Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. Cystitis in women who are not pregnant is recognised from the symptoms and treated by video; men, pregnancy and signs of a kidney infection need a urine test in person.
- What it is: inflammation of the bladder, usually from a bacterial infection. Over half of women have cystitis at some time in their lives.
- Treatment: mild cystitis can clear on its own; when antibiotics are needed, women usually take a 3-day course.
- Keeps coming back: 2 or more infections in 6 months, or 3 or more in a year, count as recurrent, and guidelines set out steps to prevent them.
- Emergency: call 112 for confusion, drowsiness, very fast breathing, blue, pale or blotchy skin, or no longer passing urine.
Do not book a video appointment if you are confused or drowsy, are breathing very fast, have blue, pale or blotchy skin, or have stopped passing urine: call 112. A high temperature with pain in your back or side, or cystitis in pregnancy or in a man, needs an in-person assessment with a urine test.
Can an online doctor treat cystitis?
Yes, usually. In women who are not pregnant, cystitis is recognised from typical symptoms, so a doctor can assess it by video, check that thrush, an STI or a kidney infection does not fit better, and prescribe a short antibiotic course when it is right for you, or suggest self-care first for mild symptoms. Cystitis in men or in pregnancy, symptoms with a high temperature or back pain, and bladder pain without infection need a urine test or an examination in person.

How an online consultation helps with cystitis
- Cystitis or something else?: Itching or discharge point to thrush or an STI, and a temperature with back pain to the kidneys.
- Antibiotics only when they help: Self-care first for mild symptoms, or a short course chosen around your allergies, kidneys and earlier results.
- A plan if it keeps coming back: The steps guidelines recommend, from simple habits to vaginal oestrogen and preventive treatment.
- Bladder pain without infection: When repeated ‘cystitis’ is really interstitial cystitis, and what helps it.
What the doctor checks in an online cystitis consultation
The doctor asks about the signs of a kidney infection or sepsis first, then about the bladder symptoms. The doctor asks about:
- Warning signs: a high temperature, shivering, pain in the back or side under the ribs, feeling or being sick, or confusion.
- Bladder symptoms: burning or stinging, needing to pee often and urgently, cloudy or bloody urine, and pain low in the tummy.
- Vaginal symptoms: itching, soreness or discharge, which point to thrush or an STI rather than cystitis.
- Timing: whether infections follow sex, and how many you have had in the last 6 and 12 months.
- Your health: pregnancy, the menopause, diabetes, a catheter, kidney problems, and earlier urine results and antibiotics.
- Your medicines: allergies and everything you take, including contraception.
Before the call, note when the symptoms started and what you have already tried. If you need a urine test, the doctor tells you where and why.
What is cystitis, and why do women get it?
Cystitis means inflammation of the bladder. It is usually caused by bacteria, often from poo, getting into the bladder through the urethra, the tube you pee through. It affects over half of women at some time in their lives, because a woman’s urethra is short and its opening is close to the vagina and anus.
Is cystitis a UTI?
Yes. Cystitis is a bladder infection, the most common kind of urinary tract infection (UTI). If the infection spreads to the kidneys, it becomes a kidney infection, which is more serious. The UTI page covers urine infections in general.
What triggers cystitis?
Swipe sideways to compare →
| Trigger | What helps |
|---|---|
| Sex | Wash around the vagina with plain water before and after sex, and pee soon after |
| Wiping from back to front | Wipe from front to back |
| Spermicide, including spermicidal lubricant on condoms or a diaphragm | Ask about another form of contraception |
| The menopause | Vaginal oestrogen, if infections keep coming back |
| Not drinking enough | Drink enough to keep your urine pale |
| Holding in urine, or rushing | Go when you need to, and empty your bladder fully |
| Scented soaps, bubble baths and vaginal deodorants | Use plain water or an unperfumed soap |
| Diabetes, kidney stones or a catheter | Tell the doctor: they make infections more likely |
How do you get rid of cystitis fast?
Mild cystitis can clear on its own, so for some women the doctor suggests self-care and waiting 48 hours before antibiotics, with a prescription to use if the symptoms do not start to improve or get worse. When antibiotics are needed, women who are not pregnant usually take a 3-day course, most often nitrofurantoin or trimethoprim. If you are not improving within 48 hours of starting, or you get worse at any time, you need a review.
These steps ease the symptoms while it clears:
- Take paracetamol, or ibuprofen if it suits you, for the pain.
- Drink enough fluids to pass pale urine regularly.
- Hold a hot water bottle on your tummy or between your thighs.
- Avoid drinks that irritate the bladder, such as fruit juice, coffee, strong tea and alcohol.
- Rest, and do not take antibiotics left over from an earlier infection or from someone else.
Cystitis remedies: what the evidence says
Swipe sideways to compare →
| Remedy | What the evidence says | Verdict |
|---|---|---|
| Paracetamol or ibuprofen | Eases pain while the infection clears | Helps |
| Drinking enough fluids | Avoids dehydration | Helps |
| Cystitis sachets (potassium or sodium citrate) or bicarbonate of soda | No evidence that they ease symptoms or treat an infection; they also stop methenamine working | Not recommended |
| Cranberry juice or tablets | No evidence that they treat an infection; any benefit for prevention is uncertain | Not a treatment |
| D-mannose | Some evidence for preventing repeat infections; it is a sugar, not a medicine | An option for prevention |
| Leftover or borrowed antibiotics | May be the wrong medicine or course | Do not use |
How long does cystitis last?
Mild cystitis can clear by itself. With antibiotics, the course for women is usually 3 days. Symptoms that are not improving 48 hours after starting antibiotics, or that come back soon after, need a review and usually a urine culture.
Why do I keep getting cystitis? Recurrent cystitis
Cystitis counts as recurrent after 2 or more infections in 6 months, or 3 or more in 12 months. Repeat infections can be the same bacteria coming back or a new infection. NICE guidance sets out steps to prevent them, starting with the simplest:
Swipe sideways to compare →
| Step | What it involves | Good to know |
|---|---|---|
| 1. Habits and self-care | The triggers and habits in the table above | Reviewed whenever other steps are reviewed |
| 2. Vaginal oestrogen | A cream, pessary or other form used in the vagina, after the menopause | Very little is absorbed; HRT for the whole body is not used for this |
| 3. A single antibiotic dose after a trigger | One dose after sex, for example, when habits and oestrogen have not helped | Reviewed within 6 months |
| 4. Methenamine hippurate | A tablet that is not an antibiotic, used instead of daily antibiotics | Not with cystitis sachets, which stop it working |
| 5. A daily antibiotic | A low dose every night, after other steps | Reviewed at least every 6 months |
D-mannose is an option some women try, and the evidence for probiotics is inconclusive. Cranberry products may help some women but the benefit is uncertain, and both D-mannose and cranberry contain sugar. A urine culture is worth doing when infections keep coming back.
When repeat cystitis needs a specialist
Recurrent cystitis in men, repeated kidney infections, recurrent infections in pregnancy, and repeat infections with no clear cause need specialist advice. Symptoms that continue when urine tests are negative and short courses have failed can be a long-term (chronic) infection, which also needs a specialist.
Bladder pain without infection: interstitial cystitis
Interstitial cystitis, also called bladder pain syndrome, causes pain in the lower tummy or back and a feeling that you need to pee often, even when the bladder is empty, without an infection. It is more common in women and usually starts at 40 or over. Symptoms come and go in flare-ups, and pain during sex is common.
There is no single test: doctors rule out other causes with urine and blood tests, an examination, an ultrasound and sometimes a cystoscopy. Treatment combines a food diary and avoiding drinks and foods that make it worse, such as spicy or acidic food, caffeine and alcohol, bladder retraining, regular low-impact exercise, painkillers, medicines for nerve pain or an overactive bladder, and specialist treatments given into the bladder.
Can men get cystitis?
Yes, but it is less common, and in men it is treated as a complicated infection: a urine sample goes for culture before antibiotics start, and the course is usually 7 days. An enlarged prostate makes infections more likely. The bladder infection page explains what happens for men, and when it is more than cystitis.
Which cystitis treatment might the doctor recommend?
Treatment depends on how bad the symptoms are, who you are, and how often it happens. This is the framework the doctors use, in line with NICE guidance:
Swipe sideways to compare →
| What you have | Likely first step | Suitable for online care? | When in-person care is needed |
|---|---|---|---|
| Mild cystitis, not pregnant | Self-care, with antibiotics to start if not better in 48 hours | Yes | If symptoms worsen or a temperature develops |
| Typical cystitis, not pregnant | A 3-day antibiotic course | Yes | If not improving 48 hours after starting |
| Cystitis after sex, again and again | Habits, then a single antibiotic dose after sex | Yes | For a urine culture if the pattern changes |
| Recurrent cystitis after the menopause | Vaginal oestrogen, then other preventive steps | Yes | For a urine culture |
| Cystitis in pregnancy, or in a man | A urine culture before antibiotics | Initial advice only | In person, promptly |
| Bladder pain with negative urine tests | Assessment for interstitial cystitis | Partly | For tests and specialist care |
| A high temperature with back or side pain | Assessment for a kidney infection | No | Urgently, in person |
Burning, stinging and needing to go all the time? A doctor can tell you in one consultation what will help.

What you can do yourself
- Drink plenty of fluids, especially water, and do not hold in urine.
- Pee soon after sex, and wash around the vagina with plain water before and after.
- Wipe from front to back, and keep the genital area clean and dry.
- Wear cotton underwear, and avoid tight underwear, scented soaps, bubble baths and vaginal deodorants.
- Avoid spermicidal lubricant with condoms or a diaphragm.
- Cut down on alcohol and on sugary food and drinks.
Prescription treatment
A prescription is never issued without a consultation. For cystitis 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 do not improve within 48 hours. For cystitis that keeps coming back, the doctor may prescribe vaginal oestrogen after the menopause, a single antibiotic dose to take after sex, methenamine hippurate or a daily preventive antibiotic, with regular reviews. If the doctor prescribes, use the prescription at a pharmacy near you.
What does not help
Cystitis sachets and cranberry drinks to treat an infection. Leftover or borrowed antibiotics. Repeating antibiotics without a urine culture when they have not worked. Treating thrush or an STI as cystitis.
Special situations
Pregnancy
Cystitis in pregnancy needs a urine culture before antibiotics and a 7-day course chosen to be safe for the baby, so it is assessed in person. The bladder problems in pregnancy page covers more.
The menopause
Lower oestrogen after the menopause makes cystitis more likely, and vaginal oestrogen helps prevent it coming back. The menopause page covers the wider picture.
Older or frail women
A urine infection may show up as new confusion or agitation, leaking urine more than usual, or new shivering, rather than burning. These need an urgent assessment.
Cystitis while travelling in Europe
Heat and long journeys make it easy to drink too little and hold in urine, both of which make cystitis more likely. If you get it often, ask the doctor before you travel about a plan for an attack abroad, and remember that a high temperature with back pain needs a doctor in person wherever you are.
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 cystitis is treated online, and when you need in-person care
Treated online: cystitis in women who are not pregnant, mild cystitis managed with self-care, repeat episodes you recognise, prevention plans for recurrent cystitis, and cystitis around the menopause.
In-person care: cystitis in men or in pregnancy, symptoms with a high temperature or back pain, symptoms that do not improve with treatment, urine cultures and scans, bladder pain without infection, and every emergency sign.
When to get in-person care
Call 112 or go to an emergency department now for:
- confusion, drowsiness, or difficulty speaking
- very fast breathing
- blue, pale or blotchy skin
- no longer passing urine
Get medical advice the same day for:
- a high temperature, or feeling hot, cold or shivery, with cystitis
- pain in your back or side, just under the ribs
- blood in your urine with a temperature
- cystitis in pregnancy, or in a man
- symptoms that are 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, how often you get cystitis, and whether you could be pregnant.
- 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.

Frequently asked questions about cystitis
What is cystitis?
Cystitis is inflammation of the bladder, usually caused by bacteria getting into the bladder through the urethra. It causes burning when you pee, needing to go often and urgently, and pain low in the tummy. Over half of women get it at some time.
Is cystitis a UTI?
Yes. Cystitis is a bladder infection, the most common kind of urinary tract infection. An infection that spreads to the kidneys is more serious and needs in-person care.
What are the symptoms of cystitis?
Cystitis causes burning or stinging when you pass urine, needing to go often and urgently but passing only small amounts, getting up at night, cloudy, dark or smelly urine, sometimes blood in it, and an ache or pressure low in the tummy; most women feel generally well otherwise. A high temperature, shivering, pain in the back or side, or feeling sick means the infection may have reached the kidneys and needs prompt in-person care rather than cystitis treatment alone.
What causes cystitis?
Cystitis is caused by bacteria, often from poo, entering the bladder. Sex, wiping from back to front, spermicide, the menopause, not drinking enough, holding in urine, diabetes and catheters make it more likely.
Is it cystitis, thrush or an STI?
Cystitis burns during the stream itself, with urgency and frequency and no discharge. Thrush itches and burns on the skin as urine touches it, with thick white discharge; chlamydia and gonorrhoea can cause burning with discharge or bleeding after sex and often no urgency; genital herpes burns with sores; and interstitial cystitis brings the same symptoms with repeatedly clear urine tests. A urine test and, after a new partner, STI swabs tell them apart.
How do you get rid of cystitis fast at home?
Take paracetamol or ibuprofen, drink enough to keep your urine pale, and use a hot water bottle. Mild cystitis can clear on its own; if it does not start to improve within 48 hours, or is bad from the start, a short antibiotic course treats it.
How long does cystitis last?
Mild cystitis can clear by itself, which is why waiting 48 hours is sometimes suggested. When antibiotics are needed, women usually take a 3-day course, and symptoms that are not improving within 48 hours of starting need a review.
Does cranberry juice help cystitis?
Not as a treatment: there is no evidence that cranberry treats an infection. For preventing repeat cystitis the benefit is uncertain, and cranberry products contain sugar and should be avoided with the blood thinner warfarin.
What is the best over-the-counter treatment for cystitis?
Paracetamol or ibuprofen for the pain, and plenty of fluids. Cystitis sachets have no evidence that they help. If antibiotics are needed, they are prescribed after a consultation.
Why do I keep getting cystitis?
Sex, the menopause, spermicide and some health conditions make repeat cystitis more likely. Two or more in 6 months, or three in a year, count as recurrent, and preventive steps such as vaginal oestrogen or a single dose after sex can help.
Can cystitis go away without antibiotics?
Mild cystitis can. For some women, the doctor suggests self-care and waiting 48 hours, with antibiotics if symptoms do not improve or get worse at any time.
Can men get cystitis?
Yes, but cystitis is much less common in men, because the male urethra is longer, and it is treated as a complicated infection: a urine culture before antibiotics, usually a 7-day course, and a check for an enlarged prostate, a stone or another reason the bladder is not emptying. Cystitis in a man with fever or pain in the perineum may be prostatitis, which needs a longer course and an examination.
What is interstitial cystitis?
Interstitial cystitis is bladder pain without infection, also called bladder pain syndrome. It causes pain in the lower tummy or back and a frequent need to pee, is more common in women over 40, and is managed with diet, bladder retraining, medicines and specialist treatments.
Can an online doctor treat cystitis?
Yes, usually. In women who are not pregnant, a doctor can recognise cystitis by video and prescribe treatment when it is needed. Men, pregnancy and signs of a kidney infection need in-person care.
