Cystitis treatment: which antibiotics the doctor prescribes — and why

European guidance for an uncomplicated bladder infection in a non-pregnant woman is specific, and the doctors on Mobi Doctor follow it. The first-line options are fosfomycin trometamol as a single 3 g dose, nitrofurantoin for five days, or pivmecillinam for three to five days. They are chosen because they clear a bladder infection reliably, spare the antibiotics needed for more serious infections, and keep low resistance rates across most of Europe.

Which one you get depends on your answers. An antibiotic that worked for you before is usually the doctor's first choice; nitrofurantoin is avoided when the kidneys work less well; allergies rule options out; and if you finished a course in the last few weeks the doctor may pick a different class. Amoxicillin on its own is not used, because too many bladder bacteria resist it, and ciprofloxacin and the other fluoroquinolones are kept for complicated infections, where their side effects are worth it.

Alongside the antibiotic: paracetamol or ibuprofen for the pain, and enough water to keep your urine pale. The doctor's note in your profile says exactly how to take the course.

How quickly it works — and what to do if it doesn't

Most women feel a clear difference within 24 hours and are back to normal within one to three days; the burning goes first, the urgency last. Finish the course even if you feel well. If you are no better after 48 hours, or worse at any point — fever, shivering, pain in your back or side, vomiting — do not wait for the course to end. That is the point at which a bladder infection may be climbing towards the kidneys, and a doctor needs to see you that day. Message the doctor through your profile or book a video consultation; if you feel seriously unwell, go to a doctor in person.

Do I need a urine test?

Not for a typical cystitis. When a woman has burning, frequency and urgency, no vaginal discharge or irritation, and has had the same before, the diagnosis is right more than nine times out of ten from the symptoms alone. That is why European guidance does not ask for a dipstick or a culture in that situation. A culture matters when the picture is different: symptoms that do not settle on antibiotics, an infection that returns within a few weeks, pregnancy, men, children, or signs of a kidney infection. In those cases the doctor tells you where to get one.

Using the prescription at a pharmacy in Spain, Germany, Italy or anywhere else in the EU

The prescription is issued in English by an EU-registered doctor, names the active ingredient — fosfomycin, nitrofurantoin or pivmecillinam — rather than a brand, and carries a verification code the pharmacist can check at mobidoctor.eu/verify. A prescription issued in one EU country must be recognised in another (Directive 2011/24/EU), and the active-ingredient name is what makes that work in practice: the pharmacist hands you the local product. Dispensing is the pharmacist's decision under the rules of the country you are in, and depends on the medicine being available there.

Bring ID. In Spain, Italy, Greece and Portugal a duty pharmacy (farmacia de guardia, farmacia di turno, εφημερεύον φαρμακείο, farmácia de serviço) is open through the night and listed on the door of every closed one; in Germany the Apotheken-Notdienst works the same way. You pay the pharmacy for the medicine itself.

UTIs that keep coming back

Three or more infections in a year, or two in six months, is a recurrent UTI, and it deserves more than another course. The Express Assessment treats the infection you have now; for the pattern, book a video consultation. The options with evidence behind them, in the order the EAU guideline tries them, are vaginal oestrogen after the menopause and other non-antibiotic prevention, then a low-dose antibiotic taken after sex when that is the trigger or, for some women, a supply to start yourself at the first sign of symptoms. Cranberry and D-mannose are harmless, but the evidence for them is weak.

What is a Urinary Tract Infection?

A urinary tract infection (UTI) can occur in any part of the urinary system, which includes the kidneys, ureters (the tubes connecting the kidneys to the bladder), bladder, and urethra (the tube that carries urine out of the body). However, most UTIs occur in the lower part of the urinary system, which means the bladder and urethra are usually affected.

UTIs are more common in women than men because women have a shorter urethra, making it easier for bacteria, especially E. coli, to enter the bladder. Common symptoms include needing to pee often, pain when peeing, and sometimes pain in the lower back or sides.

UTIs are one of the most common infections in people. About half of all women will have a UTI at some point; UTIs are far less common in men. Most infections are not severe, but if they spread to the kidneys, they can cause more serious health problems.

Symptoms of Urinary Tract Infection

A urinary tract infection can cause many symptoms depending on the affected part of the urinary system. Some of them are given below:

• A strong urge to pee that doesn't go away
• A burning feeling when you pee
• Needing to pee often, but only a little comes out
• Pee that looks cloudy or smells bad
• Pee that looks red, pink, or dark, which may be blood
• Pain in the lower belly (for women)
• Pain in the rectum (for men)
• Pain in the lower back or stomach
• Feeling very tired or shaky
• Wetting the bed (in children or older people)
• Feeling confused (mostly in older people)

Severe Symptoms (If the infection reaches the kidneys) 

• Pain in your upper back or sides
• Fever and chills
• Nausea or vomiting

If you have any of these symptoms, especially fever or back pain, you must see a doctor quickly for treatment.

Types of urinary tract infections

Urinary tract infections (UTIs) can occur in different parts of the urinary system, including the kidneys, bladder, and urethra. The symptoms can vary depending on the location of the infection. There are three main types of UTIs: cystitis, pyelonephritis, and urethritis.

1. Cystitis (Bladder Infection)

Cystitis is the most common type of UTI and affects the bladder. If you have cystitis, you might feel like you need to pee a lot, but only a little comes out each time. Peeing might hurt or burn, and your urine might look cloudy, have blood in it, or smell bad. You might also feel pain or pressure in your lower belly.

2. Pyelonephritis (Kidney Infection)

Pyelonephritis is a more severe infection that affects the kidneys. It can happen when bacteria from the bladder travel up to the kidneys. This infection can make you feel very sick, with symptoms like a high fever, chills, nausea, vomiting, and pain in your upper back or sides. If you have a kidney infection, seeing a doctor immediately is essential, as it can lead to more severe health problems if not treated quickly.

3. Urethritis (Urethra Infection)

Urethritis is an infection of the urethra, the tube that carries urine out of the body. Its main symptoms include a burning feeling when peeing and, sometimes, discharge from the urethra. This type of infection can also be caused by bacteria or, in some cases, sexually transmitted diseases.

A doctor must treat each type of UTI to avoid complications. While bladder infections are the most common and usually less severe, infections that reach the kidneys can be much more severe and require quick medical attention.

Causes of Urinary Tract Infections

A urinary tract infection (UTI) occurs when bacteria enter the urinary system, usually through the urethra, and start growing in the bladder. The body normally works to keep out bacteria, but sometimes, bacteria can get through and cause an infection.

The most common cause of UTIs is Escherichia coli (E. coli), a type of bacteria in the digestive system. In women, the urethra is close to the anus, so it’s easier for E. coli and other bacteria to move from the anus to the urethra and into the bladder. Once in the bladder, these bacteria can grow and cause an infection. While E. coli is the leading cause, other bacteria like Proteus mirabilis and Staphylococcus saprophyticus can also lead to UTIs.

Women are more likely to get UTIs than men because their urethra is shorter, which means bacteria can reach the bladder faster. Sexual activity can increase the chance of getting a UTI, but UTIs can happen even if you're not sexually active.

Other things that increase the risk of UTIs include not being able to fully empty the bladder, having kidney stones, or having diabetes. Using a catheter, having poor hygiene, or having had UTIs in the past can also raise the chances of getting one.

Good hygiene, such as wiping from front to back after using the toilet, is often advised, though the evidence that it prevents UTIs is weak. Getting treated quickly helps prevent the infection from spreading, especially to the kidneys, which can cause more severe problems.

Risk factors for Urinary Tract Infection

Urinary tract infections (UTIs) can happen to both men and women, but they are more common in women. Different factors can increase the chances of getting a UTI, depending on your age, gender, and health. Knowing these risk factors can help you avoid UTIs.

1. Body Differences (Anatomy)

• Women: Women are more likely to get UTIs because they have a shorter urethra (the tube that carries urine out of the body). This makes it easier for bacteria to reach the bladder and cause an infection.
• Men: Men are less likely to get UTIs, but older men are at higher risk, especially if they have problems with their prostate. An enlarged prostate can block the flow of urine, which can lead to infections.

2. Sexual Activity

• Women: Being sexually active increases the risk of UTIs because bacteria can be pushed into the urinary tract during sex. The risk is higher if you have a new sexual partner or use certain birth control methods, like diaphragms or spermicide.
• Men: Men who practise anal sex or who are uncircumcised may have a higher risk of UTIs due to increased exposure to bacteria.

3. Hormones and Age

• Women: After menopause, women produce less oestrogen, which causes the tissues in the urethra and bladder to become thinner and more prone to infection. Pregnancy can also increase the risk because the changes in the body slow down urine flow.
• Men: Older men, especially those over 50, are more at risk of UTIs because prostate problems can block the bladder from emptying.

4. Problems with the Urinary Tract

Some people are born with urinary tract problems that make it hard to empty the bladder fully. This can cause urine to back up, making it easier for bacteria to grow. Other issues like kidney stones or an enlarged prostate in men can also increase the risk.

5. Medical Conditions and Catheters

People with weakened immune systems, like those with diabetes, are more likely to get UTIs. Diabetes can make it harder for the body to fight infections, and high sugar levels in the urine can help bacteria grow.

Catheters, tubes used to help people urinate, can also increase the chance of a UTI because bacteria can enter the urinary tract through the catheter.

6. Age and Health Problems

Older adults: As people age, they are more likely to get UTIs, especially if they have health issues like incontinence (trouble controlling when they urinate). Using a catheter also raises the risk of infections in older people.

7. Other Risk Factors

• Recurrent UTIs: Both men and women who have had a UTI before are more likely to get another one. Women who had their first UTI at a young age or have a family history of UTIs are also more at risk.
• Prostate issues (in men): Men with an inflamed prostate (called prostatitis) are more likely to get UTIs because the prostate can block urine from flowing properly.

To reduce the chances of getting a UTI, it’s essential to practise good hygiene, drink plenty of water, and see a doctor if you have symptoms of an infection.
