How UTI antibiotics work, and why the choice varies
The likely bacteria, infection site, kidney function and local resistance data all shape a UTI prescription. See why one antibiotic does not fit every case.
DIRECT ANSWER
An online consultation lets an EU-licensed doctor review your case and, if appropriate, issue an electronic prescription; each pharmacy decides whether it can dispense it.
Doctor reply in under 2 hours
Average doctor reply under 2 hours; at night and on public holidays it can take longer, always within 24 hours. A prescription only if appropriate.
EU-licensed doctors
Every case is reviewed by an EU-licensed doctor.
Electronic prescription
Each pharmacy decides whether it can dispense an approved prescription; some do not accept PDF prescriptions.

Antibiotics treat susceptible bacteria; they do not directly numb burning or work against every cause of urinary symptoms. For an uncomplicated lower UTI, a clinician chooses an option that reaches the urine effectively while limiting unnecessary broad antibiotic exposure.
Why different UTIs receive different medicines
Bladder and kidney infections are not interchangeable. Kidney function, pregnancy, sex, age, allergies, recent antibiotics and previous cultures can all change which medicine is safe and likely to work. Local resistance patterns matter because E. coli, the most common bacterial cause, does not respond uniformly across Europe.
When a urine test helps
A typical first lower UTI may be treated from symptoms in some care pathways. A culture becomes more valuable with pregnancy, recurrent or complicated infection, treatment failure, unusual symptoms, resistant-organism history or suspected kidney involvement. The sample can identify bacteria and show which antibiotics are active.
What improvement should look like
Symptoms should begin to settle after effective treatment, but bladder irritation may not disappear with the first dose. Take the medicine exactly as prescribed and ask if there is no improvement within the advised interval or symptoms worsen. Do not save tablets for a future episode; the next set of symptoms may have a different cause.
When to seek help
Fever, shaking chills, pain in the back or side under the ribs, vomiting, confusion, pregnancy, visible blood in urine, rapidly worsening symptoms or feeling seriously unwell need prompt in-person assessment. Men, children, people with catheters, kidney disease, reduced immunity or recurrent infections may also need testing and a different care route. Antibiotics left over from another illness are not a safe shortcut.
What to prepare for a medical review
A clinician will ask about burning, frequency, urgency, pain, discharge, blood, fever, pregnancy possibility, recent antibiotics, allergies, kidney function and previous urine-culture results. A urine sample is useful in some situations but is not required for every straightforward lower UTI. The safest choice depends on the likely site of infection and local resistance patterns.
A calm next step
A narrow, suitable antibiotic is good care, not a weak response. Complete the agreed course, monitor the red flags and use follow-up if the recovery does not match the plan.
