Antibiotics for recurrent urinary tract infections

A urine sample is particularly useful when infections keep returning because it can identify the bacterium and show which antibiotics are likely to work. Previous culture results, allergies, pregnancy, kidney function, recent antibiotic use and the severity of symptoms all influence the prescription.

Burning urination, urgency and frequent small amounts of urine can occur with a bladder infection, but vaginal irritation, some sexually transmitted infections and bladder pain conditions can feel similar. Repeated treatment without checking the diagnosis may expose you to side effects while leaving another cause untreated.

Clinicians review whether infections are linked to sex, menopause, urinary retention, stones or another urinary tract problem. Further examination or imaging is reserved for patterns or findings that suggest an underlying issue.

Provide a urine sample before the first dose when your clinician requests one and it is safe to wait. Take the prescribed course as directed, do not share antibiotics, and do not keep unused tablets for self-treatment unless you have been given a specific clinician-led plan.

Drink according to thirst and avoid delaying urination for long periods. Depending on the pattern, a clinician may discuss a patient-initiated course, a preventive low-dose regimen, or medicine linked to a recognised trigger. After menopause, local vaginal oestrogen may be considered when suitable because it supports the tissues around the vagina and urethra.

Seek same-day medical care for fever, chills, pain in your side or back, vomiting, marked weakness, or worsening symptoms despite treatment. These features can occur when infection involves the kidneys and may require different testing or treatment.

Prompt assessment is also appropriate during pregnancy, when you cannot pass urine, or when visible blood persists after infection symptoms settle. Call emergency services for confusion, fainting, severe breathing difficulty or rapidly deteriorating wellbeing.

Ask whether your previous urine cultures show the same bacterium, when to provide a sample, and which symptoms should trigger urgent care. Discuss whether you need a self-start or preventive prescription, how it will be reviewed, and whether vaginal oestrogen or investigation for an underlying cause suits your situation.
