Break the cycle
Recurrent UTIs: what helps, what doesn't, and why.
Doctors call a UTI recurrent after two infections in six months, or three in a year.3 Most women just call it the cycle: you feel fine, then the burning starts, you take antibiotics, you feel fine again — and quietly wonder how long it will last this time.
Antibiotics are essential for treating an active infection. But on their own, they don't stop the next one, and they can bring side effects such as yeast infections.9 This page explains what research says about recurrence and what actually lowers your risk.

The basics
Acute, recurrent or chronic?
Acute
A single bacterial infection of the bladder, urethra or kidneys — most often E. coli from the gut.1
Recurrent
Two confirmed infections in six months, or three in a year.3
Chronic
Used for infections that never seem to fully go away. Studies have found bacteria forming protected communities inside bladder-lining cells.7
The evidence
The science we build on
Five pillars, each aimed at a different step in how UTIs start and return.
D-mannose: anti-adhesion
Most UTIs start when E. coli grips the bladder wall with tiny hooks called FimH. D-mannose binds to those hooks, so bacteria are more likely to be flushed out than to anchor. In a randomised trial, women taking D-mannose had recurrence rates similar to those on the antibiotic nitrofurantoin, and the German S3 guideline lists it as a non-antibiotic option. Not every trial agrees, so research is ongoing.5,13
The intimacy trigger
Sex is one of the strongest known risk factors: a landmark NEJM study found UTI risk rose sharply with recent intercourse. Friction and tiny irritations make it easier for bacteria to travel up. That is why we include a physical silicone barrier for the moments around intimacy.14
Urinary alkalisation
Shifting urine away from harsh acidity is a long-used way to ease the burning during a flare. Potassium citrate does exactly that. Evidence from trials is still limited, so we treat it as comfort support, never as a replacement for treatment.15
Targeted probiotics
Specific strains, L. rhamnosus and L. reuteri, have been shown to survive the gut and support a lactobacillus-rich vaginal flora, which helps keep pH healthy and crowds out the bacteria behind UTIs. In a trial against antibiotics they were less effective, but did not drive resistance.16,17
Acid-free botanicals
Hibiscus sabdariffa is rich in anthocyanins and polyphenols, which lab studies link to anti-adhesion and bacterial inhibition, without the citric and quinic acids that can sting an inflamed bladder. Human evidence is early.18

How often do you get UTIs?
UTI 101
The facts, calmly explained.
Six short chapters on how UTIs work. No scare stories, just what research and health services tell us.
Chapter 1What a UTI actually is
A urinary tract infection happens when bacteria, most often E. coli from the gut, reach the urethra and bladder. Bladder infections (cystitis) are the most common kind. If an infection travels up to the kidneys, it becomes more serious.
Women get UTIs far more often than men, mostly because of anatomy: the urethra is short and close to the vagina and anus. It is not a sign of poor hygiene.1,10
Chapter 2Common signs, and when not to wait
Typical signs are burning or pain when you pee, needing to go often or urgently, cloudy or strong-smelling urine and pressure low in the tummy. Blood in the urine can also happen.
Contact a doctor the same day if you have a fever or chills, pain in your back or side, nausea, or feel generally unwell. These can mean the infection has reached the kidneys. Pregnancy, symptoms that keep returning, or symptoms that do not improve also need a doctor.10
Chapter 3Why it burns
The burning is not bacteria "biting". When bacteria attach to the bladder lining, your immune system responds with inflammation. The lining becomes sensitive, and urine passing over it stings.
The bladder muscle can also become irritable, which is why you feel you need to go again a minute after you have been.7,10
Chapter 4Bladder or vagina?
Burning, urgency and frequency usually point towards the bladder. Changed discharge, itching or a different smell usually point towards the vagina, such as thrush or bacterial vaginosis. The symptoms can overlap.
This matters because each needs different care. Treating the wrong one can delay the right help, so if you are unsure, ask a doctor or sexual health clinic.10,11
Chapter 5Antibiotics, resistance and the yeast loop
Antibiotics are the right treatment for a confirmed bacterial infection. Resistance means the bacteria become harder to treat, not your body. Repeated or unnecessary courses can make that more likely over time.
Antibiotics can also disturb the protective bacteria in the vagina. For some women, that is followed by thrush, whose itching and burning can feel like a UTI coming back. Telling your doctor about this pattern helps them choose the next step.3,9
Chapter 6Everyday care, kept simple
The vagina cleans itself. Warm water on the outside is enough; scented washes, douches and wipes can disturb the natural balance.
Drinking enough fluid has trial evidence behind it for women who drink little. Spermicides can raise UTI risk, so it is worth discussing contraception if infections follow sex. After menopause, vaginal estrogen is a recommended option to ask about.3,4,12
It's nuanced
We need antibiotics — used precisely.
An active infection often needs antibiotics, and guidelines recommend them when an infection is confirmed.3 If you have a fever, back or side pain, or feel unwell all over, see a doctor straight away.
The problem is relying on them as the only plan. Prevention between infections — the part Evere is built for — aims for fewer courses and less disruption to your microbiome.6
