively checks for the situations that need urine tests or examination (pregnancy, male UTIs, kidney-infection warning signs) and tells you plainly when online care is not the right route.
- Recurrence planning: if infections keep coming back, the doctor maps the pattern with you, explains prevention that actually works, and arranges the tests a recurrent UTI deserves.
What are the symptoms of a UTI?
The classic symptoms of a lower urinary tract infection are burning when you urinate, needing to go more often and more urgently while passing only small amounts, cloudy or strong-smelling urine, and an ache low in the abdomen. Fever with back or side pain suggests the infection has reached a kidney and needs same-day in-person care.
- Burning or stinging when you urinate
- Needing to urinate more often and more urgently, yet passing only small amounts
- Cloudy, dark or strong-smelling urine
- An ache or pressure low in the abdomen
- Urine that looks pink or blood-tinged
- Feeling tired, achy and generally off-colour
- Warning signs: fever, chills, or pain in the back or side just below the ribs
In older adults, a UTI can show up less typically, sometimes as new confusion, unsteadiness or a sudden change in behaviour rather than burning, and it deserves a lower threshold for medical review.
UTI, cystitis or bladder infection: what is the difference?
The three names largely describe the same problem from different angles. Urinary tract infection (UTI) is the umbrella term for infection anywhere in the urinary system, while cystitis means inflammation of the bladder, nearly always caused by a bacterial bladder infection, by far the most common type of UTI.
When bacteria travel up to the kidneys, the result is a kidney infection (pyelonephritis), which is more serious and always needs in-person assessment. Whichever term you searched for, the assessment and treatment described here are the same.
Why women get UTIs so much more often
A woman's urethra is short and sits close to the back passage, so gut bacteria, usually E. coli, reach the bladder easily. Sex, spermicide-based contraception, a family history of UTIs and the oestrogen changes of menopause all raise the risk. Cystitis is one of the most common reasons women seek medical care, so there is nothing unusual, and nothing embarrassing, about needing treatment for it.
Is it a UTI, thrush or an STI?
Burning when you urinate has three common causes: a urinary tract infection, vaginal thrush, and sexually transmitted infections such as chlamydia. A UTI typically adds urgency, frequency and cloudy urine; thrush adds itching and a thick white discharge; an STI may add unusual discharge or bleeding after unprotected sex. The combination of symptoms usually separates them.
This overlap is why the doctor asks about discharge, itching and recent sexual history, not from nosiness, but because antibiotics for a UTI will do nothing for thrush, and a missed sexually transmitted infection keeps causing harm. Burning with discharge in men points to urethritis, which needs STI testing rather than cystitis treatment. If your story does not clearly fit a bladder infection, the honest next step is a urine test or an STI screen, and the doctor tells you which and where.
Is your UTI suitable for online care?
It depends on whether the infection is uncomplicated or complicated. Uncomplicated cystitis in an otherwise healthy, non-pregnant woman is well suited to a video consultation, with treatment when the doctor confirms it is right for you. Complicated cases, and anything with kidney-infection warning signs, need examination and urine tests first. This is the framework the doctors use, aligned with European urological guidance.[1]

| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Typical cystitis in an otherwise healthy, non-pregnant woman (burning, frequency, urgency) | Short first-line antibiotic course, for example nitrofurantoin, pivmecillinam or fosfomycin[2] | Usually yes | No improvement within about 48 hours, or symptoms that do not fit |
| Recurrent UTIs (two in six months or three in a year) | Urine culture, trigger review and a prevention plan[3] | Often, as the starting point | Tests arranged locally; refer if results are abnormal |
| Fever with back or side pain, nausea, feeling very unwell (possible kidney infection) | Prompt examination and urine culture | No | Same-day in-person care |
| UTI in a man, in pregnancy, or with a urinary catheter | Urine culture and examination first | Initial advice only | In-person testing and tailored, sometimes longer, treatment |

See available times →What the doctor checks in an online UTI consultation
The assessment is structured, not a quick look at a form. In a UTI consultation, the doctor will typically check:
- Your exact symptoms and how long you have had them: burning, frequency and urgency, and whether the picture fits a lower UTI or points elsewhere.
- Red-flag signs: fever, chills, pain in the back or side, nausea or vomiting, which suggest a kidney infection and need in-person care rather than a remote prescription.
- Whether you could be pregnant: pregnancy changes which antibiotics are safe and always needs a urine culture and in-person review.
- Blood in the urine, and whether this is a first or a repeat infection.
- Recent antibiotics and previous cultures: what you took, whether it worked, and any known resistant organisms.
- Allergies, kidney function and other conditions such as diabetes, which affect the choice and length of the course.[2]
- Who you are: a UTI in a man, a catheter user or an older adult with new confusion is treated as complicated from the start.
There is no examination to feel awkward about, because for uncomplicated cystitis none is needed. You can take the call from home, a car or a hotel room, nobody overhears your history in a queue, and the pharmacy simply receives a prescription like any other.
When a UTI is treated online, and when you need in-person care
Treated online: uncomplicated lower UTIs in otherwise healthy, non-pregnant women with typical symptoms; repeat episodes you recognise; and the starting assessment for recurrent infections, alongside the tests those need.[3] The doctor also agrees a safety net with you: what improvement to expect by when, and exactly which changes should prompt in-person care instead.
In-person care: suspected kidney infection (fever with back or side pain, feeling very unwell); UTIs in men, which often involve the prostate and need investigation; UTIs in pregnancy, which need a urine culture and pregnancy-safe choices; catheter-related infections, which often need a catheter change; and symptoms that do not clearly fit a bladder infection, where a urine test, an examination or an assessment for urethritis is the honest next step. In those cases the consultation buys you a proper plan and the right local test, not a blind course of tablets.
How can I stop UTIs coming back?
Prevention that works: drink enough fluid through the day, do not habitually hold on when you need to go, urinate soon after sex, and avoid spermicides if you use them. After menopause, topical vaginal oestrogen reduces recurrences. For frequent infections, doctors can add non-antibiotic preventives or, in selected cases, standby antibiotics, agreed as a plan rather than repeated emergency courses.[3]
If infections cluster around sex, a single preventive antibiotic dose taken after intercourse can be more sensible than repeated treatment courses, one of several patterns worth naming to the doctor. Some countries also use methenamine hippurate, a non-antibiotic urinary antiseptic, as a preventive option. Neither is a self-start decision; both belong in a plan agreed after a proper recurrent-UTI review.
What probably does not help
Cranberry products, despite their reputation, are not a treatment for an active infection. At best they may modestly reduce recurrences for some women, and the evidence for D-mannose is similarly mixed. Vigorous intimate hygiene works against you: harsh washes and douching irritate the very tissues you are trying to protect. Washing with water or a plain emollient is enough.
Treatment options for UTIs
What you can do yourself
Drink enough that your urine runs pale, and take paracetamol or ibuprofen for the burning and the low tummy ache. Very mild cystitis sometimes settles within a couple of days with fluids and pain relief alone, so with mild symptoms it is reasonable to hold off briefly, as long as you get medical advice if things worsen, fever appears or you are no better after two days. Avoid caffeine and alcohol while symptomatic, because both irritate the bladder.
Prescription treatment
For an uncomplicated bladder infection, first-line treatment is a short antibiotic course, commonly three to five days of nitrofurantoin or pivmecillinam, or a single dose of fosfomycin, depending on what is available in your country, your allergies, your kidney function and what you have taken before.[2] A prescription is never issued without a consultation, so the doctor confirms the picture fits before any antibiotic is chosen. Antibiotics are only prescribed when your symptoms genuinely point to a bacterial infection: they do nothing for bladder irritation without infection, and unnecessary courses drive resistance, so the doctor matches the shortest effective course to your situation.[4][5] If you are not clearly improving within about 48 hours of starting antibiotics, follow up, because you may need a urine culture and a different antibiotic, and treating blind a second time is exactly what good stewardship avoids.
When to get in-person care
A UTI that spreads to the kidneys or bloodstream is serious. Get same-day in-person care for fever with chills, pain in your back or side just below the ribs, nausea or vomiting, or feeling markedly unwell with urinary symptoms. If you or someone with a UTI becomes confused or unusually drowsy, breathes rapidly, has mottled or cold skin, or stops passing urine (possible signs of sepsis), call 112 immediately.
Treating a UTI at home: what helps and what does not
Drinking plenty of water, taking simple pain relief and avoiding caffeine and alcohol genuinely ease UTI discomfort while you decide what to do next. Cranberry products are popular, but the evidence that they treat an active infection is weak, and no amount of water flushes out established bacteria.
What home care cannot do: a urinary tract infection is bacterial, and home remedies do not clear bacteria. Most UTIs in women need a short course of antibiotics, which is prescription-only across the EU. Waiting it out risks the infection climbing to the kidneys: fever, shaking or pain in your back or side alongside urinary symptoms means urgent care, not more water.
You do not have to leave home for that step either: you can see a licensed doctor over video from home, usually within 15 minutes; if treatment is right for you, the prescription can be used at a pharmacy near you. Book a video consultation: no subscription, exact price before payment.
Is a UTI contagious?
No. A urinary tract infection cannot be caught from another person, a toilet seat, a towel or a swimming pool, and it is not an STI.
The sex nuance: sex can mechanically push bacteria toward the bladder, which is why UTIs often follow it, but that is cause, not contagion; a partner does not need treatment.
What contagion worry usually is: if there is discharge, sores or a new partner in the picture, the honest question is an STI check rather than a UTI, and a doctor can sort which is which in one conversation.
How long does a UTI last?
With the right antibiotics, most women feel distinctly better within 24 to 48 hours, and a short course usually clears the infection. Untreated, a UTI can drag on for a week or more, and waiting it out is a gamble on your kidneys, not a neutral choice.
Wanting it gone fast? The quickest legitimate route is a doctor's assessment: you can see a doctor over video, usually within 15 minutes. Antibiotics follow only when the doctor decides they are right, with a prescription you can use at a pharmacy near you. Book a video consultation: the exact price is shown before you pay.
Can you treat a UTI without antibiotics?
Sometimes, honestly: a mild bladder infection in an otherwise healthy woman can settle by itself, and doctors sometimes agree a day or two of fluids and pain relief as a deliberate, reviewed plan.
What that plan is not: cranberry, bicarbonate and water alone do not reliably clear an established infection, and symptoms that are worsening, lasting beyond two days, or arriving with fever or back pain need antibiotics and sometimes urgently. The safe version of without antibiotics is a decision made with a doctor, not instead of one.

Frequently asked questions about UTIs
What is a UTI, and what causes it?
A urinary tract infection (UTI) is a bacterial infection anywhere from the urethra to the kidneys, most often cystitis, an infection of the bladder. It is caused by bacteria from the bowel, E. coli in about 8 in 10 cases, entering the urethra and multiplying in the bladder; the short female urethra, sex, spermicides, wiping back to front, not emptying the bladder fully, the menopause, pregnancy, diabetes, kidney stones and catheters all raise the risk.
What are the symptoms of a UTI?
A UTI causes burning or stinging when passing urine, needing to go often, urgently and at night while passing only small amounts, cloudy, dark, strong-smelling or bloody urine, and an ache low in the abdomen. Fever, shivering, pain in the back or side and vomiting mean the infection has reached a kidney. In older or frail people a UTI can show as new confusion, unsteadiness or worse incontinence rather than urinary symptoms.
Can an online doctor prescribe UTI antibiotics in Europe?
Yes, in appropriate cases. For an otherwise healthy, non-pregnant woman with typical bladder-infection symptoms, European guidance supports diagnosis from the symptoms, so the doctor can prescribe a short first-line antibiotic course by video, with the prescription usable at a pharmacy near you, choosing the antibiotic by your country's resistance patterns and your allergies. A prescription is never issued without a consultation, and men, pregnant women and anyone with fever are seen in person.
Is cystitis the same thing as a UTI?
Almost. Cystitis means inflammation of the bladder, which is nearly always caused by a bacterial bladder infection, the commonest form of urinary tract infection; urethritis is a UTI of the urethra, and pyelonephritis a UTI of the kidney. For the usual burning-and-frequency picture, doctors use cystitis and UTI interchangeably, and the assessment and treatment are the same. Interstitial cystitis, or bladder pain syndrome, is a different, non-infectious condition.
Do I need a urine test before starting UTI antibiotics?
Not usually. In healthy, non-pregnant women with classic symptoms, a dipstick or culture rarely changes the decision, so treatment does not wait for a test. A urine culture matters if you are pregnant or male, if UTIs keep returning, if symptoms have not improved 48 hours into antibiotics, after a kidney infection, or if you use a catheter, because it names the bacteria and the antibiotics they respond to.
Do UTIs go away on their own?
Sometimes. Up to half of mild bladder infections settle within a week with plenty of fluids and pain relief, and holding off antibiotics for 48 hours is reasonable when symptoms are mild and there is no fever. Antibiotics shorten a UTI by a few days, relieve the burning fastest and reduce the small risk of the infection climbing to a kidney, so they are the better choice when symptoms are significant or worsening.
What if UTI symptoms come back soon after treatment?
Book a follow-up rather than repeating the same course. Symptoms returning within two weeks of treatment usually mean the bacteria were resistant to the first antibiotic or the infection was never fully cleared, so a urine culture is needed before the next course. A UTI that returns within six months counts towards recurrent cystitis, which gets a prevention plan rather than course after course, and in a man prompts a scan of the urinary tract.
How long does a UTI last?
With antibiotics, UTI symptoms ease within 24 to 48 hours and are usually gone within 3 to 5 days, though a little urgency can linger for a week. Without antibiotics, a mild cystitis lasts about a week and may clear on its own, or may persist. Symptoms lasting beyond a week, worsening after 48 hours of treatment, or joined by fever or back pain need review, because the infection may have reached a kidney.
What can I do at home for a UTI?
Drink enough to pass pale urine regularly without forcing litres, take paracetamol or ibuprofen for pain, rest, empty the bladder fully and often, avoid alcohol, caffeine, fruit juice and fizzy drinks that irritate the bladder, use a hot-water bottle on the lower abdomen, and avoid sex until the UTI has settled. Cystitis sachets and cranberry juice do not treat an existing infection, and leftover antibiotics should never be used.
How can I prevent UTIs coming back?
Prevent UTIs by drinking enough through the day, urinating when you need to and fully, passing urine soon after sex, wiping front to back, avoiding spermicides and diaphragms, skipping perfumed soaps and douches, wearing cotton underwear, and treating constipation. After the menopause, vaginal oestrogen roughly halves recurrences; D-mannose and cranberry have some evidence; and for frequent infections a doctor can offer methenamine, a single antibiotic dose after sex, or a 6-month low-dose course.
Are UTIs different for men, in pregnancy or in older people?
Yes. A UTI in a man is uncommon and may involve the prostate, so it needs a urine culture, a 7-day course and often a scan. In pregnancy, even a UTI without symptoms is treated because it can trigger a kidney infection and premature labour, with pregnancy-safe antibiotics and a test of cure. Over 65, a UTI can present as confusion, and bacteria without symptoms are not treated; all three are seen in person.
Is it a UTI, thrush, an STI or bladder pain syndrome?
Burning with frequency and cloudy urine points to a UTI; itching with a thick white discharge to thrush; burning with discharge after a new partner to chlamydia or gonorrhoea; pain on urinating with blisters to herpes; and months of bladder pain with frequency but repeatedly sterile urine to bladder pain syndrome. After the menopause, vaginal dryness causes UTI-like stinging. The doctor sorts these by the history and, where needed, a urine test and swab.
