A lower urinary tract infection - sometimes called cystitis or a bladder infection - usually comes on quickly over a few hours. The picture is fairly recognisable.
- Burning or stinging when you wee. This is the most common symptom and the one almost everyone notices first.
- Needing to wee more often than normal, often with very little urine coming out each time.
- A sudden, hard-to-postpone urge to go - sometimes called urgency.
- Urine that looks cloudy or smells stronger than usual.
- Pain or pressure low down in your tummy, just above the pubic bone.
- A small amount of blood in the urine. This is common in straightforward UTIs and is usually not a sign of something serious, particularly when the other symptoms above are present.
Three or more of these symptoms together make a UTI very likely. One in isolation - for example, frequency without burning - is more ambiguous and may need a different assessment.
A small number of features take a UTI out of the "uncomplicated" category and into a situation that needs in-person assessment - sometimes urgently. Go to your nearest Centro de Salud or Urgencias in any of the following cases.
- Fever, chills, or feeling generally unwell with the urinary symptoms
- Pain in your lower back, sides, or where you would expect your kidneys
- Nausea or vomiting alongside the UTI symptoms
- You are, or might be, pregnant
- The symptoms have lasted more than seven days
- You have had three or more UTIs in the past 12 months
- You finished a course of antibiotics for a UTI in the last four weeks and the symptoms are back
- You have a urinary catheter, or have had recent urological surgery
- You have diabetes, kidney disease, a structural bladder problem, or you are immunosuppressed
- You also have unusual vaginal discharge, itching, or soreness - these point to a different diagnosis
- You are a man, or registered male at birth - UTI in men is uncommon and needs in-person assessment
For genuine emergencies - severe pain, very high fever, confusion, fainting, or any sign of sepsis - call 112.
- Men - urinary symptoms here need in-person assessment
- Pregnancy, suspected pregnancy, or breastfeeding - needs in-person care and different treatment
- A first UTI, or symptoms that aren't the typical burning and frequency - the diagnosis may need a urine test in person
- Recurrent UTIs (three or more in 12 months), or symptoms returning within four weeks of antibiotics
- A urinary catheter, recent urological surgery, or a known bladder or kidney problem
- Diabetes, kidney disease, or a weakened immune system
- Any red-flag symptoms in the box above - these point to a kidney infection
A Spanish farmacia will help quickly, without an appointment, and without a prescription. What they can offer:
- A simple painkiller - paracetamol or ibuprofen - for the burning sensation and any tummy ache.
- Urinary alkalinisers, sold as sachets or effervescent tablets. These do not treat the infection itself but can take some of the sting out of weeing.
- Cranberry products and D-mannose. The evidence for these is mixed and they will not clear an established infection, but they are harmless and many people find them comforting.
- Advice on fluids - drink plenty of water; it dilutes the urine and helps flush bacteria out. Avoid alcohol while symptoms are active.
- A pharmacist referral if they suspect the picture is not straightforward - Spanish pharmacists are clinically trained and will not hesitate to send you to a doctor if something looks off.
Antibiotics for a UTI need a prescription in Spain and cannot be sold over the counter. Some other countries dispense them more freely; Spain does not.
For an uncomplicated lower UTI with a clear symptom picture, a short course of the right antibiotic clears the infection in the great majority of cases. Most women feel a noticeable improvement within 24 to 48 hours of the first dose.
Two practical points worth knowing.
- The right antibiotic is country-specific. Spanish bacterial resistance patterns differ from those in the UK, Ireland, the US, or anywhere else. The medicines that work best for an uncomplicated UTI in Spain are determined by Spanish urology guidance and local data. Bringing an unfinished pack from home, or asking a friend for theirs, often means taking something that does not match local resistance.
- The choice between the available options is clinical. Kidney function, allergies, other medications, and how recently you have had antibiotics all matter. That is what the consultation is for.
If symptoms have not improved after two days of the right antibiotic, or are getting worse, you should be seen again. The antibiotic may need switching, or the diagnosis may need revisiting.
Three routes, with the trade-offs that apply to most non-urgent prescription needs in Spain.
Public route: Centro de Salud
With an EHIC, a UK GHIC, or a Spanish tarjeta sanitaria, any Centro de Salud will see you for an uncomplicated UTI. Same-day availability varies by region - busy coastal areas in summer can be difficult to book on the same morning.
Private in-person GP
A private GP appointment runs around EUR 50 to 120, usually with same-day availability. English-speaking clinicians are common in cities and on the coast. You leave with a Spanish receta privada.
Online private consultation
UTI is one of the textbook cases for online prescribing. The diagnosis is built from symptoms, not a physical examination, and the question set the doctor needs to answer is short. An online consultation usually takes around five minutes; a doctor reviews it the same day and, where appropriate, issues a Spanish receta privada dispensable at any pharmacy.
We do not currently treat this online, but if you would like to be kept informed of our services please let us know.
Most prevention advice for UTI is straightforward, low-cost, and supported by reasonable evidence.
- Drink enough water. Pale-yellow urine is roughly the right target through the day.
- Don't hold your urine when you need to go. Long delays are a common trigger, especially on travel days.
- Pee shortly after sex. This is the single most reliable behavioural step for people who get UTIs after intercourse.
- Wipe from front to back. Standard advice, occasionally still worth saying.
- Avoid harsh soaps on the genital area. Plain water or a gentle, fragrance-free wash is enough.
- If you are post-menopausal and prone to UTIs, ask a GP about local vaginal oestrogen. It is highly effective and under-used.
- Cranberry and D-mannose have weak but real evidence for reducing recurrence in some women. Worth trying if you are prone, but not a substitute for medical assessment when a UTI is active.
Important. UTI with fever or back pain, UTI in pregnancy, recurrent UTI, UTI in men, or any of the situations listed under section 2 need in-person care - not an online consultation. If there is any possibility your situation is an emergency, call 112.
