Educational information — not medical advice.
This article was prepared by the OnlineDoctor24 editorial team and reviewed for factual accuracy against UK clinical guidance (NHS and NICE). It is not written by a doctor and does not replace personal medical advice. For symptoms specific to you, book an online doctor consultation.
Key points
- UTIs cause burning, urgency, frequency and lower-tummy pain.
- Most uncomplicated UTIs in women respond to a 3-day course of nitrofurantoin or trimethoprim.
- Drink plenty of water; over-the-counter cystitis sachets help symptoms.
- An online GP can prescribe antibiotics same-day after assessment.
- Red flags: fever, flank pain, blood in urine, vomiting — seek urgent care.
Symptoms
- Burning or stinging on passing urine
- Frequent urge to wee, even when bladder is empty
- Lower-tummy or pelvic discomfort
- Cloudy, smelly or pink urine
- Feeling generally unwell
Self-care
- Drink plenty of water.
- Paracetamol or ibuprofen for pain.
- Cystitis relief sachets (e.g. potassium citrate) ease symptoms but don't treat infection.
- Cranberry products may reduce recurrence (limited evidence).
Antibiotic treatment
- Nitrofurantoin 100 mg modified-release twice daily for 3 days — first line in women.
- Trimethoprim 200 mg twice daily for 3 days — alternative.
- Men and pregnant women need different/longer regimens — your GP will advise.
- Recurrent UTIs (>3/year) may benefit from low-dose suppressive antibiotics or vaginal oestrogen post-menopause.
When an online doctor can help
Online GPs commonly prescribe UTI antibiotics same-day after a brief video assessment. They will check for red flags and refer for urine culture if symptoms recur or don't settle.
Red flags — when to seek urgent help
Call 999 or go to A&E if you experience any of the following:
- High fever, shivers (rigors)
- Pain in the flank/back (possible kidney infection)
- Blood in urine
- Vomiting / unable to keep fluids down
- Confusion in older adults
- UTI in pregnancy or in a man — needs different management
