Recurrent UTI in non-pregnant Women ≥ 3 UTIs/year
TARGET UTIs - includes patient information leaflets on self-care and prevention
SAPG - Recurrent UTI Guidance and UTI management decision aids
Recurrent definition: 2 episodes in 6 months or 3 or more episodes per year
First line:
Advise simple measures for all patients;
- Ensure adequate hydration
- Post coital urination
- Personal hygiene measures (give TARGET self-care leaflets - link above)
- ibuprofen or paracetamol for symptom relief
- Cranberry products or D-mannose (if e. coli. UTI) provide symptomatic relief for some women.
- If diabetic ensure good blood glucose control
- Review all medicines to ensure no drugs that increase risk of UTI (e.g. SGLT2i, anticholinergics, benzodiazepines)
Second Line:
Stand by or post-coital antibiotics - see below for options.
Consider methenamine - 1g BD for 6 months (if no renal/hepatic impairment) then review. If improvement in number of episodes continue and review at 12 months.
Consider topical oestrogens for post menopausal patients - use lowest effective dose and review within 12 months
Third line:
Antibiotic prophylaxis - see below for options. Only give regular prophylaxis if patients continue to have recurrence despite all of the above measures being strictly followed.
- Risk of pulmonary fibrosis in patient taking long term nitrofurantoin.
- Rotation of antibiotics to address issues of resistance is NOT recommended
- If patients develop a UTI resistant to the antibiotic currently being taken for prophylaxis do not restart
