Uncomplicated Urinary Tract Infections
2 medicines
An uncomplicated UTI is a bacterial infection of the bladder or urethra in an otherwise healthy person. A short antibiotic course usually clears it; kidney symptoms need prompt review.
Key facts
- An uncomplicated urinary tract infection (UTI) is a bacterial infection confined to the bladder or urethra in an otherwise healthy person with no structural abnormality.
- Typical symptoms are burning on passing urine, a frequent or urgent need to go, and cloudy or strong-smelling urine, often with pelvic discomfort.
- A short course of antibiotics works well: norfloxacin acts directly on the urinary tract, and cefixime is used where fluoroquinolone resistance is a concern.
- Fever, back or flank pain, nausea or vomiting suggest the kidneys are involved and need prompt medical attention, not self-treatment.
Who gets them and why
Women are far more likely than men to develop uncomplicated UTIs, largely because a shorter urethra sits closer to the bladder. Recurrent episodes are common, particularly after sexual activity, during pregnancy, or after antibiotic courses that disrupt normal flora.
Recognising the symptoms
The classic presentation is a burning sensation when urinating, a frequent or urgent need to pass urine, and cloudy or strong-smelling urine, with pelvic discomfort also common. Fever, back or flank pain, nausea or vomiting suggest the infection may have reached the kidneys, which warrants prompt medical attention.
Antibiotic treatment
Uncomplicated UTIs respond well to a short course of antibiotics. Norfloxacin is a fluoroquinolone with a long history of use for bladder infections, and cefixime is an oral cephalosporin used where fluoroquinolone resistance is a concern. Drinking plenty of water during treatment helps flush bacteria from the bladder and may ease discomfort more quickly.
