A urinary tract infection (UTI) can be an uncomfortable and disruptive experience. Whether it’s a constant urge to go, a burning sensation when you wee, or general pelvic discomfort, you’re probably wondering—how long does a UTI last? The good news is that with the right treatment and care, most UTIs clear up quickly.
At Market Harborough Pharmacy, we offer convenient, pharmacist-led support for UTI symptoms through the NHS Pharmacy First service. Here’s everything you need to know about UTIs, how long they tend to last, and what you can do to recover faster.
What Is a UTI?
A UTI is an infection in any part of your urinary system—including your bladder, urethra, or kidneys. Most UTIs are caused by bacteria entering the urethra and multiplying in the bladder.
UTIs are more common in women, but men and children can get them too. They’re not usually serious when treated promptly, but if left untreated, they can lead to complications such as kidney infections.
Common Symptoms
UTI symptoms can vary in severity, but typically include:
- — A strong, persistent urge to urinate
- — A burning sensation when urinating
- — Passing small amounts of urine frequently
- — Cloudy, dark, or strong-smelling urine
- — Pain or pressure in your lower abdomen
- — Feeling generally unwell or tired
In more severe cases, you might also have:
- — Fever or chills
- — Back pain or side pain (a sign the infection may have reached your kidneys)

How Long Does a UTI Last?
With treatment, most lower urinary tract infections (such as bladder infections) begin to improve within 24–48 hours and clear completely in 3–5 days. Without antibiotics, mild UTIs may resolve on their own in about a week—but this isn’t always guaranteed.
Upper UTIs (infections that affect the kidneys) usually require a longer course of antibiotics and can take up to two weeks to fully resolve. If symptoms are left untreated or worsen, the infection could spread, so it’s best to speak to a healthcare professional early on.
When to Use Pharmacy First for UTI Symptoms
Thanks to the NHS Pharmacy First service, you can now get professional help for UTIs without needing a GP appointment. At Market Harborough Pharmacy, our trained pharmacists can assess your symptoms, provide advice, and if necessary, offer treatment such as antibiotics—right there in the pharmacy.
Pharmacy First is ideal for treating uncomplicated UTIs in women aged 16–64. If you’re experiencing typical symptoms and otherwise in good health, it’s a quick and accessible way to get the help you need.
Speeding Up Your Recovery
There are steps you can take alongside treatment to ease symptoms and help your body recover more quickly:
- — Drink plenty of fluids: This helps flush bacteria out of your system. Aim for water and avoid caffeinated or alcoholic drinks.
- — Use a hot water bottle: Placing it on your lower stomach can relieve discomfort.
- — Avoid harsh soaps and bubble baths: These can irritate the area and make symptoms worse.
- — Empty your bladder often: Don’t hold in urine; this helps remove bacteria.
- — Wear breathable clothing: Cotton underwear and loose-fitting clothes reduce moisture build-up and irritation.
Can UTIs Go Away Without Antibiotics?
Some mild UTIs may clear without medication, especially if you’re otherwise healthy and take good care of yourself. However, without antibiotics, there’s a risk of the infection worsening or spreading. It’s best to speak to a healthcare professional, especially if symptoms last more than a couple of days or worsen.
Who Is at Higher Risk of UTIs?
You may be more prone to developing a UTI if you:
- — Are female (due to shorter urethras)
- — Are sexually active
- — Are postmenopausal
- — Use certain forms of birth control (like diaphragms)
- — Have urinary retention or a catheter
- — Have diabetes or a weakened immune system
If you have frequent UTIs, it’s important to discuss this with your pharmacist or GP, as you may need preventative advice or further investigation.
When to Seek Further Medical Advice
While most UTIs are mild and resolve with treatment, there are times when you should seek more urgent medical attention:
- — Symptoms lasting more than 5 days with no improvement
- — High fever or chills
- — Blood in your urine
- — Back pain or pain around the kidneys
- — Nausea or vomiting
- — Recurrent UTIs
At Market Harborough Pharmacy, we’ll let you know if a referral to a GP or specialist is necessary.
